The present application relates to a dental composition comprising a) a compound (A) with the following characteristics: only one main chain unit (U) with 6 to 20 carbon atoms, at least 6 carbon atoms of the same forming an aromatic or aliphatic cyclic moiety, the other carbon atoms being part of the pendent substituents of the cyclic moiety or being part of the groups connecting to the spacer units, one or more carbon atoms being substituted by an oxygen atom, the moiety main chain not comprising a structure of bisphenol and halogen atoms, one or two unit (s) (S) being connected to the main chain unit (U) via an ether bond, at least one unit (S) ) comprising a -CH2-CH2-CH2-CH2-O-CH2-CH2-CH (Q) -OG portion or a -CH2-CH (OG) -CH2-OM portion or a mixture of these two types of portions within a unit (S), with G comprising at least a polymerizable portion and a urethane portion, the portion of urethane acting as a connecting element to the unit (s) (S) and M comprising the (...). 1/56 “DENTAL COMPOSITION, PARTS KIT AND USE OF THE SAME” Field of invention The invention relates to a composition comprising a hardenable compound, containing a comparable rigid main chain unit, a spacer unit and a unit comprising polymerizable terminal groups which are connected to the spacer unit via urethane portions. This composition is useful in the dental field and, in particular, for providing so-called low-stress composite fillers. Background of the technique The volume shrinkage of curable compositions during the curing process has been known for a long time. Specifically in the dental area, this can cause problems as, for example, a gap can be formed between the cured composition and the wall of the dental cavity. This can lead to an infection of the remaining dental structure. Several attempts have been made to address this problem. US 2009/0036565 refers to dental composites based on (meth) acrylates, presenting a proportion of monomers derived from TCD (ie tricycle [5.2.1.0 2 6 ] decane-3 / 4.8 / 9- diila), in which the quotient between flexural strength and shrinkage stress is at least 35. US 2008/0167399 relates to dental composites that comprise a crosslinking agent formed from acrylates and a certain TCD urethane structure. US 7,601,767 B2 refers to a composite material containing a monomer component which comprises a mixture of bis-GMA or TCD-di-HEMA or TCDDiHEA, UDMA and TEDMA. US 4,744,827 relates to certain tricyclodecane (meth) acrylate derivatives that comprise an XYO-CO-C (R5) = CH2 unit where X is a divalent bridge element from the -O-CO group -NH- and -N (R6) -CO-NH- and Y denotes a certain divalent bridge element. JP 8 034707 A describes a photocurable acrylic dental resin composition containing monomers that have a urethane bond and a phenoxy group. US 6,184,339 B1 (Stansbury) relates to fluorinated materials for dental and non-dental uses. Multifunctional monomers and prepolymers with pendent (meth) acrylate groups are prepared by ring opening reactions from epoxides. However, there is still room for improvement specifically with regard to requirements to be met that relate to modern dental materials. Thus, there is still a need for an improved dental composition, which can be used, among other ways, as a temporary and bridge or long-lasting crown material. 2/56 Description of the Invention An object that can be treated by the invention is the provision of a composition that has advantageous properties, for example, with respect to shrinkage stress that can negatively influence the behavior of binding the composition to the surface of a prepared tooth (for example, cavity walls of drug). It may also be desirable that the composition can be cured in layers of comparable thickness (for example, to allow a large filling of a dental cavity). Regardless, certain physical properties such as flexural strength must also be in an acceptable range. According to one embodiment, the present invention features a composition that comprises a) a compound (A) with the following characteristics: only one main chain (U) unit with 6 to 20 carbon atoms, at least 6 carbon atoms of it forming an aromatic or aliphatic cyclic moiety, the other carbon atoms being part of the pendent substituents from the cyclic moiety or making part of the linking groups of the spacer units, one or more of the other carbon atoms being substituted by an oxygen atom, the main chain unit not comprising a bisphenol structure and preferably no halogen atom, one or two unit (s) (S) connected to the main chain unit (U) via an ether bond, at least one unit (S) comprising a -CH2CH2-CH2-CH2-O-CH2-CH (Q) - portion OG or a -CH2-CH (OG) -CH2-OM portion or a mixture of these two types of portions within a (S) unit, with G comprising at least one polymerizable portion and a urethane portion, the urethane portion acting as a connecting element for the unit (s) (S), and M comprising at least one group selected from acroyl, methacryl, aryl, mixtures and combinations thereof, Q comprising at least one group selected from hydrogen, methyl, phenyl, phenoxymethyl, mixtures and combinations thereof, with the proviso that, in the main chain unit (U), at least two substituents are fixed, each containing at least one group G, and in the case where only one unit (S) is present, the group G that is not part of said unit (S) is located in the additional pendant pending on the unit (U), b) filling (B) and c) initiator (C), the composition being a dental composition or to be used in the dental field. 3/56 The invention also relates to a process for producing the composition which comprises a mixing step. According to another embodiment, the invention relates to the use of the composition, as described in the text of the invention, to produce a dental cement, a crown and bridge material, a dental filler material, a casting material, a lining of cavity, a coating composition, a white grinding block, orthodontic devices, a sealant or combinations thereof. The invention is also directed to a kit or parts comprising at least 2 compositions, as described in the text of the invention, the compositions differing at least with respect to their colors. The invention is also directed to the use of the monomers or mixture of monomers of the invention for the production of a dental composition, the process of use comprising the steps of: a) placing the composition comprising the monomer or mixture of monomers as described in this text in contact with a surface, b) harden the composition. In describing the invention, the following terms are defined as follows: The term "visible light" is used to refer to light that has a wavelength of about 400 to about 800 nanometers (nm). A “dental composition” is any composition that can be used in the dental field. On this subject, the composition must not be harmful to the health of the patients and, therefore, free of toxic and dangerous components capable of migrating out of the composition. Examples of dental compositions include permanent and temporary crown and bridge materials, artificial crowns, materials for posterior and anterior filling, adhesives, white grinding blocks, laboratory materials and orthodontic devices. Dental compositions are typically curable compositions, which can be cured under ambient conditions, which include a temperature range of about 15 to 50 ° C or about 20 to 40 ° C within a period of about 30 min or 20 min or 10 min. Higher temperatures are not recommended, as they can cause pain to the patient and can be harmful to the patient's health. Dental compositions are typically supplied to the practitioner in comparable small volumes, i.e. volumes ranging from about 0.1 to about 100 ml or from about 0.5 to about 50 ml or from about 1 to about 30 ml. Thus, the storage volume of useful packaging devices is within these ranges. A "monomer" is any chemical substance that can be characterized by a chemical formula, which has polymerizable groups (including (meth) acrylate groups) that can be polymerized into oligomers or polymers thereby increasing the weight Molecular 4/56. The molecular weight of monomers can usually and simply be calculated based on the given chemical formula. A "hardenable material or compound" is any compound that can be cured or solidified, for example, by heating, which leads to polymerization, chemical crosslinking, radiation-induced polymerization or crosslinking or with the use of a redox initiator. A curable compound can contain only one, two, three or more polymerizable groups. Typical examples of polymerizable groups include epoxy groups and unsaturated carbon groups, such as a vinyl group that is present in the absence of a (methyl) acrylate group. A “resin” contains all the hardenable compounds (monomers, oligomers and / or polymers) that are present in the hardenable composition. The resin can contain only one hardenable compound or a mixture of different hardenable compounds. A “filler” contains