Definitions
- the present invention relates to a dental restoration assembly.
- 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.

- a first so-called healing phase during which one or more implant (s) are integrated into the osseointegration of the patient's bone structure, and during which the particular healing element is used, as will be detailed hereinafter;
- a third phase of restoration as such, during which a final 25 'final prosthesis is placed on the implant (s) via a restoration pillar or directly on the healing element (s) via the removable support.
- the second phase can be implemented during the first phase.
- the so-called temporary prosthetic prosthesis 25 may have characteristics adapted to a definitive use and in this case the third phase is merged with the second phase.
- the healing element must necessarily be adapted for use alone in the mouth, either during the first phase or during the first two phases, but also be suitable for situations for which the addition of a prosthesis is preferred, in first, second or third phase.
- the healing element may occupy a first configuration in which it receives the removable attachment of a prosthesis support, and a second configuration in which it is fixed alone on an implant, without the addition of a prosthesis, or no other component.
- the implant 60 comprises an overall envelope of cylindrical or frustoconical shape and a longitudinal axis L forming an axis of revolution of this global envelope.
- Implant 60 includes a means anchoring in the bone structure of the patient.
- This anchoring means may be a set of threads disposed on an outer periphery of the implant and comprising a variable thread pitch.

It has the function of being lodged within the incised gingiva, after fixation of the implant, by direct or indirect fixation, preferably removable, to the implant.
- the healing element 10 comprises an upper part 31 intended to be in contact with the gingiva and a lower part 32 intended to be introduced into the opening of the implant to cooperate with the device. connection.
- the healing element comprises a through opening 1 1 oriented along an axis and intended to receive a screw 40 screwed into the threaded opening 21 of the implant.
- the healing element 10 comprises in particular an opening in a surface opposite to a terminal surface 14, which will be specified later.
- the healing element 10 is therefore intended to be fixed directly on the implant via the screw 40.
- the axis of the through opening 1 1 is confused with the longitudinal axis L of the implant. This assembly is particularly illustrated by FIGS. 18 and 21.
- the opening 1 1 through is of generally cylindrical shape and comprises, at one end of the side of the upper part, a conical seat 33.
- This conical seat 33 is intended to cooperate with a conical seat of a screw head 41 of shape complementary to form a sealed interface.
- the conical bearing surface 33 and the screw head 41 therefore have a sealing cone function.
- the healing element 10 comprises at least one thread 34 disposed at the opening 11 and capable of cooperating with a threaded portion of the screw 40 to prevent dissociation between the screw 40 and the healing element 10 by a only translational movement.
- the screw 40 comprises a non-threaded cylindrical portion between the threaded portion and the screw head 41.
- the threaded portion is intended to collaborate with the threaded opening 21 of the implant to lock in position the healing element.
- the cylindrical portion of the screw is intended to be positioned along the opening 1 1 of the healing element.
- the screw is designed so that, when the screw head 41 is in support on the conical bearing surface 33 of the healing element, the at least one thread 34 is opposite the cylindrical part of the screw.
- the threaded portion of the screw 40 can not be simultaneously engaged with the at least one thread 34 and the threaded opening 21 of the implant.
- Such an assembly of the screw also called “captive” avoids mistakenly dissociating a healing element of the screw associated with it, for example this assembly makes it possible to avoid dropping the screw by manipulating the element. healing.
- the healing element and the screw can thus be delivered pre-assembled which reduces the amount of handling for the dentist.
- the at least one thread 34 also constitutes a point of attachment of the healing element that may be used during a subsequent removal of the healing element.
- the dentist can then partially unscrew the screw so as to dissociate its threaded portion of the threaded opening 21 of the implant while retaining a catch of the threaded portion on the at least one thread 34 of the element. healing.
- the dentist can then easily grasp the screw head and pull on it to disassemble the healing element without transmitting effort to the implant and without embarrassment to the patient.
