    Design of direct load dental implantology and obtaining procedure.
    Object and field of the invention:
    The object of the present invention patent application, as its statement indicates, refers to a direct load dental implantology system. This system is mainly applicable to post-extraction procedures, however, it can be adapted to any procedure of deferred dental implantology, in addition, it guarantees a recovery of the patient in a period of time less than the current one, without compromising the effectiveness of the product. The proposed invention has as its object the fixation of the implant without the need for abrasion or machining of the maxillary bone cavidagl.

    There are many dental implantology systems, whether subperiostic or osseointegrated, cylindrical or cynical, with internal or external connection, with different surface finishes and different treatments that favor recovery.
    Dental implants for common use are generally composed of an externally threaded implant body, intended to be installed by threading into the maxillary bone, on which an incrustation or abutment core is added, intended to hold the implant body.
    The problems of the current systems are mainly two:
    a) The recovery time of the patient is very long since, the invasion that is carried out is there, in addition, not in all cases, during the recovery period the aesthetic result is that required by the patient.
    b) Since the beginning of these procedures, great improvements have been achieved, but all following the same line, that is, without rethinking the concept and not including major technical advances that have occurred in recent years and that will continue to be produced and improved this procedure.

    To cite some example, document US2013233456 refers to a metal material that has a gradient of elasticity from its external to the internal surface, detailing a thermomechanical procedure for obtaining it from various alloys of materials (composites), such as Ti-Nb , with elasticity modules (Young's module) in the errtome of 90 to 110 Gpa. Its object is to achieve a deformability (elasticity) similar to bone in the external part of the implant, in order to avoid tensions and the consequent deformation of the bone during chewing. However, the problem of fixation is solved by threading on the maxillary bone, not describing other non-invasive or abrasive alternatives.
    Detailed description of the invention:
    The invention constitutes a simplification of the current dental implantology systems. It is constituted in several parts that, together, are anatomically equal to the tooth that the patient lost and, on the other hand, dilatation of the implanted material is used to achieve a prefixation of the implant while the osseointegration occurs, which avoids having to drill the bone, as is the case with current systems, thus avoiding a greater invasion in the patient and a very long healing time.
    Next, each of the pieces involved in the assembly are described in detail: Implant, abutment and crown.
    The implant is the piece that is inserted into the alveolar cavity. With the purpose of
    to achieve osseointegration of the implant with the jaw or jaw bone, during the period of time from the intervention until the implant is fully integrated in the body, a presetting is necessary to prevent the implant from moving or falling from Your correct position. Since the objective is the minimum possible invasion in the patient, the implant is manufactured with the particular geometry of the patient's alveolar cavity; It is subjected to a thymic process of contraction by cooling and placed in the alveolar cavity. Once positioned, the heat of the body humane causes the material to dilate, thus exerting just and necessary pressure on the bone of the walls of the alveolar cavity, in order to produce a prefixing strong enough for the implant to be functional from the first moment.

    When referring to the topography of the implant, it refers to its surface, that is, the area that will be in contact with the bone of the alveolar cavity. This surface is recommended to be treated so that it has some roughness, preventing it from being polished, since it is shown that the roughness favors the osseointegration process. In this regard
    the contact surface can also be increased by means of the design distributed throughout it of small "dimples". This surface finish could be similar to the finish that a golf ball has. This finish means an improvement in adhesion since, the assembly bases its effectiveness on the pressure and friction that it generates to avoid the mobility of the implant. On the other hand they are surfaces that are treated with products
    bioactives that favor the cure of the area and the speedy recovery of the patient.
    The abutment is the unibn piece between the implant and the crown. It is internal and joins the implant by means of a rosea and the crown by means of “Click” thanks to two rings located in the middle part of the abutment and in the part near the end corresponding to the crown. On the other hand, at this same end, the design allows its placement preventing its removal thanks to the geometry with which it is designed, slightly larger in diameter at the end than in the neck.
    Given the purpose of this piece, it must be manufactured in the same material as the implant, since its objective, among others, is to prevent deterioration of the implant due to galvanic oxidation. Since both pieces are in contact with the same material, the appearance of this inebmode problem is avoided, thus ensuring that it meets all the parameters and requirements necessary to perform its function.
    In the case of the pillar, being a piece that will not interact directly with the human body, the surface finish is less important, as long as it meets the necessary tolerances and does not cause allergic reactions to the patient.
    The crown is the part of the system that fulfills the static function. Its purpose is
    be the most similar to a dental piece, both aesthetically and functionally.
    In one embodiment the crown is attached to the implant by the abutment. It has a hexagonal base that is inserted into the implant to prevent relative rotation of one another, providing optimal stability to use the implant from the first moment, without fear of possible future problems. On the other hand, by continuing with the morphology of a
    Natural tooth, allows the encla to adhere to the crown, avoiding problems of gums such as pyorrhea, as is the case with implants on the market.
    It should be noted that the joint line between the implant and the crown is within the gingival tissue, Jo that provides an aesthetic finish identical to that of a healthy tooth, avoiding possible future problems.
    In the case of the crown, as regards the selection of the material, practically the same restrictions and objectives are applied as for the implant, with one exception: In this case
    10 aesthetic finishing is also taken into account, a fundamental requirement of this system part.
    A suitable material in this case would be the bio-ceramic zirconia.
    It is interesting that the crown has a superficial finish that is closest to a natural tooth, so that it will be given the texture and brightness necessary to fulfill this aesthetic function.

    Thanks to the implantology procedure described, it is possible to manufacture the three pieces (implant, abutment and crown) in a single piece, thus constituting the implant itself with the lower part manufactured with the particular geometry of the alveolar cavity and the upper part with the geometry Particular of a dental piece.

    Preferred realization:
    In a preferred embodiment of the invention the implant can be manufactured by traditional methods, with materials such as titanium, zirconium oxide or others with thermal expansion coefficients between 8 and 15 pstrain / ° C (from 0.8 to 5.5 mm / 100 ° C approximately). Given the development of the incipient 3D technology, its manufacturing can be considered through 3D printing, since titanium is a material that allows this process, thus avoiding impurities derived from the necessary welding by other procedures. Another advantage to take into account is that thanks to 3D printing you can get my complex geometries.
    The procedure for obtaining dental implantology consists in manufacturing the implant in its lower part with the particular geometry of the patient's alveolar cavity, according to some of the described technologies, already known; subsequently it is subjected to a thermal contraction process by cooling, immersing it in liquid nitrogen, for example; finally it is positioned in the alveolar cavity. Once placed, the own
    The heat of the human body causes the dilate material, thus exerting the necessary pressure on the bone of the walls of the alveolar cavity, in order to produce a fixation strong enough so that the implant is functional from the first moment. The assembly of the abutment and crown once the implant is fixed does not represent any difficulty., Implant, abutment and crown can even be configured in one piece, since the fixation is a relatively rapid process, once the body temperature has been reached. In the latter case, it is the assembly that is subjected to the thermal process described, as the implant forms a single piece with the lower part manufactured with the particular geometry of the alveolar cavity and the upper part with the particular geometry of a dental piece.

    The abutment can be a standard part within the set, which can be developed in several sizes, according to the dental piece to be replaced. This piece can be manufactured through a more traditionally industrial process in order to reduce costs.
    The crown could also be obtained by 3D printing, although the main problem it poses is that the piece, once printed, must be cooked to obtain the necessary hardness properties, which implies an added cost. As long as 3D printing does not achieve the necessary quality and precision standards, the preferred manufacturing process, instead of being additive, will be by subtraction of material by machining by milling a block of material.
    It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom.