all fillers that are present in the curable composition. Only one type of filler or a mixture of different fillers can be used. "Dispersed in the resin" means that the filler particles are present in the resin as unassociated and distinct particles (that is, not agglomerated and not aggregated). A "nanodimensioned filler" is a filler, the individual particles of which have a size in the nanometer region, for example, an average particle diameter less than about 200 nm. Useful examples are given in US 6,899,948 and US 6,572,693, their content especially with reference to nanodimensioned silica particles is incorporated herein by reference. An "initiator or initiator system" is a substance capable of initiating the curing process of a hardenable compound. A “setting, hardening or curing reaction” is used interchangeably and refers to a reaction in which the physical properties such as viscosity and hardness of a composition change over time due to a chemical reaction between the components individual. A “derivative” is a chemical compound that shows a chemical structure that is very close to the corresponding reference compound and that contains all the structural elements depicted in the corresponding reference compound, but that has minor modifications such as adding comparably small additional chemical groups such as, for example, CH 3 , Br, Cl or F or not having comparably small chemical groups such as, for example, CH 3 compared to the corresponding reference compound. The following examples should illustrate this: tetramethyl bisphenol A which has four additional methyl groups with respect to the reference compound bisphenol A, 5/56 and bisphenol F which does not have two additional methyl groups with respect to the reference compound bisphenol A are derived from bisphenol A within the meaning of this definition. "Ambient conditions" means the conditions under which the composition of the invention is usually subject during storage and handling. Ambient conditions can, for example, have a pressure of about 90 to about 110 kPa (900 to about 1100 mbar), a temperature of about -10 to about 60 ° C and a relative humidity of about 10 to about 100%. The laboratory ambient conditions are adjusted to about 23 ° C and about 101 kPa (1013 mbar). The ambient conditions of the dental and orthodontic field are reasonably understood as a pressure of about 95 to about 105 kPa (950 to about 1050 mbar), temperature of about 15 to about 40 ° C and relative humidity of about 20 about 80%. For use in the present invention, "one", "one", "the one", "at least one" and "one or more" are used interchangeably. The terms "understand" or "contain" and variations thereof do not have a limiting meaning in the way in which these terms appear in the description and claims. For use in the present invention, recitations of numeric ranges with extremes include all continuous numbers in this range (for example, 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.). Except where otherwise noted, all figures expressing quantities of ingredients, measurement of properties as a contrast ratio and so on used in the specification and claims are to be understood as being modified in all instances by the term "about." Detailed Description of the Invention The composition of the invention is beneficial to the dentist in two aspects. For example, it has been found that compound (A) contained in the composition of the invention contributes to at least one or more of the following properties: a) Compound (A) can have good wetting of the filler / pigment (for example, useful to achieve comparatively high filler loads), b) Compound (A) may have a comparatively high molecular weight (for example, useful for obtaining comparatively low polymerization shrinkage during or after curing, if desired), c) Compound (A) may have a comparatively high refractive index (for example, useful for achieving high depth of cure and / or suitable aesthetics, if desired), d) Compound (A) may have a comparatively high hydrophobic capacity (for example, useful in achieving comparatively low water absorption and / or the production of exogenic stains), e) Compound (A) can be used to provide compositions showing low shrinkage stress during or after curing (for example, useful for avoiding post-operative sensitivity and ensuring long-term marginal integrity), 6/56 f) Compound (A) can be used to provide compositions showing a high cure depth (for example, useful for volume curing applications, if desired), g) Compound (A) can be used to provide compositions with appropriate mechanical properties (i.e., a comparatively high flexural strength). Compositions with appropriate mechanical properties typically contribute to the provision of compositions with comparatively high durability. h) Compound (A) typically shows an E-Modulus medium through standard wear resistance (measured according to ACTA). Compositions with appropriate E-Modulus typically contribute to the provision of compositions with comparatively low brittleness. One or more of these properties can be obtained using a compound that has a comparable rigid main chain unit, a flexible spacer unit of a certain length and urethane units. The combination of low shrinkage stress properties, high cure depth, and appropriate mechanical properties as an E-Modulus medium and / or acceptable flexural strength values is proven to be beneficial, specifically in the dental field. Not wishing to stick to a certain theory, it is believed that the presence of the urethane units contributes to the formation of a secondary network due to their ability to form hydrogen bonds. In addition, it is assumed that the nature and length of the spacer units contribute to influencing the viscosity of the compound. The rigid main chain containing a portion of cyclic carbon can contribute to hydrophobic capacity. Thus, compound (A) shows a unique combination of characteristics that help to provide a dental composition that has advantageous properties, specifically showing low stress during hardening. Compound (A) can be characterized by the following characteristics. • contain only one main chain (U) unit with 6 to 20 carbon atoms, at least 6 carbon atoms of it forming an aromatic or aliphatic cyclic moiety, the other carbon atoms being part of the pendent substituents from one moiety cyclic or forming part of the linker units to spacer units, one or more of the other carbon atoms being substituted by an oxygen atom, the main chain unit not comprising a bisphenol structure and preferably no halogen atom ( for example, F, Cl, Br), • one or two unit (s) (S) being connected to the main chain unit (U) via an ether connection, at least one spacer unit (S) that understands 7/56 a -CH2-CH2-CH2-CH2-O-CH2-CH (Q) -OG chain or a -CH2-CH (OG) -CH2OM residue or a mixture of these two types of spacers within a spacer unit , with G being connected to the spacer unit (s) (S) via a portion of urethane, each group G comprising at least one polymerizable portion and M (preferably not connected to the spacer unit (s) (S) via a portion of urethane e) comprising at least one group selected from acroyl, methacryl, aryl, mixtures and combinations thereof , Q (preferably not connected to the spacer unit (s) (S) via a portion of urethane e) comprising at least one group selected from hydrogen, methyl, phenyl, phenoxymethyl, mixtures and combinations with the proviso that at least two G groups are present in compound (A), and in the case where only one unit (S) is present, the group G that is not part of said unit (S) is located on a pendant substituent from the unit (U) which has two substituents, each having a group G. The term "bisphenol structure" includes structures such as bisphenol A, bisphenol AP (4.4 (1-phenylethylidene) bisphenol), bisphenol C (Bis (4-hydroxyphenyl) -2,2-dichlorethylene), bisphenol F (bis (2 -hydroxyphenyl) methane), bisphenol TMC (4,4- (3,3,5-trimethylcyclohexylidene) bisphenol). These and other abbreviations are known to those skilled in the art. The term "main chain unit" means a unit, which forms a central part of the compound (A). To function as a main chain unit, the main chain unit has to be at least bifunctional or divalent. That is, at least two, three or four substituents are attached to the main chain unit. A unit, which contains only one substituent, cannot be considered as a main chain unit. Such a unit is understood as a pending substituent. The main chain unit (U) comprises at least two substituents, which may be the same or different, each substituent comprising a polymerizable portion. Thus, at least two polymerizable portions are present in two different substituents attached to the main chain unit (U). Alternatively or in other words, compound (A) comprises at least two groups G, which can be the same or different, being - in the case where only one spacer unit (S) is present - the group G that is not part of said spacer unit (S) is located on a pendant substituent from an aromatic or aliphatic cyclic portion. If desired, different compounds within the definition of compound (A) can be present in the composition. For example, the composition of the invention may contain two, three, four or even more compounds, which differ from each other, for example, by the nature of the main chain unit and / or the nature of the spacer unit (s) ( s). 