    Healing abutment for dental restoration
    The present invention relates to a healing element for dental restoration and to a method of manufacturing a dental restoration abutment based on such a healing element.
    Dental restoration makes it possible to provide artificial dentition to a partially or totally toothless patient. It is based on the integration of one or more implants in the bone structure, made by an incision of the gum in order to reach the bone structure and pierce it. Then, a healing element is generally fixed on an implant and this assembly remains untouched until the implant is secured in the bone structure by osseointegration and healing of the gum around the healing element. Dental restoration can be finalized by attaching a restoration abutment to the implant, on which the dental prosthesis is fixed. The abutment and the dental prosthesis are personalized, adapted to the patient's anatomy and to the tooth to be replaced, to achieve 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, existing methods of dental restoration face all or part of the following technical problems:
    - in many existing processes, a new intervention on the gum is carried out after its healing following the implant break, to make the impression, material or digital, of the space to be restored, while having a view of the implant and gum to take into account 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 which are not removed during an impression, in order not to strike the gum: in return, these methods use specific healing elements, in general of substantially cylindrical and standard shape and sometimes incorporating indicators and / or several complementary components to allow taking into account all or part of the geometry above the implant without having full access to it by taking an impression. These less traumatic methods then have other drawbacks, of complexity and / or less good optimization of the healing phase.
    Thus, a general object of the invention consists of a dental restoration solution which does not include all or part of the drawbacks of the state of the art.
    More specifically, a first object of the invention is a dental restoration solution which minimizes the trauma of the patient during the restoration process.
    A second object of the invention is a dental restoration solution which allows restoration that is as suitable as possible for the patient's anatomy.
    A third object of the invention is the most universal dental restoration solution possible, suitable for any implant and any restoration.
    A fourth object of the invention is the simplest possible dental restoration solution.
    To this end, the invention is based on a healing element suitable for connection with a dental implant, comprising a lateral surface intended for integration within a gum to form the gum during its healing, and a surface terminal, characterized in that a part of the lateral surface and the terminal surface (14) form an emerging surface, intended to remain outside the gum, which is asymmetrical with respect to at least one perpendicular median plane.
    The parts of the emerging surface intended respectively for positioning oriented towards the inside and towards the outside of the mouth may have a different shape.
    A cross section of its lateral surface or a projection on a parallel plane of the emerging surface can present:
    - A substantially trapezoidal shape or a substantially polygonal, or triangular, or square, or rectangular, or ovoid, or a substantially polygonal shape with rounded angles; and or
    - a part intended for a positioning oriented towards the outside of the mouth of larger dimension than a part intended for a positioning oriented towards the inside.
    Its terminal surface and / or its emerging surface may have:
    - a non-planar, curved surface; and or
    - a convex surface; and or
    - a surface without roughness.
    The healing element may be a cap which includes an opening in a surface opposite the terminal surface to cooperate with an abutment base.
    The healing element may include an anti-rotational element, in particular a groove, for fixing it with an abutment base without rotation around the abutment base.
    Its terminal surface or its emerging surface may include an indicator to indicate its height or the healing element may include a color to indicate its height.
    The healing element may be a healing abutment which includes a device for connection with an implant.
    The invention also relates to an assembly formed by the removable association of a pillar base and a cap, characterized in that the cap is a healing element as described above.
    The abutment base may include an implant connection device, and the end surface or the emerging surface of the cap may include a side parallel to a planar surface of the connection device.
    The invention also relates to a series of healing elements, characterized in that it comprises at least two healing elements as described above having different shapes, or in that it comprises at least three healing elements of different shapes.
    The invention also relates to a method of manufacturing a dental restoration abutment, intended to be fixed to a dental implant on a first end and to receive a prosthesis on its second end, characterized in that it comprises the following steps :
    - taking a manual or digital impression of the buccal space comprising a healing element as described above fixed on the implant;
    - automatic detection of implant positioning by identifying:
    the axis of the implant corresponding to an axis of the healing element identified by the geometry of its emerging surface outside the gum or from an association with a memorized healing element stored in a database, in particular from its reference entered in a man machine interface or from its automatic recognition by the shape of its emerging part;
    - orientation of the implant from the orientation of the emerging surface out of the gum or from an association with a healing element stored in a database, in particular from its reference entered in a human interface machine or its automatic recognition by the shape of its emerging part;
    - height of the implant by determining the height of the healing element, from a color or an indicator of its surface emerging from the gum or from an association with a memorized healing element in a database, in particular from its reference entered in a man-machine interface or from its automatic recognition by the shape of its emerging part.

