    Healing element for a dental restoration
    The present invention relates to a healing element for a dental restoration and to a healing assembly comprising such a healing element. It also relates to a method of manufacturing a dental restoration abutment and / or a prosthesis based on such a healing element.
    The dental restoration makes it possible to perform an artificial dentition for a partially or totally edentulous patient. It is based on the integration of one or more implants in the bone structure, made by incision of the gum to reach the bone structure and pierce it. Next, a healing element is generally attached to an implant and this assembly remains untouched until the implant is secured to the bone structure by osseointegration and healing of the gingiva around the healing element. The dental restoration can be finalized by fixing a restoration abutment on the implant, on which is fixed the dental prosthesis, or alternatively fixing a dental prosthesis directly on the implant. The abutment and the dental prosthesis are personalized, adapted to the anatomy of the patient and the tooth to be replaced, to reach a result as close as possible to the ideal natural dentition. For this, the precise volume of the space to be restored is generally taken into account, by taking an impression, which allows the personalized manufacture of the dental prosthesis.
    In the state of the art, the existing methods of dental restoration face all or some of the following technical problems: in many existing methods, a new intervention on the gingiva is performed after its healing after the implant pause , to realize the impression, material or digital, of the space to be restored, while having a view of the implant and the gum to take into account precisely all of this geometry, in order to make a pillar and a prosthesis of precise shapes: this approach is naturally traumatic; other existing methods limit this trauma by using healing components that are not removed during an impression, so as not to hit the gum: in return, these methods use particular healing elements, generally cylindrical and standard shape and sometimes incorporating complementary components to allow taking into account all or part of the geometry above the implant without having full access by taking an impression. These less traumatic methods then have other disadvantages, complexity and / or less good optimization of the healing phase.
    Thus, a general object of the invention is a dental restoration solution which does not include all or part of the disadvantages of the state of the art.
    More specifically, a first object of the invention is a dental restoration solution that minimizes trauma to the patient during the restoration process.
    A second object of the invention is a dental restoration solution which allows a restoration as adapted as possible to the anatomy of the patient.
    A third object of the invention is a dental restoration solution as universal as possible, suitable for any implant and any restoration.
    A fourth object of the invention is a dental restoration solution as simple as possible. For this purpose, the invention is based on a healing element suitable for connection with a dental implant, comprising a lateral surface intended for integration within a gingiva to shape the gingiva during its healing, and a surface terminal, characterized in that a part of the lateral surface and the terminal surface form an emergent surface, which is asymmetrical with respect to at least one perpendicular median plane and in that the emergent surface comprises at least two informative markers allowing identifying at least two characteristics of said healing element and / or a pillar base and / or said dental implant to which it would be connected.

    The end surface of the healing element and / or its emergent surface may have: a non-planar, curved surface; and / or a convex surface; and / or a smooth surface outside the informative markers; and / or a surface without opening opening.
    Said characteristics identified by the informative markers may comprise one or more of: the height of the healing element, the shape of the healing element, in particular the shape and the dimensions of the transverse section of its lateral surface or the projecting on a parallel plane of the emergent surface, the dimensions of the connecting portion of the healing element with a pillar base, and indirectly of a dental implant, the orientation of said dental implant, via the orientation of the healing element.
    Said at least two informative markers may comprise a first type of informative marking of a first characteristic of the healing element and a second type of informative marking of a second characteristic distinct from the healing element.
    Each informative marker may belong to one of the following types: a negative information marker, in particular hollowed in one of the surfaces of the healing element, a positive informative marker, in particular in relief on one of the surfaces of the cicatrisation element, an informational marker of particular and identifiable shape formed in one of the surfaces of the healing element, in particular of polygonal or line shape, an informative marker consisting of a readable numerical value or a code of legible identification such as a bar code or a datamatrix code, an RFID chip. The invention also relates to a series of healing elements, characterized in that it comprises at least two healing elements as previously described having different shapes, or in that it comprises at least three healing elements of different forms.
    Said at least two or at least three healing elements may have different heights between them and / or have transverse sections of their lateral surfaces or projections on a parallel plane of their end surfaces different from each other. The invention also relates to a healing assembly suitable for connection with a dental implant during a healing phase of a dental restoration process, characterized in that it comprises a healing element as described previously intended for at least partially surrounded by a gingiva and a pillar base for attachment in an implant, the abutment base comprising a longitudinal axis over its entire length adapted to align with the axis of said implant.