8/56 The compound (Α) can be characterized by at least one or preferably two of the following characteristics, for example (a) and (b), (a) and (c) or (b) and (c): a) Molecular weight (MW): from about 600 to about 1200, b) Functionality: 2 to 4 reactive groups per molecule, c) index of refraction: from about 1,500 to about 1,560 (n D 20 ). If one or more of the above parameters are satisfied, a composition can be provided, having sufficient aesthetic appearance and color stability. This can also be accompanied by desired mechanical values. The main chain unit (U) can comprise a portion selected from * * The spacer unit (s) (S) may comprise a portion selected from S1: OG Q with m = 1a3en = 1a3, Q = hydrogen, methyl, phenyl or phenoxymethyl, OM with M = acroyl, methacryl or phenyl, or OG S3: with M = acroyl, methacryl or phenyl at = 1a3en = 1a3, Q = hydrogen, methyl, phenyl or phenoxymethyl. The symbol indicates a connection point to another portion. “G” can comprise a portion selected from 9/56 combinations and mixtures thereof. According to a specific embodiment, compound (A) can be characterized by a structure, according to any of the formulas (I), (II), (III), (IV), (V), (VI) and (VII) (D with a, b = 0a3, c, d = 0a3 (a + b) = 1 to 6 (c + d) = 1 to 6, 10 Q = hydrogen, methyl, phenyl or phenoxymethyl, G and U as defined above, (II) with R = independently selected from H or methyl, G as defined above, O) with R = H or methyl, G and U as defined above, OG OG (IV) 10/56 with G and U as defined above, GO (V) with R = independently selected from H or methyl, Q = independently selected from hydrogen, methyl, phenyl or phenoxymethyl, G and U as defined above, a, b = 0 to 3 and c, d = 0 to 3 (a + b) = 1 to 6 and (c + d) = 1 to 6, with R = H or methyl, Q = independently selected from hydrogen, methyl, phenyl or phenoxymethyl, G and U as defined above, a, b = 0a3c, d = 0a 3 (a + b) = 1 a6e (c + d) = 1 a6, (VII) with a, b = 0 to 3c, d = 0 to 3 (a + b) = 1 to 6 (c + d) = 1 to 6, Q = independently selected from hydrogen, methyl, phenyl or phenoxymethyl, G and U as defined above, 11/56 combinations and mixtures thereof. With respect to any of the following formulas (I) to (VII), "U" and "G" can be any of the portions presented in the above text together with the description of "U" and "G". Compound (A) is typically present in the composition in an amount of at least about 5% by weight, or at least about 10% by weight, or at least about 20% by weight. The amount of compound (A) contained in the composition is typically up to about 50% by weight, or up to about 60% by weight, or up to about 70% by weight. Typical ranges include about 5 to about 70 or about 10 to about 60 or about 10 to about 45 or about 10 to about 30% by weight. Compound (A) can be obtained or produced according to a very simple process, by reacting, for example, alcohols such as TCD alcohol or ethoxylated resorcinol (ER) or ethoxylated hydroquinone (EH) with epoxies, such as , glycidyl methacrylate (GMA) and / or phenyl glycidyl ether (GP), as well as mixtures containing epoxy such as ethylene oxide (EO) in tetrahydrofuran (THF) or propylene oxide (PO) in THF or oxide of styrene (SO) in THF or GP in THF, also through the reaction of OH acidic compounds, such as methacrylic acid (MA) or phenol with epoxies, such as resorcinol diglycidyl ether (RDGE) or cyclohexane-diglycidyl ether 1,4-dimethanol (CDGE). The OH group (s) of these alcohols and / or acidic OH compounds is / are added under the ring opening in these reagents producing the corresponding ether and / or ester derivatives of, for example, TCD alcohol. If desired, the alcohol reaction can be carried out using a basic catalyst, for example, for the reaction with epoxies (such as for example GMA or GP), respectively with the use of Lewis acid catalyst for the reaction with epoxy containing mixtures (such as EO in THF), the reaction of OH acid compounds can be carried out, for example, for the reaction with epoxies using, for example, a moderate nucleophilic catalyst or a basic catalyst. If desired for the reaction of triethylamine (TEA) and / or 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) and / or triethyl ammonium acetate (TEAA) and / or sodium acetate (NaOAc) and / or potassium acetate (KOAc) and / or potassium tert-butoxide (KOtBu) can be used as a basic catalyst. Alternatively, boron trifluoride etherates i.e. BF 3 * THF and / or BF 3 * OEt 2 can be used as a Lewis acid catalyst. If desired for the reaction of acidic OH compounds, triphenylphosphane (PPh 3 ) can be used as a nucleophilic catalyst. If desired, the crude reaction product (s) can be treated with organic acids to minimize color in the final purified product. 12/56 These ether derivatives can be further reacted with, for example, 2-isocyanatoethyl methacrylate (IEM) or 3-isocyanatopropyl methacrylate (IProM) or 5-isocyanatopentyl methacrylate (IPM) or -2-isocyanatoethyl acrylate (IEA) or 3-isocyanatopropyl acrylate (IProA) or 5-isocyanatopentyl acrylate (IPA) or 1,1bis (methyl acroyloxy) ethyl isocyanate (EIB). The completion of the reaction can be determined by IV spectroscopy, specifically focusing on the NCO band, showing an absorption band at about 2273 cm ' 1 . The reaction can typically be carried out in a temperature range of about 40 to about 110 ° C, preferably under dry conditions (for example, dry air). The reaction can be carried out in ordinary solvents (including hexane, cyclohexane, methylcyclohexane, toluene, ethyl acetate, diethyl ether, methyl-tert-butyl-ether, tetrahydrofuran) or without a solvent. The desired molecular structure of the reaction product can be adjusted by choosing the appropriate molar ratios between the components of the reaction (ie, educts). In an ideal case, if, for example, a di-functional alcohol (HO-X-OH) is reacted with an equivalent of Y, the final reaction product will typically contain a statistical mixture of the following components in the respective proportions: HO-X -OH (25%), Y-OX-OY (25%), YOX-OH (50%). In an ideal case, if, for example, a di-functional alcohol (HO-X-OH) is reacted with two equivalents of Y, the final reaction product will typically contain Y-O-X-O-Y (100%). If desired, further purification of the product mixture can be carried out by means known to the person skilled in the art including HPLC, distillation and fractional crystallization. To avoid polymerization of unwanted radicals during synthesis, a stabilizer in an appropriate amount (for example 50 to 500 ppm) such as 3,5-di-tert-butyl-4-hydroxy-toluene (BHT), 4-methoxyphenol (MOP ) or hydroquinone (HQ) can be used, but it is not mandatory. If desired, compound (A) can be combined with a surface treated with SiO 2 and / or ZrO 2 nanoparticles to obtain dispersions of the surface treated with SiO 2 and / or ZrO 2 nanoparticles within compound (A). The composition of the invention can comprise a filler or a filler matrix. The filler matrix can consist of a filler or a mixture of different fillers. The filling nature of the composition of the invention is not particularly limited. The size of the filler particles must be such that a homogeneous mixture with the hardenable component (s) that forms the resin matrix can be obtained. Useful fillers include smoked silica, fillers based on non-water-soluble fluorides, sandblasted glasses, quartz, fluoroaluminosilicate glasses like CaF 2 , silica gels like silicic acid, in particular, pyrogenic silicic acid and granules thereof, cristobalite, sodium silicate, zirconium silicates, zeolites, including sieves Molecular 13/56, metal oxide powders, such as zinc and aluminum oxides and their mixed oxides, barium sulfate, yttrium fluoride, calcium carbonate. The silica is usually dispersed in the resin matrix. The silica particles used in the dental compositions of the invention preferably have an average diameter of less than about 200 nm; more preferably, the particles are less than about 100 nm in average diameter. These measurements are preferably based on a TEM (transmission electron microscopy) method, so that a population is analyzed to obtain an average particle diameter. A preferred method for measuring the particle diameter can be described as follows: samples approximately 80 nm thick are placed on 200 mesh copper grids with carbon stabilized substrates (SPI Supplies, a division of Structure Probe, Inc., West Chester, PA, USA). A transmission electron micrograph (TEM) is made, using JEOL 200CX (JEOL, Ltd. from Akishima, Japan