- this healing element 10 can be removably attached to a pillar base which is connected to the implant 60.
- the implant 60 is secured to the bone part, the base of pillar is fixed on the implant 60, so that its collar is positioned at the border between the bone and the gum.
- the healing element covers the abutment base to the collar, so that the gingiva is almost exclusively in contact with the healing element 10.
- the assembly formed by the assembly of the healing element on the abutment this pillar base thus corresponds to a set of healing previously described.
- the removable support for receiving a prosthesis is distinct from the healing assembly, that is to say, the two or the only component it contains.
- the removable medium does not participate in a fingerprinting function, digital or not. It is the only healing assembly, after removal or in the absence of removable support of prosthesis, which is used for the impression taking, in particular the digital impression by scanner.
- the healing element 10 comprises at its lower end and on an outer periphery a portion of hexagonal section 35, adapted to cooperate with the hexagonal section opening 22 of the implant. The interface thus formed makes it possible to ensure a fixation of the single-direction healing element 10, without rotation of the healing element around the implant 60.
- the hexagonal section portion 35 and the hexagonal section opening 22 are anti-rotation elements that could be replaced by any other equivalent anti-rotation elements.
- the healing element also comprises on the outer periphery of its lower portion 32 a frustoconical portion 36 or substantially frustoconical, adapted to cooperate with the conical bearing surface 23 of the implant to form a sealed interface between the implant and the implant. healing element.
- the frustoconical portion 36 comprises a boundary between the lower portion 32 and the upper portion 31 of the healing element.
- the conical bearing surface 23 and the frustoconical portion 36 have a sealing cone function and also a unique positioning function of the healing element with respect to the implant.
- the assembly of the conical bearing surface 23 with the frustoconical portion 36 constitutes a pivot connection of axis coincident with the longitudinal axis L.
- a connection reduces to zero any translational clearance between the healing element and the implant along the longitudinal axis L or any axis perpendicular to the longitudinal axis L.
- the connection between the healing element and the implant is a particularly rigid connection.
- the upper part of the healing element comprises an end face 14 through which opens the conical bearing surface 33 of the opening 11 and a lateral surface 13 around which the gingiva is intended to heal.
- the tapered scope is oriented towards the inside of the healing element so that the screw head 41 is embedded in the healing element.
- the screw head 41 does not protrude from the end face 14.
- the screw head 41 is arranged so as to close the opening 1 1 of the end face, while extending its surface to make a final surface Continuous, as is particularly visible in Figure 18.
- Existing implants may have different shapes including different connection devices. There may be as many different healing elements as different connection devices, in order to have, for each existing implant, a healing element with a connection device that is adapted.
- the healing element 10 has the function of being lodged within the incised gingiva, after fixation of an implant.
- the final configuration is shown in Figure 21.
- the implant 60 is secured to the bone structure 62 and emerges weakly from the bone portion in the gingiva 63.
- the healing element 10 is attached to the implant 60 so that the gingiva is almost exclusively in contact with the healing element 10.
- the healing element participates, preferably temporarily, in a restoration process, allowing the healing and the smooth production of the prosthesis final 25 'final.
- the gingiva thus heals around the lateral surface 13 of the healing element 10.
- this lateral surface 13 is chosen to best correspond to the patient's oral medium.
- the end surface 14 of the healing element is intended to remain visible above the gingival surface 64 of the gingiva, since the gingiva 63 remains in full contact with the lateral surface 13 of the healing element.
- the upper part of the lateral surface 13 and the end surface 14 thus form an emergent surface of the healing element.
- This emergent surface is particularly illustrated by FIGS. 22 to 24.
- healing elements 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 10 mm.
- Staining of the screw can quickly identify the height of the healing element. For example, a blue colored screw may be associated with the small healing element. A green colored screw may be associated with the intermediate size healing element. A red colored screw may be associated with the large healing element.