    Figures 25 and 26 show two schematic views of a sectional gingiva within which is fixed a healing assembly according to the embodiment of the invention.
    The restoration method according to the embodiment of the invention thus comprises two phases, as explained above: a first so-called healing phase during which one or more implant (s) are integrated into the bone structure of the patient by osseointegration, and during which a particular healing cap associated with a pillar base are used, as will be detailed later, then a second restoration phase as such, during which a definitive prosthesis is placed on the implant or implants by through a restoration pillar.
    According to the embodiment of the invention which will be described, a dental restoration uses, in the first phase of healing, an intermediate component that we will call pillar base 1, which is sometimes called simply pillar or T-base or Esthetitase. The pillar base 1, particularly shown in Figures 1 to 8, comprises two main parts, separated by a flange 2. A first portion comprises a connection device 3 with an implant. A second coronal portion is intended to receive a healing cap 10. For this, it comprises a connection device 4 with such a cap. According to the embodiment, this connection device 4 comprises a clipping element 5 and an anti-rotational element 6, to prevent the cap from rotating around the longitudinal axis L of the pillar base 1, this longitudinal axis L being further intended for alignment with the axis of an implant. According to the embodiment, the anti-rotational element 6 is a lug. This anti-rotational member 6 is further aligned with a particular surface of the connection device 3 with an implant. In addition, according to the embodiment, the clipping element 5 is formed by a plurality of grooves arranged on the circumference of the pillar base 1 in the vicinity of the flange 2. Advantageously, the clipping element 5 is such that it makes it possible to obtain an audible click when fastening by clipping a healing cap 10.
    Note that the pillar base 1 used is not definitive, participates in the first healing phase only, is preferably removed during the finalization of the restoration and replaced by a final restoration pillar (which may be in the form of another base). Alternatively, the same pillar base 1 is optionally removed, cleaned and reused in the final restoration, then fulfilling the second restoration pillar function.
    In addition, the pillar base 1 is preferably universal, and has a symmetrical or more precisely quasi-symmetrical shape (the antirotational element forms, for example, an exception to the symmetry) about a longitudinal axis L which forms an axis of revolution. This axis L thus forms, in particular, a central axis of symmetry of the connection device 3 with an implant. Advantageously, this same axis L also forms an axis of symmetry of the connection device 4 with a cap. The pillar base 1 thus extends generally in a single direction, identified by a longitudinal axis L only. We can therefore more generally consider that the abutment base comprises a longitudinal axis L which extends over its entire length, so as to align with the axis of an implant 60. In particular, the two connection devices 3 , 4 of the pillar base 1 are arranged at different levels around the same longitudinal axis L.
    Following the fixation of an implant 60 during a dental restoration process, a pillar base 1 is fixed on the implant 60 by its connection device 3, and by means of a screw 61, then a cap 10 is attached to the second coronal portion of the abutment base. This assembly is illustrated by FIGS. 23 and 24. As illustrated in particular by FIGS. 3 and 7, the cap 10 comprises an opening 11 to form a connecting portion and a hollow interior volume, intended for the insertion of the second coronal portion. of the pillar base. The periphery of this opening 11 comprises a surface 12 intended to rest on a corresponding flat surface of the flange 2 of the pillar base, after clipping of the cap 10 on the pillar base, to reach the assembled assembly shown. by Figures 5 to 8 and 19a to 19d.
    There are as many different abutment bases as connection devices different from existing implants, in order to be able to have, for each existing implant, a pillar base with a connection device 3 that is adapted to it. The advantage of this approach is that it allows to keep the entire second coronal portion of the pillar bases from the collar 2, unchanged, regardless of the implant corresponding to the pillar base. Naturally, it is also possible to provide different second coronary parts for different pillar bases, depending on their intended use. In all cases, the second coronal part of the abutment base is independent of the implant, decorrelated from the implant fixation device.