    According to the embodiment of the invention which will be described, a dental restoration uses an intermediate component which we will call pillar base 1, which is sometimes simply called pillar or T-base or Esthetibase. The pillar base 1, particularly shown in Figures 1 to 8, comprises two main parts, separated by a flange 2. A first part comprises a connection device 3 with an implant. A second coronary part 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 furthermore intended for alignment with the axis of an implant. According to the embodiment, the anti-rotational element 6 is a lug. This anti-rotational element 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 several grooves arranged on the circumference of the pillar base 1 in the vicinity of the flange 2.
    Following the attachment of an implant during a dental restoration process, a pillar base 1 is fixed to the implant 60 by its connection device 3, and by means of a screw 61, then a cap. 10 is fixed on the second coronary part of the pillar base. This assembly is illustrated in FIG. 23. As illustrated in particular in FIGS. 3 and 7, the cap 10 comprises an opening 11 in its connection part and a hollow interior volume, allowing the insertion of the second coronary part of the base. pillar. The periphery of this opening 11 comprises a surface 12 intended to come to bear on a corresponding flat surface of the flange 2, after clipping the cap 10 on the pillar base, to reach the assembled assembly represented by FIGS. 5 to 8 and 19a to 19d.
    There are as many different abutment bases as there are connection devices different from the existing implants, in order to be able to have, for each existing implant, a pillar base provided with a connection device 3 which is adapted to it. The advantage of this approach is that it allows the entire second coronary part of the abutment bases to be preserved, from the flange 2, unchanged, whatever the implant corresponding to the abutment 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 coronary part of the abutment base is independent of the implant, uncorrelated from the implant fixation device.
    The cap 10 has the function of being housed within the incised gum, after attachment of an implant, by attachment to a pillar base connected to the implant. The gum therefore heals around the lateral surface 13 of the cap 10. For this, this lateral surface 13 is chosen to best correspond to the patient's oral environment. The end surface 14 opposite the opening 11 of the cap is intended to remain visible above the surface of the gum, since the gum remains in full contact with the lateral surface 13 of the cap. Note, the upper part of the lateral surface 13 and the terminal surface 14 therefore form an emerging surface of the cap. For this, caps of different height can be provided to adapt to different configurations of the oral geometry. As examples of implementation, three different standard heights allow a good adaptation to all situations. This height is advantageously between 3 and 7 mm. Due to the use of an abutment base which acts as an interface, the same cap 10 is thus universally suitable for all existing implants.
    According to the embodiment of the invention, the shape of the cap is specifically chosen to promote healing of the gum, according to an anatomical shape that best corresponds to the tooth to be replaced and therefore also to the future prosthesis intended to occupy this space. oral. This shape is notably characterized by the planar section of its lateral surface 13, this section being a transverse section through a plane perpendicular to the lateral surface, and substantially parallel to the terminal surface 14. In note, this section is substantially reproduced by the shape of the terminal surface 14.
    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 justa-gingival level of a dentition, at the root of the emergences of the teeth. These figures show that the teeth have sections of different shapes, which can be simplified by rectangular and / or square and / or triangular, but more specifically trapezoidal shapes.
    According to the embodiment chosen, a series of caps 10 of different shapes will allow these different shapes to be reproduced as well as possible. FIG. 11 thus represents 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 characteristics of the invention, are all approached by means of four different caps 10, referenced A to D. For certain teeth, or even all the teeth, several caps, among the caps A to D, appear suitable.
    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 the restoration of the intermediate molars then the caps D are suitable for the restoration of the larger molars. These caps will now be described in more detail. The cap A is particularly illustrated by Figures 12a to 16a, the cap B by Figures 12b to 16b, the cap C by Figures 12c to 16c and the cap D by Figures 12d to 16d. To avoid weighing down the figures, the numerical references are not reproduced on all the caps of these figures; however, all of these caps have the same characteristics, which will be described.