- a blue colored screw may be associated with the small healing element.
- a green colored screw may be associated with the intermediate size healing element.
- a red colored screw may be associated with the large healing element.
- the shape of the healing element is specifically chosen to promote the healing of the gingiva, according to an anatomical form corresponding best to the tooth to be replaced and therefore also to the future prosthetic vertex intended to occupy this oral space.
- 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. 18, and substantially parallel to the end surface 14.
- 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.
- FIG. 25 illustrates a top view of the upper and lower teeth
- FIG. 26 illustrates a sectional view at the level of the right-gapping plane PJ of a dentition, shown in FIG. 21, 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.
- FIG. 27 thus shows a top view of the sections of all the teeth and a top view of healing elements 10 associated with each tooth.
- the shapes of the different series of teeth numbered from 1 1 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 on the other Figures for designating the features of the invention are all approached through four different healing elements, referenced A to D.
- several healing elements among the healing elements A to D, appear suitable.
- the healing elements A are adapted to treat the restoration of the upper lateral incisors and all the lower incisors.
- the healing elements B are suitable for the restoration of the canines and premolars
- the healing elements C are suitable for restoring the intermediate molars
- the healing elements D are suitable for the restoration of the largest molars.
- the series of healing elements 10 could comprise an entirely different number of different healing elements, for example three or five different healing elements.
- healing element A is particularly illustrated by FIGS. 10A to 14A, the healing element B by Figures 10b to 14b and the healing element C in Figures 10c to 14c.
- the numerical references are not reproduced on all the healing elements of these figures, however, all these healing elements have the same characteristics, which will be described.
- the end surfaces 14 of these healing elements 10 are substantially flat and intended for positioning parallel to a plane.
- horizontal parallel to the plane of gravity PJ, between 1 and 2 mm inclusive above this plane
- They are slightly curved, however, having a central portion 145, more particularly visible in Figures 12A to 12C, intended to rise beyond the gum that its peripheral portions 146.
- the transverse section of the healing element 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 healing element (especially its projection on a plane P), which comes in its extension.
- the sections of all the healing elements 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 trapezium makes it possible to define a center 15.
- this center 15 thus defined is located on the axis of the through opening 1 1 of the healing element.
- this center 17 of the opening 1 1 at the lower end of the healing element in the alternative of a restaurant set in several distinct elements, substantially circular, it is possible defining a central axis 18 of the healing element, passing through the two central points 15, 17.
- This axis 18 of the healing element 10 is perpendicular to the end surface 14.
- the axis 18 of the Healing element whether monoblock or not, coincides with the axis of the through opening 1 1 and the longitudinal axis L of the implant.
- the three types of healing elements 10, A, B and C therefore differ in particular by the trapezoidal shape of the cross section of their Lateral surfaces 13.
- the trapezoidal shape may approach a triangular shape or a rectangular shape, or even a square shape.
- FIGS. 14A to 14C give orders of magnitude of the dimensions of these healing elements, in millimeters.
- each healing element has, with the exception of the opening 11, a continuous surface, without reliefs, and / or without hollow portion, and / or without groove, and / or without stop , and / or without asperity. This surface is convex. This stepless geometry is good for oral hygiene, reduces food buildup and plaque deposition. As a remark, when the healing element is fixed alone on an implant by means of a screw 40, the head 41 of the screw completes the end surface 14, which becomes substantially continuous, even at the level of the opening 1 1.
- this surface closed by the screw head then has substantially the property of continuous surface, without relief, and / or without hollow portion, and / or without groove, and / or without stop, and / or without asperity.
- This architecture makes optimal the use of a healing element alone.
- the seal is provided at the interface between the head 41 of screw 40 and the end surface 14.
- the series of healing elements could comprise a different number of different geometries, for example at least two.
- a single form of healing element could be suitable for all teeth.
- the transverse section of an element It may approach any polygon, such as a polygon with three, five or six sides.