and sold by JEOL USA, Inc.) at 200 Kv. A population size of about 50 to 100 particles can be measured and an average diameter is determined. The average surface area of the silica particles is preferably greater than about 15 m 2 / g, more preferably greater than about 30 m 2 / g. Once dispersed in the resin, the silica particles are in a discontinuous (individual) condition and are not associated (that is, not agglomerated, not aggregated). "Agglomerated", for use in the present invention, is the description of a weak association of particles usually held together by charge or polarity and can be decomposed into smaller entities. "Aggregates", for use in the present invention, is the description of a strong association of particles often attached to each other through, for example, residual chemical treatment; further decomposition of aggregates into smaller entities is very difficult to achieve. The silica particles that can be used in the dental materials of the invention are preferably substantially spherical and substantially non-porous. Although silica is preferably essentially pure, it can contain small proportions of stabilizing ion such as alkali metal ions and ammonium. Suitable smoked silicas include, for example, products sold under the brand name series AEROSIL OX-50, -130, -150, and -200 available from Degussa AG, (Hanau, Germany) and CAB-O-SIL M5 available with Cabot Corp (Tuscola, III., USA). Useful fluoroaluminosilicate glasses include fillers of treated fluoroaluminosilicate glass, as described in US Patent No. 5,332,429, the description of which is expressly incorporated by reference in the present invention. For example, fluoride-releasing glass can be added to the composition 14/56 dental in order to provide the benefit of long-term release of fluoride in use, for example, in the oral cavity. Optionally, a heavy metal oxide can be included in the dental materials of the invention to provide a radiopaque dental material. It is preferred that the heavy metal oxide is present in an effective amount to confer radiopacity. For use in the present invention, "radiopacity" describes the ability of a hardened dental material to be distinguished from a dental structure using standard dental X-ray equipment in a conventional manner. Radiopacity in a dental material is advantageous in certain instances where X-rays are used to diagnose a dental condition. For example, a radiopaque material would allow the detection of secondary caries that could form in the dental tissue that surrounds a filling. The desired degree of radiopacity can be varied, depending on the particular application and the expectations of the professional who evaluates the film for X-rays. Heavy metal oxides that have an atomic number greater than about 28 may be preferred. The heavy metal oxide could be chosen in such a way that shading or undesired colors are not imparted to the hardened resin in which it is dispersed. For example, iron and cobalt would not be favored, as they impart contrasting and dark colors to the neutral tooth color of dental material. Most preferably, heavy metal oxide is a metal oxide that has an atomic number greater than 30. Suitable metal oxides are the oxides of elements of yttrium, strontium, barium, zirconium, hafnium, niobium, tantalum, tungsten, bismuth, molybdenum, tin, zinc, lanthanide (that is, elements that have atomic numbers in the range 57 to 71, inclusive), cerium and combinations thereof. More preferably, heavy metal oxides that have an atomic number greater than 30, but less than 72, are optionally included in the materials of the invention. Particularly, preferred radiopacifying metal oxides include lanthanum oxide, zinc oxide, tin oxide, zirconium oxide, yttrium oxide, ytterbium oxide, barium oxide, strontium oxide, cerium oxide and combinations thereof. The heavy metal oxide particles can be aggregated. If so, it is preferred that the aggregated particles are less than about 200 nm and, more preferably, have less than about 90 nm in average diameter. In a preferred embodiment, the filling matrix comprises a nanodimensioned filling that includes nanodimensioned silica. Preferred nanodimensioned silicas are commercially available from Nalco Chemical Co. (Naperville, III., USA) under the product designation NALCO COLLOIDAL SILICAS (for example, the preferred silica particles can be obtained using NALCO 1040 products, 1042, 1050, 1060, 2327 and 2329), Nissan Chemical America Company, Houston, Texas, USA (e.g. SNOWTEX-ZL, -OL, -O, -N, -C, -20L, -40 and -50) ; Admatechs Co., Ltd., Japan (e.g. SX009-MIE, SX00915 / 56 MIF, SC1050-MJM, and SC1050-mlV); Grace GmbH & Co. KG, Worms, Germany (for example, those available under the product designation LUDOX, for example, P-W50, P-W30, Ρ-Χ30, P-T40 and P-T40AS); Akzo Nobel Chemicals GmbH, Leverkusen, Germany (for example, those available under the product name LEVASIL, for example, 50/50%, 100/45%, 200/30%, 200A / 30%, 200/40%, 200A / 40%, 300/30% and 500/15%), and Bayer MateriaIScience AG, Leverkusen, Germany (for example, those available under the product name DISPERCOLL S, for example, 5005, 4510, 4020 and 3030). In a preferred embodiment in which the curable resin employs a cationic initiation system, the starting silica is preferably acidic (such as Nalco 1042). The surface treatment of nanodimensioned silica particles before loading them into the dental material can provide a stable dispersion in the resin. "Stable", for use in the present invention, means a dental material in which the particles do not agglomerate after remaining for a period of time, such as about 24 hours, under standard ambient conditions, for example, at room temperature (about 20 to about 22 ° C), atmospheric pressure and without any extreme electromagnetic force. Preferably, the surface treatment stabilizes the nanodimensioned particles so that the particles are well dispersed in the curable resin and result in a substantially homogeneous composition. In addition, it is preferred that the silica be modified on at least a portion of its surface with a surface treatment agent so that the stabilized particle can copolymerize or otherwise react with the curable resin during curing. The silica particles can be treated with a resin-compatible surface treatment agent. Particularly preferred surface treatment or surface modifying agents include silane treatment agents capable of polymerization with a resin. The preferred silane treatment agent includes Y-methacryloxypropyltrimethoxysilane, commercially available under the trade name A-174, commercially available from WITCO OSi Specialties (Danbury, CT, USA) and γ-glycidoxypropyltrimethoxy silane, a product available under the trade name G6720 , available from United Chemical Technologies (Bristol, PA, USA). Alternatively, a combination of surface modifying agents can be useful, with at least one of the agents having a functional group copolymerizable with a curable resin. For example, the polymerization group can be ethylenically unsaturated or a cyclic function subjected to ring opening polymerization. An ethylenically unsaturated polymerization group can be, for example, an acrylate or methacrylate, or a vinyl group. A cyclic functional group subjected to ring-opening polymerization, in general, contains a heteroatom such as oxygen, sulfur or nitrogen and is preferably a 3-membered ring containing oxygen as an epoxide. Other surface modifying agents that generally do not react 16/56 with hardenable resins can be included to accentuate the rheological properties or dispersibility. Examples of silane of this type include, for example, polyethers of aryl or alkyl, alkyl, hydroxy alkyl, hydroxy aryl or functional aminoalkyl silanes. After surface treatment of the silica particles, they can then be combined with a suitable curable resin to form a dental composition of the invention. The filler matrix may comprise at least about 25% by weight or at least about 30% by weight or at least about 40% by weight or at least about 50% by weight of the entire composition. The amount of filler to be used in the filler matrix usually depends on the purpose for which the composition is to be used. The filler matrix may comprise up to about 90% by weight, or up to about 85% by weight, or up to about 80% by weight, or up to about 75% by weight, of the entire composition. Temporary bridge and crown materials (for example, for a dental composition) do not usually contain a high amount of fillers. In relation to these compositions, the filling content is usually in the range of about 30 to about 60% by weight over the entire composition. In dental filling materials (as another example for a dental composition; sometimes also called dental composite materials), which typically contain a greater amount of fillings when compared to temporary bridge and crown materials, the filling content is usually , in a range of about 60 to about 85%, by