    As can be seen 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 plane and intended for positioning parallel to a horizontal plane ( parallel to the justagingival plane, between 1 and 2 mm inclusive above this plane) corresponding to the section plane of FIG. 9. They are however slightly convex, having a central part 145, more particularly visible in FIGS. 14a to 14d, intended to rise more beyond the gum than its peripheral parts 146.
    The transverse section of the cap, which gives the final shape to the gum 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 include a long side 141, which will be placed on the side of the outside of the mouth, a small side 142 opposite parallel, which will be placed on the side of the inside of the mouth, connected by two sides 143, 144. The crossing diagonals of the trapezoid makes it possible to define a center 15. In addition, 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 of the cap, passing through the two points central 15, 17. This axis 18 of the cap 10 is perpendicular to the terminal surface 14. The whole architecture of the pillar base and an associated cap 10 is designed so that the axis 18 of the cap corresponds to the longitudinal axis L of the abutment 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 trapezoid of the smallest cap A approaches a triangle, because its short side 142 is very small. The trapezium of the cap B approaches a rectangle, the long side of which 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 approach d 'a rectangle, 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 for the dimensions of these caps, in millimeters.
    Naturally, this substantially trapezoidal shape retained has rounded angles and curved sides, to guarantee not to strike the gum. In addition, the terminal surface 14 of each cap has a continuous surface, without reliefs, and / or without hollow part, and / or without groove, and / or without stops, and / or without roughness. This surface is convex. This uneven geometry is favorable for oral hygiene, preventing for example the accumulation of food and the deposition of dental plaque.
    Alternatively, the series of caps could include a different number of different geometries, for example at least 3, or even at least two. In a simplified variant, only one form of cap could be suitable for all the teeth.
    According to other alternative 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, even an oval section, or any other shape further away from a polygon. Advantageously, this shape comprises at least one perfectly geometrically defined center or point 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 emerging surface of the cap on the inside of the mouth differs from the geometry of the outside, to take account of the curvature of the gum. This shape of the emerging surface of the cap is therefore asymmetrical with respect to a median plane containing the tangent T to the gingiva, represented in FIGS. 15a to 15d and more precisely in FIG. 9 considering a tooth 50 to be restored. Thus, a circular shape, associated with a cylindrical cap, is unsuitable. More generally, any flat curve having symmetry around a point or an axis is hardly or not at all adapted, because on the one hand, it would not be adapted to the anatomy of the mouth and, on the other hand, its circular orientation around this axis would no longer be identifiable. For the same reasons, the emerging and visible surface of the cap is therefore not symmetrical with respect to at least one, or even several planes parallel to its axis 18 and including this axis 18, or several planes perpendicular to the emerging surface and passing by its center, which we call perpendicular mid-planes. In the example shown, only the plane perpendicular to the tangent plane T mentioned, passing through the middle of the two sides 141, 142, forms a plane of symmetry. This emerging surface of a cap can finally take any identifiable three-dimensional shape, making it possible to recognize the cap used and possibly to know its orientation.
    The end surfaces 14 of the caps are extended from their periphery 146 by the lateral surface 13 around which the gum heals, and which thus gives the form of gum adapted to the future prosthesis.
    This lateral surface 13 has several surfaces 131, 132, 133, 134, substantially planar, 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 terminal surface 14 and these different parts of the lateral surface 13 are produced by rounded surfaces, without roughness, in particular convex.
    Finally, the lateral surface 13 of the caps ends in a substantially frustoconical surface 19, up to the substantially circular opening 11 mentioned above. This opening 11 opens onto a hollow part internal to the cap 10, which allows the housing of the second coronary part of the pillar base. This hollow part is provided with a fixing device complementary to that 4 of the pillar base. In the embodiment, these are beads provided for clipping onto the grooves 5 of the pillar base. Finally, a substantially longitudinal groove 16 is arranged in this hollow part of the cap, to cooperate with the lug, thus forming a connection blocked in rotation, and perfectly indexed, the orientation of the cap being unique and perfectly imposed. Figures 3 to 8 and 17a to 17d, 18a to 18d and 19a to 19d, particularly show the assembly of a cap 10 with a pillar base 1.
    The cap may be made of plastic material, compatible with medical use, and of pink, white or cream color. Alternatively, it can be made of metal, for example titanium, or can be made of zirconia.