- this form comprises at least one center or point perfectly defined geometrically to define a center 15, or possibly a possible axis 18 of the healing element.
- This transverse section is obtained by a cutting plane substantially parallel to the plane justogingival.
- the geometry of the visible emergent surface of the healing element 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 healing element is therefore asymmetrical with respect to a median plane containing the tangent T to the gingiva, shown in FIGS. 13A to 13C, and more specifically in FIG. 25, 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 healing element.
- the geometry of the visible emergent surface of the healing element 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 or the natural form. teeth.
- the height along the longitudinal axis of the healing element on the lingual side that is to say on the side of the inside of the mouth, may be greater than the height of the healing element on the side. from outside the mouth.
- the shape of the emergent surface of the healing element is therefore asymmetrical with respect to a plane parallel to the longitudinal axis and passing through the center 1 13 of the end surface 1 1 1.
- this asymmetry can be characterized by different forms of the healing element on either side of said plane by considering a projection of the healing element on a plane perpendicular to the longitudinal axis.
- this asymmetry can be characterized by different heights of the healing element on both sides of the plane. An example of such asymmetry is particularly visible in Figure 21.
- a circular shape for the section of a healing element is unsuitable. More generally, any plane curve having a symmetry around a point or an axis is little or not suitable for the aforementioned section of the healing element, because on the one hand, it would not be adapted to the anatomy mouth and, on the other hand, its circular orientation around this axis would no longer be identifiable. For the same reasons, the emergent and visible surface of the healing element is therefore not symmetrical with respect to at least one or even several planes parallel to its axis 18, and / or comprising this axis 18.
- perpendicular median plane is not symmetrical with respect to at least one or more planes perpendicular to the emergent surface and passing through its center 15 or including the axis 18, which we call perpendicular median planes.
- perpendicular median plane is then any plane perpendicular to the plane P and passing in the center of the geometry considered of the healing element.
- a median plane perpendicular can be defined as any plane containing the axis 18 of the healing element.
- This emergent surface of a healing element can finally take any identifiable three-dimensional shape, making it possible to recognize the healing element used and possibly to know its orientation, to fulfill a second function which will be detailed later.
- the end surfaces 14 of the healing elements are extended from their periphery 146 by the lateral surface 13 around which the gingiva heals, and which thus gives the shape of gingiva adapted to the future prosthetic vertex.
- 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 healing element and / or parallel to the longitudinal axis.
- L of the implant respectively extending the different sides 141, 142, 143, 144 of the end surface 14 of the healing element.
- 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.
- the healing element can be in plastic material, compatible with medical use, and pink, white or cream.
- the healing element can be made from a polymer material, in particular from a "PEEK" material.
- it may be metal, for example titanium, or may be zirconia.
- this healing element 10 may be made of titanium with a surface treatment made from zirconia nitride in order, in particular, to improve the visibility of this element 10 by oral scans and this, while being biocompatible.
- the healing element can be manufactured by machining and / or molding and / or adding material, in other words by 3D printing.
- healing elements thus makes it possible to promote ideal healing of the gingiva in the context of a dental restoration process because of its geometry designed in phase with the oral anatomy.
- this healing element can alternatively be totally subgingival and invisible, then made visible by intervention on the gingiva. In this case, the extreme part of the healing element will always be misnamed emergent part.
- the emergent surface of the healing element 10, formed by the end surface 14 and possibly the upper part of the lateral surface 13, can advantageously comprise at least two informative markers enabling the identification of at least two characteristics of the healing element 10 and / or indirectly the abutment base and / or the dental implant 60.
- the arrangement of such informative markers on the healing element 10 makes it possible not to resort to a technique of traditional impression taking on the implant and to reduce the time required and the complexity to then develop either the dental restoration abutment which will replace the healing element 10 and on which will be arranged the final prosthesis or the final 25 'final prosthesis which will replace the temporary prosthesis 25 temporary.