weight, in relation to the entire composition. The dental composition of the invention also comprises an initiator or initiator system capable of initiating the curing process of the hardenable components present in the resin matrix. The dental materials of the invention can be chemically, heat or light cured compositions. Light-curable materials must have a suitable initiator system. Chemically curable materials can be self-cured (for example through redox initiators). Alternatively, the materials of the invention can be hardened by a combination of self-healing and light curing. For free radical polymerization (hardening), an initiation system can be selected from systems that initiate polymerization through radiation, heat or chemical reaction with redox / self-cure. A class of initiators capable of initiating the polymerization of active free radical functional groups includes free radical generating photoinitiators, optionally combined with a photosensitizer or accelerator. Such initiators may typically be able to generate free radicals for polymerization by 17/56 addition upon exposure to light energy that has a wavelength between about 200 and about 800 nm. A variety of visible or near-IR photoinitiator systems can be used for photopolymerization of free radical polymerizable materials useful in the invention. For example, in free radical polymerization (hardening), a photoinitiation system can be selected from systems that initiate polymerization through a two-component system of an amine and an α-diketone as described in US 4,071,424 and WO 2009151957, which are incorporated herein by way of reference. Alternatively, the resin can be combined with a three-component or ternary photoinitiator system as described in US 5,545,676 and WO 2009151957, which are incorporated herein by reference. In the ternary photoinitiator system, the first component is an iodonium salt, that is, a diaryliodonium salt. The iodonium salt is preferably soluble in the monomer and stable during storage (that is, it does not spontaneously polymerize) when dissolved in the presence of the sensitizer and donor. Accordingly, the selection of a particular iodonium salt may depend to some extent on the monomer, polymer or oligomer, sensitizer and donor in particular chosen. Suitable iodonium salts are described in US 3,729,313, US 3,741,769, US 3,808,006, US 4,250,053 and US 4,394,403, the descriptions of the iodonium salt being incorporated herein by reference. The iodonium salt can be a simple salt (for example, containing an anion such as Cl ', Br', I 'or C 4 H 5 SO 3 ') or a complex metal salt (for example, containing SbF 5 OH 'or AsF and '). Mixtures of iodonium salts can be used if desired. Preferred iodonium salts include diphenyliodonium salts such as diphenyliodonium chloride, diphenyliodonium hexafluorophosphate and diphenyliodonium tetrafluoroborate. The second component in a ternary photoinitiator system is a sensitizer. The sensitizer is desirably soluble in the monomer and is capable of absorbing light at any point in the wavelength range greater than 400 to 1200 nanometers, with more preference greater than 400 to 700 nanometers and with the maximum preference greater than 400 to about 600 nanometers. The sensitizer may also be able to sensitize 2-methyl-4,6-bis (trichloromethyl) -s-triazine, using the test procedure described in US 3,729,313, which is incorporated herein by reference. Preferably, in addition to passing this test, a sensitizer is also selected based in part on stability considerations during storage. Accordingly, the selection of a particular sensitizer may depend to some extent on the monomer, oligomer or polymer, iodonium salt and donor in particular chosen. Suitable sensitizers can include compounds in the following categories: ketones, coumarin dyes (e.g. ketocoumarins), xanthene dyes, acridine dyes, thiazole dyes, thiazine dyes, oxazine dyes, azine dyes, dyes 18/56 aminoketone, porphyrins, polycyclic aromatic hydrocarbons, p-substituted aminostyrene ketone compounds, aminotriaryl methanes, merocyanines, squarish dyes and pyridinium dyes. Ketones (for example, monocetones or alpha-diketones), ketocoumarins, aminoaryl ketones and p-substituted aminostyryl ketone compounds are preferred sensitizers. For applications that require high sensitivity, it is preferable to use a sensitizer containing a portion of julolidinil. For applications requiring deep curing (for example, curing high-fill composites), it is preferred to employ sensitizers that have an extinction coefficient below about 1000, more preferably below about 100, at the desired irradiation wavelength for light curing. Alternatively, dyes that have reduced light absorption at the excitation wavelength by irradiation can be used. For example, a preferred class of ketone sensitizers has the formula: ACO (X) b B, where X is CO or CR 5 R 6 , where R 5 and R 6 can be the same or different, and can be hydrogen, alkyl, alkaryl or arylalkyl, b is zero or one, and A and B are different and can be substituted (having one or more non-interfering substituents) can be the same or unsubstituted aryl, alkyl, alkaryl or arylalkyl groups or A and B together can form a cyclic structure that can be a substituted or unsubstituted cycloaliphatic, aromatic, heteroaromatic or fused aromatic ring. Suitable ketones of the above formula include monocetones (b = 0) such as 2,2-, 4,4 or 2,4-dihydroxy benzophenone, di-2-pyridyl ketone, di-2-furanyl ketone, di-2-thiophenyl ketone, benzoin, fluorenone, chalcone, Michler's ketone, 2-fluoro-9-fluorenone, 2-chlorothioxanthone, acetophenone, benzophenone, 1- or 2-acetonephton, 9-acetylanthracene, 2-, 3- or 9-acetylphenanthren, 4 -acetylbiphenyl, propiophenone, n-butyrophenone, valerophenone, 2-, 3- or 4-acetylpyridine, 3acetylcoumarin and the like. Suitable diketones include aralkylketone such as anthraquinone, phenanthrenquinone, o-, m- and p-diacetylbenzene, 1,3-, 1,4-, 1,5-, 1,6-, 1,7- and 1,8diacetylnaphthalene, 1 , 5-, 1,8- and 9,10-diacetylanthracene and the like. Suitable alpha-diketones (b = 1 and X = CO) include 2,3-butanedione, 2,3-pentanedione, 2,3-hexanedione, 3,4-hexanedione, 2,3-heptanedione, 3,4-heptanedione , 2,3-octanedione, 4,5-octanedione, benzyl, 2,2'-3 3'- and 4,4'dihidroxilbenzzila, furila, di-3,3'-indoliletanedione, 2,3-bomanedione (camphorquinone) , biacetyl, 1,2cyclohexanedione, 1,2-naphtaquinone, acenaftaquinone, and the like. The third component of a ternary initiator system is a donor. Preferred donors include, for example, amines (including aminoaldehydes and aminosilanes), amides (including phosphoramides), ethers (including thioethers), ureas (including thioureas), ferrocene, sulfinic acids and their salts, ferrocyanide salts, ascorbic acid and their salts salts, dithiocarbamic acid and its salts, xanthate salts, ethylene diamine tetraacetic acid salts and salts of tetrafenylboronic acid. The donor can be unsubstituted or substituted with one or more non-interfering substituents. Particularly preferred donors contain a 19/56 electron donor atom like a nitrogen, oxygen, phosphorus or sulfur atom, and a hydrogen atom that can be abstracted attached to an alpha carbon or silicon atom to the electron donor atom. A wide variety of donors is disclosed in US 5,545,676, which is incorporated into the present invention by reference. Alternatively, free radical initiators useful in the invention include the acylphosphine oxide class, as described in US 4,737,593. Such acylphosphine oxides have the following general formula (R 9 ) 2 - P (= O) - C (= O) —R 10 where each R 9 individually can be a hydrocarbyl group such as alkyl, cycloalkyl, aryl and arylalkyl, any of which it can be substituted with a halo-, alkyl- or alkoxy- group or the two R 9 groups can be joined to form a ring together with the phosphorous atom, and where R 10 is a hydrocarbyl group, an S-, O- , or N-containing a five or six-membered heterocyclic group or a -ZC (= O) -P (= O) - (R 9 ) 2 group , where Z represents a divalent hydrocarbyl group such as alkylphenene or phenylene having from 2 to 6 carbon atoms. Preferred acylphosphine oxides useful in the invention are those in which the groups R 9 and R 10 are phenyl or phenyl lower alkyl or substituted lower alkoxy. By "lower alkyl" and "lower alkoxy" is meant those groups having 1 to 4 carbon atoms. Most acylphosphine oxide is phosphine oxide bis (2,4,6-trimethyl benzoyl) phenyl (IRGACURE ™ 819, Ciba Specialty Chemicals, Tarrytown, NY, USA). Tertiary amine reducing agents can be used in combination with an acylphosphine oxide. Illustrative examples of tertiary amines useful in the invention include ethyl 4- (N, N-dimethylamino) benzoate and Ν, Ν-dimethylamino ethyl methacrylate. Commercially available phosphine oxide photoinitiators capable of initiating free radicals when irradiated at wavelengths greater than 400 nm at 1200 nm include a 25:75 mixture, by weight, of phosphine oxide