    The cap 10 has the function of being housed within the incised gingiva, after fixation of an implant, by fixation, preferably removable, on a pillar base connected to the implant. The final configuration is shown in FIG. 24. In this configuration, the implant 60 is secured to the bone portion 62, the pillar base 1 is fixed on the implant 60, so that its collar 2 is positioned at the level of the border between the bone portion 62 and the gingiva 63. The cap 10 covers the pillar base 1 to the flange 2, so that the gum 63 is almost exclusively in contact with the cap 10. The assembly formed by the assembly of a cap on a base of pound and corresponds to a set of healing, which temporarily participates in the restoration process, allowing the healing and smooth production of the final prosthesis, as will be detailed later .
    The gingiva 63 thus heals around the lateral surface 13 of the cap 10. For this, this lateral surface 13 is chosen to best match the oral medium of the patient. The end surface 14 opposite the opening 11 of the cap is intended to remain visible above the gingival surface 64 of the gingiva 63, or at least partially visible, since the gingiva remains mainly in contact with the lateral surface 13 of the cap. . As a remark, at least a portion of the end surface 14 and possibly an upper part of the lateral surface 13 thus form an emergent surface of the cap. This emergent surface is particularly illustrated by Figures 25 and 26. For this, caps of different height can be provided to adapt to different configurations of the oral geometry. As exemplary embodiments, three different standard heights allow a good adaptation to all situations. This height is advantageously between 3 and 7 mm. Because of the use of a pillar base which acts as an interface, the same cap 10 is thus universally adapted to all existing implants.
    According to the embodiment of the invention, the shape of the cap is specifically chosen to promote the healing of the gingiva, in an anatomical form corresponding best to the tooth to be replaced and therefore also to the future prosthesis intended to occupy this space oral.
    This shape is particularly characterized by the flat section of its lateral surface 13, this section being a transverse section by a perpendicular plane P to the lateral surface 13, shown in FIG. 23, and substantially parallel to the end surface 14. In note, this section is substantially reproduced by the shape of the end surface 14, or more precisely by the projection of this end surface 14 on such a perpendicular plane, that is to say substantially parallel to the gingival surface 64.
    To understand the approach adopted, FIG. 9 illustrates a top view of the upper and lower teeth and FIG. 10 illustrates a sectional view at the level of the right-gapping plane PJ of a dentition, represented in FIG. 24, at the level of the root of emergence of teeth. These figures show that the teeth have sections of different shapes, which can be simplified by rectangular shapes and / or square and / or triangular, but more precisely trapezoidal.
    According to the embodiment chosen, a series of caps 10 of different shapes will make it possible to best reproduce these different shapes. Figure 11 thus shows a top view of the sections of all the teeth and a top view of caps 10 associated with each tooth. The shapes of the different series of teeth, numbered from 11 to 18, from 21 to 28, from 31 to 38 and from 41 to 48 in this figure, these numbers should not be confused with the numerical references used elsewhere in the other figures to designate the features of the invention, are all approached through four different caps 10, referenced A to D. For some teeth, or all teeth, several caps, among the caps A to D, appear suitable.
    As will be detailed below, a healing element object of the invention may indifferently correspond either to the assembly formed by a pillar base and by one of the series caps fixed on the pillar base to the opposite of its connection to the dental implant, or to a unitary healing element directly attached to the dental implant 60 without use of the abutment base.
    Thus, more generally, a series of healing elements will be such that the healing elements that compose it have different heights between them and / or have transverse sections of their lateral surfaces 13 or projections on a parallel plane of their emergent or terminal surfaces different from each other.
    Within the same series of healing elements, the transverse sections of the lateral surfaces 13 or the projections on a parallel plane of their emergent or terminal surfaces 14 are each of: a substantially trapezoidal shape or a substantially polygonal or triangular shape or square, or rectangular, or ovoid, or a substantially polygonal shape with rounded corners, or cylindrical.
    In the embodiment chosen and illustrated in FIG. 11, the caps A are adapted to treat the restoration of the upper lateral incisors and all the lower incisors. The caps B are suitable for the restoration of the canines and premolars, the caps C are suitable for restoring the intermediate molars and then the caps D are suitable for the restoration of the largest molars. These caps will now be described in more detail. The cap A is particularly illustrated in FIGS. 12a to 16a, the cap B in FIGS. 12b to 16b, the cap C in FIGS. 12c to 16c and the cap D in FIGS. 12d to 16d. In order not to weigh down the figures, the numerical references are not reproduced on all the caps of these figures; however, all these caps have the same characteristics, which will be described.