- markers are optional, because according to an alternative embodiment, the single form of the emergent surface of the healing element will be sufficient for the automatic identification of the same information, due to the specific asymmetrical shape of this emerging surface. It is therefore important to differentiate the solution with a marker in relation to the non-use of the marker:
- a marker is defined as a symbol or a form specific, dedicated to its recognition, whose only function is this recognition; the marker is typically designed specifically to be easily recognized by a scanner. It generally has no impact or negative impact on the primary healing function of the healing element;
- the alternative of the invention consists in not using a marker, but in recognizing the particular shape of the healing element, in particular its end portion, in order to deduce a desired information from it.
- the recognized form has first and foremost a main technical function of anatomic healing.
- the invention takes advantage of this anatomical nature to dispense with the marker. Recognition is more difficult with this alternative, but it has the advantage of not deteriorating the ideal form designed for healing, for the secondary purpose of forming an indicator.
- the solution of this alternative without a marker, or with less marker (compared to a solution based solely on markers), is therefore advantageous and preferred.
- the characteristics identified by the informative markers comprise one or more of: the height of the healing element 10,
- the shape of the healing element 10 in particular the shape and the dimensions of the transverse section of its lateral surface 13 or of the projection on a parallel plane of the emergent surface,
- said at least two informative markers 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 of the healing element.
- first and second characteristics related to the healing element 10 are in particular the height of the healing element 10 and / or the shape of the healing element 10, in particular the shape and the dimensions of the transverse section. its lateral surface 13 or the projection on a parallel plane of the emergent surface.
- a marker can be used to derive information on the abutment base when there is one and possibly on the implant, such as their orientation, which may be related to the orientation of the healing element.
- each informational marker belongs in particular to one of the following types:
- a negative informative marker in particular recessed in one of the surfaces of the healing element 10, particularly on its emergent surface
- a positive informative marker in particular in relief on one of the surfaces of the healing element 10, particularly on its emergent surface
- an informative marker of particular and identifiable shape formed in one of the surfaces of the healing element 10, in particular of polygonal or line shape,
- an informative marker consisting of a readable numerical value or a legible identification code such as a barcode and / or a datamatrix code.
- This marker can 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.

By being thus in the position of stress, a greater part of these fins is then arranged in the groove defined in the wall of the through opening 1 1 causing a locking of the assembly of the removable support 2f, 2g with the element 10 or even with the healing assembly formed by the implant 60 and the healing element 10.
- this locking element 20a only the removal of this locking element 20a from the through hole 19 and the through opening 1 1 allows to allow a partial disengagement of the fins of said groove.
- the locking member 20a is inserted into the through hole 19 until its second end which also passes through the through opening 11 of the healing element 10 is arranged in a housing defined in the head of the screw 41 of the screw 40 mechanically connecting the healing element 10 to the implant 60.
- the body of this element of lock 20a is then between the fins hoses that are held in the stress position.
- this locking element 20a corresponds to the screw illustrated in Figures 1H, 6C, 6D, 6K to 6M
- its first end is included in the through hole 19 and its second end is located in the through opening 1 1 of the healing element 10, in particular in the housing defined in the screw head 41 of the screw 40 mechanically connecting the healing element 10 to the implant 60.
- the through hole 19 includes a scope conical which is intended to cooperate with a conical bearing surface of the complementary shaped screw head so as to form a sealed interface.
- the tapered seat and the screw head therefore have a sealing cone function.
- an arrangement of the screw head of the screw forming this locking element 20a, at the non-threaded part 42c of the wall of the through hole 19 of the second variant of the support removable 2g corresponds to an assembly of the screw called “captive” which avoids mistakenly dissociating the removable support 2g of the screw associated with it, for example this assembly makes it possible to avoid dropping the screw by manipulating it. removable support 2g.