bis (2,6-dimethoxybenzoyl) 2, 4,4-trimethylpentyl and 2-hydroxy-2-methyl-1-phenylpropane-1-one (IRGACURE ™ 1700, Ciba Specialty Chemicals), 2-benzyl-2- (N, N-dimethylamino) -1- (4- morpholinophenyl) -1-butanone (IRGACURE ™ 369, Ciba Specialty Chemicals), bis (h5-2,4-cyclopentadiene-1-yl) -bis (2,6difluoro-3- (1H-pyrrol-1-yl) phenyl) titanium (IRGACURE ™ 784 DC, Ciba Specialty Chemicals), a 1: 1 mixture, by weight, of phosphine oxide bis (2,4,6-trimethyl benzoyl) phenyl and 2-hydroxy-2-methyl1-phenyl propan-1 -one (DAROCUR ™ 4265, Ciba Specialty Chemicals), and ethyl 2,4,4-trimethylbenzylphenyl phosphinate (LUCIRIN ™ LR8893X, BASF Corp., Charlotte, NC, USA). Another free radical initiator system that can alternatively be used in the dental materials of the invention includes the class of ionic dye counterion complex inhibitors comprising a borate anion and a complementary cationic dye. 20/56 The photoinhibitors of the borate salt are described, for example, in US 4,772,530, US 4,954,414, US 4,874,450, US 5,055,372 and US 5,057,393, the descriptions of which are incorporated herein by reference. . Borate anions useful in these photoinitiators in general can have the following formula R 1 R 2 R 3 R 4 B _ , where R 1 , R 2 , R 3 , and R 4 regardless of whether they are unsaturated or alicyclic and saturated alkyl heterocyclic groups , aryl, alcaryl, alyl, arylalkyl, alkenyl, alkynyl. Preferably, R 2 , R 3 , and R 4 are aryl groups and more preferably phenyl groups, and R 1 is an alkyl group and more preferably a secondary alkyl group. Cationic counterions can be cationic dyes, quaternary ammonium groups, transition metal coordination complexes, and the like. Cationic dyes useful as counterions can be methionic, polymethyl, triarylmetin, indoline, thiazine, xanthene, oxazine or acridine cationic dyes. More specifically, the dyes can be cationic dyes of cyanine, carbocyanine, hemicianine, rhodamine and azomethine. Specific examples of useful cationic dyes include methylene blue, Safranino O, and malachite green. The quaternary ammonium groups useful as counterions can be trimethylcetylammonium, cetylpyridinium and tetramethylammonium. Other organophilic cations can include pyridinium, phosphonium and sulfonium. Photosensitive transition metal coordination complexes that can be used include cobalt, ruthenium, osmium, zinc, iron and iridium complexes with binders such as pyridine, 2,2'-bipyridine, 4,4'-dimethyl-2,2'- bipyridine, 1,10-phenanthroline, 3,4,7,8tetramethylphenanthroline, 2,4,6-tri (2-pyridyl-s-triazine) and related ligands. Yet another alternative class of initiators capable of initiating the polymerization of radically free active functional groups includes conventional chemical initiator systems such as a combination of a peroxide and an amine. These initiators, which have a thermal redox reaction, are often called “self-healing catalysts”. They are typically supplied as two-part systems in which the reagents are stored separately from each other and then combined immediately before use. In another alternative, heat can be used to initiate the hardening, or polymerization, of the radically free active groups. Examples of suitable heat sources for the dental materials of the invention include inductive, convective and radiant. Thermal sources must be capable of generating temperatures of at least 40 ° C to 15 ° C under normal conditions or at high pressure. This procedure is preferred to initiate the polymerization of materials that occurs outside the oral environment. Organic peroxide compounds together with so-called activators are also suitable as initiators of the redox system. In particular, compounds such as lauryl peroxide, benzoyl peroxide and p-chlorobenzoyl peroxide and pmethylbenzoyl peroxide can be considered as organic peroxide compounds. 21/56 Suitable as activators are, for example, tertiary aromatic amines, such as the N, N-bis- (hydroxy alkyl) -3,5-xylidines known from US 3,541,068 as well as N, Nbis- (hydroxy alkyl) -3,5 -di-t-butylanilines, in particular N, N-bis - ([beta] -oxybutyl) -3,5-di-tbutylaniline as well as N, N-bis- (hydroxy alkyl) -3,4,5-trimethylaniline . The most suitable activators are also barbituric acids and barbituric acid derivatives as described in US 2003/008967, DE 14 95 520 as well as malonyl sulfamides described in US 4,544,742 (which corresponds to EP 0 059 451). The preferred malonyl sulfamides are 2,6-dimethyl-4-isobutylmalonyl sulfamide, sulfamide 2,6-diisobutyl-4-propylmalonyl, 2,6-dibutyl-4-propylmalonyl sulfamide, 2,6-dimethyl4-ethylmalonyl sulfamide and 2,6-dioctyl-4-isobutyl malonyl sulfamide. For further acceleration, polymerization is, in this case, preferably carried out in the presence of heavy metal compounds and ionogenic halogen or pseudohalogen. Heavy metal is suitably used in the form of soluble organic compounds. Similarly, halide and pseudohalide ions are suitably used in the form of soluble salts, as examples, they can be called soluble amine hydrochlorides, as well as quaternary ammonium chloride compounds. Suitable accelerators are in particular metals from the iron or copper group, preferably copper and iron complexes, and in particular copper complexes. The heavy metal is preferably used in the form of soluble organic compounds. Suitable are, for example, iron carboxylates, copper carboxylates, iron procetonate, copper procetonate, copper naphthenate, copper acetate and iron naphthenate. The initiator is typically present in the composition in an amount of at least about 0.1% by weight, or at least about 0.2% by weight, or at least about 0.3% by weight. The amount of initiator contained in the composition is typically up to about 3% by weight, or up to about 2% by weight, or up to about 1.8% by weight. Typical ranges include about 0.1 to about 3 or about 0.2 to about 2 or about 0.3 to about 1.8% by weight. According to another embodiment, the composition may comprise an additional polymerizable component (D) other than compound (A). Component (D) is typically a radically free polymerizable material, including ethylenically unsaturated monomer, monomers or oligomers or polymers. The polymerizable components contain at least one ethylenically unsaturated bond, and are capable of undergoing polymerization by addition. Such a radically free polymerizable material includes mono-, di- or poly-acrylates and methacrylates such as methyl acrylate, methyl methacrylate, ethyl acrylate, isopropyl methacrylate, n-hexyl acrylate, stearyl acrylate, allyl acrylate, glycerol, diurethane dimethacrylate 22/56 called UDMA (mixture of isomers, for example Rohm Plex 6661-0) being the reaction product of 2-hydroxy ethyl methacrylate (HEMA) and 2,2,4-trimethylhexamethylene diisocyanate (TMDI) , glycerol triacrylate, ethylene glycol diacrylate, diethylene glycol diacrylate, triethylene glycol dimethacrylate, 1,3-propanediol diacrylate, 1,3-propanediol dimethacrylate, propane trimethylol triacrylate, 1,2,4-butane trimethacrylate triol, 1,4-cyclohexane diacrylate diol, pentaerythritol triacrylate, pentaerythritol tetraacrylate, pentaerythritol tetramethacrylate, sorbitol hexacrylate, bis [1- (2-acryloxy)] - p-ethoxyphenylmethyl methoxy (3-bis, 3-pyrethylmethoxy) -2-hydroxy)] - trishydroxyethylisocyanurate p-propoxyphenyldimethylmethane and trimethacrylate; polyethylene glycols bis-acrylates and bis-methacrylates of molecular weight 200-500, copolymerizable mixtures of acrylated monomers such as those of US 4,652,274, and acrylated oligomers such as those of US 4,642,126; and vinyl compounds such as styrene, diaryl phthalate, divinyl succinate, divinyl adipate and divinyl phthalate; polyfunctional met (acrylates) comprising urethane, urea or amide groups, such as those of EP 2007111356, together incorporated by reference. Mixtures of two or more of these free radical curable materials can be used if necessary. If desired, the polymerizable material (s) can (s) contain radically free and cationically polymerizable functionality in a single molecule. These molecules can be obtained, for example, by reacting the diepoxide or polyepoxide with one or more equivalents of an ethylenically unsaturated carboxylic acid. Examples of such materials include the reaction product of UVR-6105 (available from Union Carbide) or DER 332 (available from Dow Chemical Co.) with an equivalent of methacrylic acid. Commercially available materials that have radically free and epoxy polymerizable features include the “Cyclomer” series, such as Cyclomer M100 or M101, available from Daicel Chemical, Japan. If present, component (D) is typically present in the composition in an amount of at least about 5% by weight, or at least about 10% by weight, or at least about 20% by weight. If present, the amount of component (D) contained in the composition is typically up to about 45% by weight, or up to about 55% by weight, or up to about 65% by weight. If present, typical ranges include about 5 to about 65 or about 10 to about 55 or about 10 to about 40 or about 10 to about 25% by weight. The polymerizable material (s) may also contain a softener (E) not comprising the polymerizable groups. The softener (E), however, can comprise hydroxyl functionalities. 