    As is apparent from FIGS. 12 and 15, the end surfaces 14 of these caps 10 (A to D), intended for positioning above the gingival emergence, are substantially planar and intended for positioning parallel to a horizontal plane ( parallel to the plane just-gingival PJ, between 1 and 2 mm included above this plane) corresponding to the section plane of Figure 9. They are however slightly curved, having a central portion 145, more particularly visible in Figures 14a at 14d, intended to rise further beyond the gum than its peripheral parts 146.
    The transverse section of the cap, by a plane P perpendicular to its lateral surface 13, as explained above, which gives the final shape to the gingiva after healing, is substantially reproduced by the end surface 14 of the cap, which comes in its extension. The sections of all the caps all have a substantially trapezoidal shape. They comprise a large side 141, which will be arranged on the outside side of the mouth (vestibular side), a small parallel opposite side 142, which will be arranged on the side of the inside of the mouth (lingual side), connected by two sides 143, 144. The crossing of the diagonals of the trapezoid makes it possible to define a center 15. Furthermore, by considering the center 17 of the substantially circular opening 11 of the opposite surface of the cap 10, it is possible to define an axis 18 central axis of the cap, passing through the two central points 15, 17. This axis 18 of the cap 10 is perpendicular to the end surface 14. The entire architecture of the pillar base and a cap 10 associated is designed so that the axis 18 of the cap corresponds to the longitudinal axis L of the pillar base, and to the axis of the implant.
    The four types of caps 10, A, B, C and D, therefore differ in particular by the trapezoidal shape of the transverse section of their lateral surfaces 13. The trapezium of the smaller cap A approaches a triangle because its small side 142 is very small. The trapezium of the cap B approaches a rectangle, whose long side goes from the outside of the mouth towards the inside, and corresponds to the sides 143, 144. On the contrary, the trapezoids of the caps C and D are close to a rectangle, or even a square, whose long side is in the opposite direction, and corresponds to the sides 141, 142, which are of close length but slightly different. By way of exemplary embodiments, FIGS. 16a to 16d give orders of magnitude of the dimensions of these caps, in millimeters.
    Naturally, this substantially trapezoidal shape retained has rounded corners and curved sides, to ensure not to hit the gum. In addition, the end surface 14 of each cap, ignoring the markers arranged on this surface and which will be described later, has a continuous surface, without reliefs, and / or without hollow portion, and / or without groove, and / or or without stop, and / or without asperity. This surface is convex. In particular, it does not have a hollow shape, and naturally no opening opening (through), as would be necessary if it were chosen to secure the cap by a fixing screw. This stepless geometry is favorable to oral hygiene, for example prevents the accumulation of food and the deposit of dental plaque.
    As a variant, the series of caps could comprise a different number of different geometries, for example at least three or even at least two. In a simplified embodiment, a single form of cap could be suitable for all teeth.
    According to other embodiments, the cross section of a cap at its lateral surface 13 could approach any polygon, such as a polygon with three, five or six sides. Alternatively, the angles of these polygons could be so rounded that the overall shape would approach an oblong shape, or even ovoid section, or any other form further from a polygon. Advantageously, this shape comprises at least one center or point perfectly defined geometrically to define a center 15, or even a possible axis 18 of the cap, this center being advantageously, but not necessarily, in alignment with the longitudinal axis L of the pillar base.
    According to the embodiment, the geometry of the visible emergent surface of the hood on the side of the inside of the mouth differs from the geometry on the outside, to take into account the curvature of the gingiva. This form of the emergent surface of the cap is therefore asymmetrical with respect to a median plane containing the tangent T of the gingiva and passing through the center of the cap, said median tangent plane; this tangent T (and therefore the projection of the median tangent plane) is shown in Figures 15a to 15d and more precisely in Figure 9 by considering a tooth 50 to restore. This median plane, called the tangent plane T, is parallel to the tangent T at the gingiva, perpendicular to the justogingival plane PJ, passes in the middle of a cap.