- the removable support 2a to 2g of these embodiments comprises the longitudinal axis A1 which extends over its entire length and which coincides with axes of revolution A2, A3, A4 of the first and second components 7a, 7b of the receiving portion 4 and the connecting portion 5.
- This axis A1 of the removable support 2a to 2g is also coincident with the axis L of the implant 60 and the axis 18 of the healing element 10.
- the removable support 2a to 2g can be made of plastic material, compatible with medical use.
- this support 2a to 2g can be made from a polymer material, in particular from a material such as "PEEK”, “PMMA” or even “POM” to facilitate retouching and bonding the top prosthesis 25, 25 'on the receiving part 4.
- a material such as "PEEK”, "PMMA” or even “POM” to facilitate retouching and bonding the top prosthesis 25, 25 'on the receiving part 4.
- it may be metal, for example titanium, or may be zirconia or ceramic.
- the removable support 2a to 2g may be manufactured by machining and / or molding and / or adding material, in other words by 3D printing.
- the locking element 20a, 20b may also be made of a polymeric material such as "PEEK" material or metal, for example titanium.
- the invention offers the possibility of making a temporary crown prosthesis in an oral cavity of a patient during the time of performing a dental restoration comprising an implant and in particular the time of healing associated with the implementation of such a restoration and this, from the support 2a to 2g which can be removably mounted on the healing element from a fastening mechanism by screwing or clipping easy enough to implement, to facilitate all operations relating to the realization of temporary and / or permanent top prostheses.
- the support 2a to 2g can be easily removed from the patient's oral cavity so that retouching or polishing operations of the crown prosthesis and / or of this support 2a at 2g can be performed or else that other operations relating to the production of final crown prostheses such as impression taking can be performed.
- this removable character allows the sole removal of the support, the healing element remaining in the mouth, fixed on an implant.
- the link between the support and the healing element may be different.
- the healing element preferably comprises a female connection part (in particular within its opening 1 1), and the support a corresponding male connection part.
- a male bonding portion on the healing element would form a terminal surface poorly adapted to remain alone in the mouth.
- the support is distinct from the healing element.
- it is suitable for direct attachment to this healing element.
- such a support 2a to 2g, and a top prosthesis 25, 25 'supported, being arranged in a jaw of a patient contributes to maintaining the adjacent teeth in position by acting as a stay between these teeth, to prevent them from converging, especially during the osseointegration phase of the implant.
- the prosthesis 25, 25 'advantageously has an opening for access to this locking element.
- such a removable support 2a to 2g makes it possible to prevent any damage to the emergent surface of the healing element, while allowing the production of a crown prosthesis.
- This is particularly advantageous in that it allows the implementation of the last dental restoration phase comprising a step of automatically identifying the geometry of the restoration pieces to be formed by means of the shape of the emerging surface of the healing element, the asymmetrical nature of which can automatically deduce information on its positioning and indirectly on the positioning and orientation of the implant.
- the removable support 2a to 2g makes it possible to preserve the epithelial attachment of the soft tissues to the transmucosal part of the healing element 10 which would otherwise be damaged by other methods implemented in the state of the technique for producing such a prosthetic vertex in the context of dental restoration implementing an implant.
- the assembly formed by a healing element 10, a support and a top prosthesis fixed on this support can also be advantageously used for the fixation of a final prosthesis.
- the invention is not limited to the embodiments described, and comprises for example combinations of components of the embodiments described above.
- the invention also relates to a restoration system, which implements the aforementioned restoration method.
- This system comprises a dental restoration assembly as described above, an impression taking element, in particular digital impression taking by scanner, and at least one calculator that uses the images from the impression taking for a recognition automatic, based on the anatomical shape of the healing assembly or alternatively by the recognition of markers, the type of healing element and indirectly the healed space and positioning of the implant.
- this system uses the restoration set in a second configuration in which a prosthesis mounted on a removable support is removed: the oral space with the only healing assembly is digitized.