23/56 If present, the softener may contain two or more primary or secondary aliphatic hydroxyl groups (i.e., the hydroxyl group is attached directly to a non-aromatic carbon atom). The hydroxyl groups can be terminally located, or they can be pendent from a polymer or copolymer. The molecular weight of hydroxyl-containing organic material can vary from very low (for example, 32) to very high (for example, a million or more). Suitable hydroxyl-containing materials can have low molecular weight, that is, about 32 to 200, intermediate molecular weight, that is, about 200 to 10,000 or high molecular weight, that is, above about 10,000. For use in the present invention, all molecular weights are weight average molecular weights. The hydroxyl group-containing material can optionally contain other functionalities that do not substantially interfere with cationic polymerization at room temperature. Thus, materials containing hydroxyl group may be non-aromatic in nature or may contain aromatic functionality. The hydroxyl-containing material can optionally contain hetero atoms in the main chain of the molecule, such as nitrogen, oxygen, sulfur and the like, as long as the latter hydroxyl-containing material does not substantially interfere with cationic polymerization at room temperature. The material containing hydroxyl group can, for example, be selected from naturally occurring or synthetically prepared cellulosic materials. Logically, the material containing hydroxyl group is also substantially free of groups that may be thermally or photolithically unstable; that is, the material will not decompose or release more volatile components at temperatures below about 100 ° C or in the presence of actinic light that can be found during the desired polymerization conditions for the photocopolymerizable composition. Representative examples of suitable hydroxyl-containing materials having the hydroxyl functionality of 1 include alkanols, polyoxyalkylene glycols monoalkyl ethers, alkylene glycols monoalkyl ethers and others known in the art. Representative examples of useful monomeric polyhydroxy organic materials include alkylene glycols (e.g., 1,2-ethanediol; 1,3-propanediol 1,4-butanediol; 1,6-hexanediol; 1,8-octanediol; 2-ethyl-1,6-hexanediol; bis (hydroxymethyl) cyclohexane; 1,18-dihydroxyoctadecane; 3-chloro-1,2-propanediol); polyhydroxyalkanes (for example, glycerin, trimethylolethane, pentaerythritol, sorbitol) and other polyhydroxy compounds such as N, Nbis (hydroxyethyl) benzamide; 2-butino-1,4-diol; 4,4-bis (hydroxymethyl) diphenylsulfone; castor oil and the like. Representative examples of materials containing useful polymeric hydroxyl group include polyoxyethylene and polyoxypropylene glycols and, in particular, polyoxyethylene and polyoxypropylene glycol diols and triols which have molecular weights of about 200 to about 10,000 that correspond to an equivalent weight of hydroxy from 100 to 5000 for diols or 70 to 3300 for triols; polytetramethylene ether glycols such as polytetrahydrofuran or “poly 24/56 THF ”of different molecular weight; copolymers of hydroxypropyl and hydroxyethyl methacrylates and acrylates with other free radical polymerizable monomers such as acrylate esters, vinyl halides or styrene; copolymers containing pendent hydroxy groups formed by hydrolysis or partial hydrolysis of vinyl acetate copolymers, polyvinyl acetal resins containing pendent hydroxyl groups; polymers of modified cellulose such as hydroxypropylated and hydroxyethylated cellulose; hydroxy-terminated polyesters; hydroxy-terminated polylactones and, particularly, polycaprolactones; fluorinated polyoxyethylene or polyoxypropylene glycols; and hydroxy-terminated polyalkanes.

The amount of hydroxyl group-containing organic material optionally used in the compositions of the invention can vary over wide ranges, depending on factors such as the compatibility of the hydroxyl-containing material with the resin, the equivalent weight and the 25/56 functionality of the material containing hydroxyl, the desired physical properties in the final cured composition, the desired speed of light curing, and the like. Mixtures of various materials containing hydroxyl groups are also considered in this invention. Examples of such blends include two or more molecular weight distributions of hydroxyl-containing compounds, such as low molecular weight (below 200), intermediate molecular weight (about 200 to 10,000) and higher molecular weight (above about 10,000). Alternatively or additionally, the material containing hydroxyl may contain a blend of materials containing hydroxyl that have different chemical natures, such as aliphatic and aromatic, or functionalities, such as polar and non-polar. As an additional example, an element can use mixtures of two or more polyfunctional hydroxy materials or one or more monofunctional hydroxy materials with polyfunctional hydroxy materials. If present, component (E) is typically present in the composition in an amount of up to about 10% by weight, or up to about 15% by weight, or up to about 20% by weight. If present, typical ranges include from about 0 to about 20% by weight, or from about 0 to about 15% by weight, or from about 0 to about 10% by weight. The compositions of the invention can also contain suitable adjuvants such as accelerators, inhibitors or retardants, absorbers, stabilizers, pigments, dyes, surface tension depressants and wetting aids, antioxidants and other ingredients well known to those skilled in the art. The amounts and types of each ingredient in the composition must be adjusted to provide handling and physical properties before and after polymerization. For example, the polymerization rate, polymerization stability, fluidity, compressive strength, tensile strength and durability of dental material are typically adjusted in part by changing the types and amounts of polymerization initiator (s) and, if present , the filler size and particle size distribution (s). Such adjustments are typically performed empirically based on prior art experience with dental materials. Typical adjuvants include pigments, dyes and / or dyes. Examples include titanium dioxide or zinc sulfide (lithopones), red iron oxide 3395, Bayferrox 920 Z Yellow, Neazopon Blue 807 (copper phthalocyanine based dye) or Helio Fast Yellow ER. These additives can be used for individual staining of dental compositions. Additional additives that can be added include stabilizers, especially free radical scavengers such as substituted and / or unsubstituted hydroxy aromatics (eg, butylated hydroxytoluene (BHT), hydroquinone, hydroquinone monomethyl ether (MEHQ), 3,5-di- tert-butyl-4-hydroxyanisole (2,6-di-tert-butyl-4-ethoxyphenol), 2,6-di26 / 56 tert-butyl-4- (dimethylamino) methylphenol or 2,5-di-tert-butyl hydroquinone, 2- (2'-hydroxy-5'-methylphenyl) 2H-benzotriazole, 2- (2'-hydroxy-5 , -t-octylphenyl) -2H-benzotriazole, 2-hydroxy-4-methoxybenzophenone (UV-9 ), 2- (2'-hydroxy-4 ', 6 , -di-tert-pentylphenyl) -2H-benzotriazole, 2-hydroxy-4-n-octoxybenzophenone, 2- (2'-hydroxy-5'-methacryloxyethylphenyl) -2H-benzotriazole, phenothiazine and HALS (hindered amine light stabilizers), such adjuvants may optionally comprise reactive functionality so that they are copolymerized in the resin. There is absolutely no need for these adjuvants to be present, so adjuvants may not even be present. However, if they are present, they are typically present in an amount of at least about 0.01% by weight or at least about 0.5% by weight or at least about 1% by weight over the entire composition. . Adjuvants can be present in an amount of up to about 25% by weight or up to about 20% by weight or up to about 15% by weight in relation to the entire composition.

The curable composition of the invention can be obtained by combining (including mixing and kneading) the individual components of the composition, preferably under "safe light" conditions. Suitable inert solvents can be used, if desired, when supplying the mixture. Any solvent can be used that does not react appreciably with the components of the compositions of the invention. Examples of suitable solvents include acetone, dichloromethane, acetonitrile and lactones. A liquid material to be polymerized can be used as a solvent for another solid or liquid material to be polymerized. 27/56 The invention features a composition that can be cured in an acceptable period, for example, less than about 120 seconds (s) or less than about 100 s or less than about 60 s, and at a sufficient depth with the use of visible light source equipment already available at the dental office or electronics manufacturing facilities.