    Thus, a circular sectional shape for the section of the cap, associated for example with a cylindrical cap, is unsuitable. More generally, any flat section having a symmetry around a point or an axis is little or not suitable for the aforementioned section of the cap, because it would not be adapted to the anatomy of the mouth. For the same reasons, the emergent and visible surface of the cap, in particular the end surface 14, is therefore generally not symmetrical with respect to at least one or even several planes comprising its axis 18. It is not symmetrical by relative to at least one or more planes perpendicular to the end surface 14 and passing through its center 15. We will call perpendicular median plane a plane corresponding to a definition given above. Such a plane is substantially perpendicular to the end surface 14 of the healing element, and thus also substantially perpendicular to the just-gingival plane forming the final surface of the gum, from which the teeth emerge. It passes in the center of the end surface 14. Alternatively, a perpendicular median plane may be defined as any plane containing the axis 18 of the cap. In the example shown, particularly visible in Figures 15a to 15d, only the median plane perpendicular to the tangent plane T mentioned, passing in the middle of the two sides 141, 142, forms a plane of symmetry.
    The end surfaces 14 of the caps are extended from their periphery 146 by the lateral surface 13 around which the gingiva is mainly healed, and which thus gives the shape of the gingiva adapted to the future prosthesis. This lateral surface 13 has several surfaces 131, 132, 133, 134, which are substantially flat, possibly slightly curved, extending in a direction substantially parallel to the axis 18 of the cap and / or parallel to the longitudinal axis L of the pillar base, respectively extending the different sides 141, 142, 143, 144 of the end surface 14 of the cap. The interfaces between the end surface 14 and these different parts of the lateral surface 13 are formed by rounded, smooth surfaces, in particular convex surfaces.
    Finally, the lateral surface 13 of the caps terminates in a substantially frustoconical surface 19, to the substantially circular aperture 11 mentioned above. This opening 11 opens on a hollow portion internal to the cap 10, which allows the housing of the second coronal portion of the pillar base. This hollow portion is provided with a fixing device complementary to that 4 of the pillar base. In the embodiment, these are beads intended to snap on the grooves 5 of the pillar base. Finally, a substantially longitudinal groove 16 is arranged in this hollow portion of the cap, to cooperate with the lug, thereby forming a connection locked in rotation, and perfectly indexed, the orientation of the cap being unique and perfectly imposed. FIGS. 3 to 8 and 17a to 17d, 18a to 18d and 19a to 19d show in particular a healing assembly according to the invention, formed by assembling a cap 10 with a pillar base 1.
    The cap may be formed of a plastic material, compatible with medical use, and pink, white or cream in color. Alternatively, it may be metal, for example titanium, or may be zirconia. The use of healing caps therefore makes it possible to promote ideal healing of the gingiva in a dental restoration process, as has been discussed, because of its geometry designed in phase with the oral anatomy. The solution has been described with a removable healing cap and distinct from a base in the previous embodiment. As a remark, this healing element may alternatively be totally subgingival and invisible, then made visible by intervention on the gingiva to implement the remainder of the recognition process which is described below. In this case, the extreme part of the hood will always be misnamed emergent part. The cap 10 will also be more generally referred to as a "healing element" 10 thereafter.
    For each healing cap 10 as described above, the emergent surface, formed by the end surface 14 and possibly the upper part of the lateral surface 13, advantageously comprises at least two informative markers enabling the identification of at least two characteristics of the healing cap 10 and / or indirectly the abutment base 1 and / or the dental implant 60. The arrangement of such informative markers on the healing cap 10 makes it possible not to resort to a technique of traditional footprint on the implant and reduce the time required and complexity to then develop the dental restoration pillar that will be placed in place of the healing cap 10 and the pillar base 1, and on which will be arranged the final prosthesis.
    According to one embodiment, the characteristics identified by the informative markers comprise one or more of: the height of the healing cap 10, the shape of the healing cap 10, in particular the shape and the dimensions of the transverse section of its lateral surface 13 or the projection on a parallel plane of the emergent surface, the dimensions of the connecting portion of the healing cap 10 with the abutment base, and therefore indirectly the dental implant 60, the orientation of the implant dental 60, via the orientation of the cap, for example by a marker aligned with an antirotational element of the cap, for example the groove 16.