    The use of healing caps therefore promotes ideal healing of the gum in a dental restoration process, as has been discussed, due to its geometry designed in phase with the oral anatomy. The solution was described with a healing cap in the previous embodiment. As a variant, a solution without abutment base can be implemented, by means of a single healing element, or abutment, comprising a device for connection with an implant and a shape corresponding to the cap described above. Thus, the invention relates to any healing element, for example a cap associated with any subgingival healing screw or a pillar, which includes the characteristics of the cap described above. As a note, this healing element can alternatively be totally subgingival and invisible, then made visible by intervention on the gum to implement the rest of the recognition process which is described below.
    In addition to the advantages described above, the healing element allows the implementation of an advantageous restoration process, comprising a process for manufacturing a permanent dental prosthesis and abutment, with minimal trauma to the gum. Indeed, it is possible to obtain a digital or physical imprint of the area to be restored without removing the element of scarring in the mouth, therefore without hitting the gum.
    For this, a practitioner can take a digital impression of the patient's mouth, without removing the healing element. The scanning data, obtained by any device such as an oral scanner for example, is automatically transmitted to a computer equipped with dental restoration software. This software has a man-machine interface, by which an operator can indicate the cap model he has used, or more generally the reference of the healing element, and possibly the implant and / or the pillar base used.
    From the scanning data, software automatically determines the axis of the healing element, by geometric construction, for example from the identification of the center 15 and of the direction perpendicular to the terminal surface 14 passing through this center. 15. By this construction, he can thus automatically determine the axis of the implant, without having to view it directly.
    Then, as the geometry of the healing element corresponds to a unique positioning around its axis 18, or around the longitudinal axis L of the abutment base, to respect the oral environment and in particular the geometry of the gum towards the inside of the mouth which differs from its geometry towards the outside, it is possible to deduce from its orientation 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 automatically deduces the positioning of the implant connection device, without having to view it directly. By way of example, it is possible during this construction to require that one of the parallel sides of the trapezoidal shape of the visible surface 14 of the cap be parallel to one side of the hexagon of the device for fixing a implant.
    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 consist in forming healing elements of different colors for different heights. A second approach consists in placing any indicator on the visible surface 14 of the healing element to indicate this height, this indicator can be composed of numbers and / or letters and / or any symbol and / or colors and / or laser markings. A third approach may consist in forming healing elements having a visible surface 14 different according to their height. For example, the caps A, B, C, D could keep the same shape but with slightly larger dimensions for greater heights, thus making it possible to automatically differentiate them and then to determine their height.
    In a variant or additional embodiment, an operator enters the reference of the healing element via a man-machine interface, which allows the software to find the characteristics of this healing element such as its height, its center and / or axis, in a library in the form of a database stored in an electronic memory which it can consult. FIG. 20 illustrates by way of example a virtual 10 ’cap stored in the library associated with the restoration software. A mark in space 50 ’is associated with the cap, allowing it to be positioned in space. Alternatively, the software can automatically recognize the healing element from its geometric characteristics, without manual entry of its reference.
    From the digitized data, the software therefore knows how to associate the virtual healing element from its library with the digitized oral environment, replacing the real healing element, to obtain a more perfect digital reproduction. Note, the shape of the actual healing element makes it possible to determine its orientation, in particular because of its asymmetrical shape, as mentioned previously. As shown in FIG. 21, the real mark 50 of the real cap 10 is thus automatically determined by the software. It is possible to perfectly position the virtual healing element on the digital imprint, automatically or optionally by the intervention of an operator on a man-machine interface making it possible to view the buccal imprint and the element of healing. This perfect positioning of the virtual healing element makes it possible to deduce therefrom all the neighboring geometries, from 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 gum without the presence of the cap 10 or the pillar base, as shown in FIG. 22.
    When the restoration software has precisely repositioned the positioning of the hidden implant, it deduces from this knowledge the final geometry of the restoration abutment to be manufactured, which must be fixed to the implant and occupy the entire gingival volume defined by the healing element, then the geometry of the dental prosthesis intended to be fixed on this pillar, in a known manner.
    Note, this restoration process can be done completely digitally, therefore virtually, or include construction phases of a plastic or plaster model. In the latter case, a physical impression, for example made of silicone, can be made, a plaster can be poured into the impression to create the master model, i.e. a replica of the dental arch to be restored, which is then scanned in the laboratory to reconstruct a digital image.