The person skilled in the art will appreciate that many alternative modalities of the invention can be carried out without deviating from the character and scope of the invention. Examples Except where otherwise noted, all parts and percentages are weight basis, water is deionized water, and all molecular weights are weight average molecular weight. In addition, except where otherwise noted, all experiments were conducted under ambient conditions (23 ° C; 101 kPa [1013 mbar]). In addition, almost all process steps are carried out under a dry air atmosphere: Measurements Particle size If desired, the average particle size can be determined using a commercially available granulometer (Laser Diffraction Particle Size Analysis Instrument, MASERSIZER 2000; Malvern Comp.) According to the instructions for use provided by the manufacturer. Compressive strength (CS) If desired, for the measurement of compressive strength, 6 samples of each material can be prepared and measurements can be performed according to ISO 9917 using a universal testing machine (Zwick Ζ 010), with the condition that the test samples are 3 mm x 3 mm x 5 mm 30/56 are used in combination with a traction speed of 4 mm / min. Compressive strength is typically given in [MPa]. Flexural strength (FS = flexural strength) If desired, the flexural strength measurement can be carried out according to ISO 4049, using a universal testing machine (Zwick Z 010, traction speed 1 mm / min). Flexural strength is typically given in MPa. E-Modulus (E-M.) If desired, E-M (I) can be determined in accordance with ISO 4049 and is given in [GPa]. Connected disk shrink-stretch (SHR) If desired, the shrink-stretch of the connected disk can be determined according to the Watts protocol, as described in more detail in Dent. Mater. 1991, 7, 281-287. Unity: [%]. Depth of cure (DOC - depth of cure) The curing depth (ie, curing depth) was analyzed according to ISO 4049 by packing a sample of paste in a cylindrical metal curing mold (8 mm deep, 4 mm in diameter) and curing the sample for 40 s with an ELIPAR ™ Trilight Standard (800 Molecular Weight / cm 2 ) (3M ESPE Company). The cured sample was removed from the mold and the uncured paste was removed from the sample with a plastic applicator after less than about one minute of curing. The results were reported as the average of three replicates. refractive index (rin 20 ) If desired, the refractive index can be measured with a Kruess AR 4 D device (refractometer according to the Abbe measurement principle). The refractive index is typically measured at 20.0 ° C at a wavelength of 589 nm. Viscosity (n) If desired, viscosity can be measured with a Haake RotoVisco RV1 device (rotor C60 / 1 for viscosities up to 8000 MPa.s or rotor C20 / 1 for viscosities above 8000 mPa.s together with stator P61). Viscosity is typically measured at 23.0 ° C between two flat and parallel plates (ie, stator and rotor). After system activation and rectification, the appropriate rotor is installed. The rotor is then lowered and the distance between the stator and the rotor is set to 0.052 mm (using RheoWin Pro Job Manager Software Version 2.94) for the measurement of viscosity. Then, the rotor is raised and the material to be measured is given on the stator (1.0 ml with C60 / 1 rotor or 0.04 ml with C20 / 1 rotor). Without undue delay, the rotor is lowered to the preliminary set measuring position. The material to be measured is quenched at 23.0 ° C. The shear rate for the measurement has to be adjusted to a value so that the torque is at least 5000 pNm (therefore normally the shear rates of 100, 200, 500, or 1000 s-1 31/56 are used depending on the viscosity of the material to be measured). The measurement starts and continues for 60 s. Viscosity values (Pas) are recorded starting 20 s after the start of the measurement and the average value of the recorded values is given as the viscosity. Shrinkage stress (stress) Shrinkage stress can be measured according to the Sakaguchi et al. (Dent. Mater. 1997, 13, 233-239). The irradiation of 45 mg samples was performed for 40 seconds using a 3M XL3000 irradiation device (650 molecular weight). The stress value in pstrain was recorded for 10 minutes after the beginning of irradiation. Compositions Abbreviations The name and / or structure of the components used are given in table 1.

The mixture is then heated with stirring at a temperature of about 70 ° C until the completion of the addition reaction (measured via 1HNMR: no sign of residual epoxy groups was detected). Optionally, 3 to 5% by weight of MSA are slowly added with stirring and stirring is continued for about 60 min at about 70 ° C. The mixture is then allowed to cool to room temperature with stirring. The upper phase of cyclohexane is separated from the lower viscous oily phase, if any. The separated cyclohexane phase is washed once with water, then extracted twice with 2N NaOH solution, then once washed with water, then dried with anhydrous Na 2 SO 4. After filtration, the filtrate is again filtered through of basic alumina. 100 ppm BHT and 100 ppm HQME are added to the filtrate. Then, the solvent is subjected to vacuum stripping while air is bubbled through the crude sample. General procedure 2: Reaction of a precursor like diol with epoxy components containing mixtures (for example EQ in THF) with the use of BF / THF as a catalyst For example, TCD alcohol is diluted with anhydrous THF, then BF 3 * THF is added with stirring. EO gas is added with stirring so that the temperature of the reaction mixture does not exceed about 30-40 ° C. Upon completion of the addition of EO, stirring is continued at room temperature for about 30 min. 13% by weight of the water (which refers to the sum of the proportions of the reactive educts) is added, after about 30 min with agitation 13% by weight, of the basic alumina is added, too. After about 60 min of additional stirring, 13% by weight of a solution of sodium methanolate in methanol (30% in methanol) is added. The suspension is then stirred at room temperature for about 12 h. After filtration, the solvent is subjected to vacuum stripping. General procedure 3: Reaction of a functional di-epoxy precursor with an OH acid reagent with the use of PPhg as a catalyst For example, RDGE is heated with stirring to a temperature of 80 ° C. 1000 ppm HQ, 200 ppm BHT, 200 ppm HQME, and 1000 ppm PPh 3 are added with stirring. MA is added with stirring so that the temperature does not exceed about 90 ° C. Upon completion of the addition, the reaction mixture is stirred at a temperature of about 80 ° C until the completion of the addition reaction (measured using 1H-NMR: no sign of 49/56 residual epoxy groups were detected). Toluene is added with stirring. Then, the mixture is allowed to cool to room temperature with stirring. The crude reaction mixture is extracted at least twice with 4N NaOH solution, then once washed with water, then dried with anhydrous Na 2 SO 4 . After filtration, the filtrate is again filtered through basic alumina. 100 ppm BHT and 100 ppm HQME are added to the filtrate. Then, the solvent is subjected to vacuum stripping while air is bubbled through the crude sample. Instead of the moderate PPh 3 nucleophilic catalyst, basic catalysts such as KOtBu can also be used for this addition reaction. - General procedure 4: Reaction of diol based on functional non-methacrylate intermediates and / or functional methacrylate intermediates with a functional isocyanate (meth) acrylate structural unit The corresponding, for example, TCD based on non-methacrylate functional intermediate and / or already methacrylate functional intermediate 200-640 ppm BHT and 100 ppm bismuth neodecanoate (Bi-Cat, 20% by weight, bismuth, 100 ppm pertaining to the amount of bismuth alone) are added. At a temperature of about 50 ° C for example iEM is added with stirring so that the temperature does not exceed about 55 ° C. After the completion of the addition, the reaction mixture is stirred for at least an additional 16 hours at a temperature of about 50 ° C until the completion of the addition reaction (measured using FTIR: the corrected height of the NCO band at about 2270 cm ' 1 is below 0.05). General procedure 5: Dispersions of SiO nanoparticles silanated within the diol-based monomers described using a SiO nanoparticle slurry silane procedure Dispersions of nanodimensioned silica with modified surface were prepared for example in the corresponding, for example, TCD based monomer (s). The nanodimensioned silica particles can be surface treated and dispersed within the curable resin as described in US 6,899,948 B2, incorporated herein, by way of reference. A preferred method of surface treatment and dispersant is described in example 3, column 32, lines 31 to 42, as summarized below. The desired amount of the surface modifying agent (s) is added to the methoxy propanol and mixed. This alcohol solution is added to a silica sol slowly with stirring (1-2 minutes) and maintained at a temperature of about 80 ° C for about 16 h. The modified surface silica sol is solvent exchanged by mixing the sol with the corresponding one, for example, TCD-based monomer (s) and heating the modified organic sol in an oven at about 85-90 ° C for about 4 H.