    According to a particular embodiment, said at least two informative markers comprise a first type of informative marking of a first characteristic of the healing cap 10 and a second type of informative marking of a second characteristic of the healing cap 10. These first and second characteristics related to the healing cap 10 are in particular the height of the healing element 10 and / or the shape of the healing cap 10, in particular the shape and the dimensions of the transverse section of its lateral surface 13 or the projection on a parallel plane of the emergent surface. Indirectly, a marker can be used to derive information on the abutment base and possibly on the implant, such as their orientation, which may be related to the orientation of the cap.
    As this is not limiting as to the freedom of design of informative markers, each informative marker belongs in particular to one of the following types: a negative informative marker, especially hollowed in one of the surfaces of the healing cap 10, particularly on its emergent surface, a positive informative marker, in particular embossed on one of the surfaces of the healing cap 10, particularly on its emergent surface, an informational marker of particular and identifiable shape formed in one of the surfaces of the healing cap 10, in particular of polygonal or line shape, an informative marker constituted by a readable numerical value or by a legible identification code such as a barcode and / or a datamatrix code. This marker may be composed of numbers and / or letters and / or any symbol and / or colors and / or laser markings; an informative means consisting of an RFID chip.
    As a remark, the geometrical considerations described above for characterizing the healing element are true while ignoring the informative markers. For this reason, these markers 70 are not illustrated in the figures, with the exception of FIGS. 14c, 15c, 23, 24 and 26, so as not to weigh them down. However, they are present on all caps. By way of example, the characterization of the negative information marker, which is for example a simple hole, is for example its position relative to the rest of the cap 10 in which it is formed, its size, its shape or the number of such markers. negative information. These characteristics of each negative informative marker precisely make it possible to characterize the characteristic of the healing cap 10 and / or of the pillar base 1 characterized by the negative informative marker (s), such as, for example the height of the healing element. It can for example be deduced therefrom the position in height of the pillar base 1.
    Still by way of example, these same characteristics can be deduced from the characterization of the positive informative marker, which is for example its position relative to the rest of the cap 10 in which it is formed, its size, its shape or the number of such positive informative markers. These characteristics of each positive informative marker make it possible to characterize the characteristic of the healing cap 10 and / or of the abutment base 1 and therefore of the dental implant 60 characterized by the informative marker (s) positive (s).
    Another example of such informative markers of particular and identifiable shapes is a notch formed directly in the healing cap itself. The joint presence of two such notches and the distance between them can serve to indicate, for example, the position and the type of abutment base and the relation of the dental implant 60. A third example of such informative markers of particular and identifiable shapes is a line, such as an engraving or a relief, integral with the healing cap 10. The size, the position of this line and / or the number of such lines can serve to characterize an additional characteristic of the healing cap 10 and / or of the pillar base 1 and thus of the dental implant 60.
    In general, the manufacture of a dental restoring pillar, intended to be fixed on the dental implant 60 on a first end and to receive a prosthesis on its second end, comprises the following steps: the production of a physical impression or digital of the oral space comprising a healing element as described above and fixed on the dental implant 60, for example one of the caps 10 of the series, the automatic determination, from this fingerprint and informative markers of the healing element, the oral space of the abutment base 1 and thus the positioning of the dental implant 60.
    In addition to the advantages described above, the healing element allows the implementation of an advantageous restoration process, comprising a method of manufacturing a dental prosthesis and a final abutment, with minimal traumatization of the gingiva. Indeed, it is possible to obtain a digital or physical impression of the area to be restored without removing the healing element in the mouth, so without hitting the gum. Thus, in addition to its first healing function, detailed above, the cap performs a second function during the restoration process, allowing the advantageous definition of the shape of the restoration abutment and / or the prosthesis before removal. This function is complementary to its first healing function since it allows not to traumatize the gingiva after healing in a chosen anatomical advantageous shape.
    For this, at the end of the healing phase of the dental restoration process, a practitioner can take a digital impression of the patient's mouth, without removing the healing element (the cap). Scanning data, obtained by any device such as an oral scanner, is automatically transmitted to a computer with dental restoration software. This software is equipped with a human machine interface, by which an operator can indicate the model of cap he has used, or more generally the reference of the healing element, and possibly the implant and / or the pillar base used. The informative markers may be indicated to the software by the operator himself or automatically identified by the software by any means of detection, recognition and identification adapted according to the nature of the marker and its characterization. From the scanning data and the informative markers, a software automatically determines the axis of the healing element, by geometric construction, for example from the identification of the center of the cap and the direction perpendicular to the surface. terminal 14 passing through this center 15, then its orientation and the space it occupies, using the markers. He can thus in particular automatically determine the axis of the implant, without having to see it directly. Indeed, the healing element is advantageously aligned with the implant, its axis thus being coincident with that of the implant.
    Indeed, it is possible to deduce from informative markers the orientation of the axis of the connection device with the implant, for example the connection device 3 of the abutment base with the implant: this makes it possible to automatically deduce the positioning of the connection device of the implant, without having to visualize it directly, from the knowledge of the pillar base.
    Finally, in the case where healing elements of different height exist, it remains to determine this height, to perfectly position the invisible implant. A first approach may be to form differently colored healing elements for different heights. A second approach is to predict and identify at least one informative marker on the healing element to indicate this height.
    As an alternative or additional embodiment, an operator grasps the reference of the healing element via a man-machine interface, which enables the software to retrieve certain characteristics of this healing element, in confirmation or in addition to those obtained by the markers. , like its height, its center and / or axis, in a library present in the form of a database stored in an electronic memory that it can consult. Figure 20 illustrates by way of example a virtual cap 10 'stored in the library associated with the restoration software. A mark in the space 51 'is associated with the cap, allowing its positioning in the space. Alternatively, the software can automatically recognize the healing element from its informative markers, or its other geometric characteristics, without manual entry of its reference. An operator can assist a software to the correct positioning of the mark 51 of the actual cap, that is to say to the recognition of its actual positioning, by capturing on an image obtained by the scanning step mentioned above and presented to the operator on a screen of a man-machine interface one or more points of the emergent surface. From the digitized data, and possibly the help of the point (s) of the surface of the healing element manually filled in by an operator, the software thus knows how to associate the virtual healing element resulting from its library to the environment digitized mouth, replacing the actual healing element, for a more perfect digital reproduction. As shown in Fig. 21, the actual mark 51 of the actual cap 10 is thus automatically determined by the software. It is possible to perfectly position the virtual healing element on the digital impression, automatically or possibly through an intervention of an operator on a human machine interface to visualize the mouth impression and the element of healing. This perfect positioning of the virtual healing element makes it possible to deduce all the neighboring geometries, from the known references stored in the database associated with the precise healing element considered, including the position of the implant 60 and the geometry of the healed gingiva without the presence of the cap 10 nor of the abutment base, as represented by FIG. 22. In a variant, the markers used are sufficient to provide the data necessary for the correct positioning of the cap without resorting to a library.
    In any case, when the restoration software has accurately repositioned the positioning of the hidden implant, it deduces from this knowledge the final geometry of the restoration pillar to be manufactured, which must be fixed to the implant and occupy the entire volume. gingival defined by the healing element, then the geometry of the dental prosthesis intended to be fixed on this pillar, in known manner.
    As a remark, this restoration process can be done totally numerically, so virtually, totally or partially automated, or include phases of construction of a plastic model or plaster. In the latter case, a physical impression, for example made of silicone, can be performed, a plaster can be cast in the impression to create the master model, ie a replica of the dental arch to be restored, which is then scanned in the laboratory to reconstruct a digital image.
    As is apparent from the description above, the last phase of the restoration process is therefore based on a restoration device, which comprises a central processing and control unit, here comprising at least one microprocessor, linked to an electronic memory, on which software is executed to implement all or part of the steps of the restoration process described above. This central unit is linked by a communication device to a digital data acquisition module representing all or part of a dentition of a patient, which may consist of an appliance such as an oral scanner. It is also linked to a man-machine interface, comprising for example a screen and / or a keyboard, to allow exchanges with an operator, as explained above. The central unit then performs all necessary processing, calculations and other, by a software means. It is finally able to generate and transmit manufacturing orders to a device for manufacturing a restoration and / or prosthesis pillar. It can also be linked by a second communication device to a manufacturing device such as a machine tool.
