Definitions
- the present invention relates to a dental implant comprising a self-tapping threaded anchoring body elongated around an axis integral with a support head of a prosthetic element, the head comprising a neck having an annular groove surmounted by an end. connection comprising a tapered conical tenon converging towards its distal portion.
- It also relates to an assembly formed of a prosthetic element and such an implant, as well as a method of using such a set. It finds a particularly important application although not exclusive, in the field of reconstructive dental surgery making the implant undetectable from an aesthetic point of view.
- the choice of the body shape of the implant was then made because of the similarity between the tibial bone and the mandibular bone with a dense bone cortex. This density has oriented the choice on a metal mechanical logic bolt type screw nut tight. It is understood that the implant surface formed by the machined surface was then the result of the mechanical milling performed for the realization of the implant.
- the spacer compensating the thickness of the mucosa and allowing the attachment of the prosthetic element itself.
- the implant structure was therefore composed of two parts: the implant and the abutment.
- the implant using the sealing technique was formed of a honeycomb structure. It was placed in the borehole resulting from drilling, bone biology subsequently making its sealing work by healing.
- the support element of the trans- gingival was of small diameter to avoid the risk of contamination.
- the particularity of this assembly required the choice of a sealed prosthesis.
- this epithelio-connective set comprised collagen fibers oriented perpendicular to the dental structures to provide a sealed protective barrier with respect to the septic oral medium. Subsequently, it was further demonstrated that the presence of organized bacteria in the form of plaque was what actually caused inflammation of the gum.
- the fibers did not anchor on the surface of the tooth, but were circularly organized around the implant. Thus it was observed during the removal of the healing abutment, a contraction of the elastic fibers contributing to the reduction of the access port to the connection with the implant.
- the causes of bone cratering and therefore the resulting gingival resorption are not limited to the type of connection.
- FIGS. 1A, 1B, 2 and 3 of the present description show typical radiographs of prostheses on patients with various implants of the prior art, showing the partial non-reconstitution of bone at the level of the connection between bone and gum. characterizing peripheral craterization.
- radiographs IA and IB show an implant 1 at the time of laying with preparation of the reception 2 of the flange of the implant by flaring 3 (Figure IA) and after three months (Figure IB).
- a craterized bone lense 4 then appears clearly at the junction 5 between the head and the body of the implant, all around the cervical periphery of the latter.
- FIG. 2 shows another implant 6 of the prior art and the phenomenon of cratering 7.
- FIG. 3 again shows, on two implants side by side 8 and 9, the poor reconstitution of the osseous neck 10.
- the present invention aims to provide an implant, an assembly comprising an implant and a prosthetic element, and a method of using such an assembly, which responds better than those previously known to the requirements of the practice, in particular in that it authorizes excellent bone reconstitution and optimized tissue integration, while allowing great prosthetic modularity.
- exceptional bone scarring around the implant see FIGS. with a lasting result whether with a single implant 11 (bone collar 12) or with two implants 13, 14 placed side by side, with perfect reconstitution of the osseous neck both at the outer periphery 15 and between the two implants 16.
- the mucosa 19 adopts a shape 20 that perfectly marries the prosthetic crown as well as the adjacent natural teeth 21.
- the mucosa 19 also has a granite appearance identical to that of the mucosa covering said teeth, which is a clear indicator of its perfect reconstitution.
- FIG. 8B gives the radiograph of the implant 22 according to the invention, the end of the head of which appears in FIG. 8A, with its prosthesis 23.
- the bone neck 24 is perfectly reconstituted.
- the bone defect existing between the alveolar bone ridge and the implants placed in place gradually fills with the neoformed bone, the type of healing being similar, whatever the implantation conditions. .
- FIG. 10 illustrates the perfect tissue regrowth observed with the invention, with the closely spaced proximal implants, FIGS. 9A to 9C.
- the gingiva 26 is indeed perfectly reconstituted even between the implants.
- the exceptional bone response with the implant according to the invention which response also generates a very good gingival reconstitution, it is shown with reference to Figures HA and HB, on the one hand radiography (Figure HA) two implants 27 and 28, namely an implant according to the invention 27 and an implant of the prior art 28, and secondly the photograph ( Figure HB) of the corresponding gingiva.

- triple threading is a technique to have the apparent profile of a single thread while allowing screwing three times faster, since it is formed of three propellers tapped shifted by 120 °, for example not 1.8 mm, giving the impression of an apparent pitch of 0.6 mm.
- Such threading in combination with the other characteristics of the implant, generates good bone condensation and excellent primary grip even in the apical zone while allowing quick insertion.
- the conical-cylindrical shape of said body also contributes to the exceptional grip and the better locking of the implant at the end of screwing.
- the concave portion of the annular groove will now be described more specifically with reference to FIG. 13.
- the concave part more particularly described here is formed (cf figure 13) by portions of O-rings, and more particularly by their internal faces 60, 61 and 62, turned on the side of the axis 42, namely a first portion 60 of radius of curvature r2, junction with the convex ring portion and formed around a circle rotating about the axis 42 of radius R2, a second portion 61 tangent to the first and also formed by a second concave portion of the ring surface, of radius of curvature r3, rotating around a circle of radius R3 about the axis 42, and a third portion 62 of concave toroidal surface of radius of curvature r4 formed around a circle of radius R4, tangent to the second and ending on the base 58 of the tenon.
- the convex / concave curve of the cervix is a curve entirely of revolution.
- the convex part connected to the upper part of the body is ring-shaped ring simple enough, as the concave portion may itself consist of several portions of torus inverted although all of them being in the continuity of one of the other without point of inflection, can form around circles of different radii.
- FIG. 14 shows the implant 40 according to the embodiment more particularly described here, whose body 41 therefore comprises a triple thread 59.
- the frustoconical cervical portion 49 furthermore has a groove of increasing height at an angle ⁇ 1 of, for example, the cylindrical apical portion 48 having in turn a groove of increasing height, at an angle OC2 of identical value, or slightly greater at a ⁇ , for example 1.2 °.
- the taper ⁇ of the cervical portion 49 is of vertex directed towards the apical end portion 48 of the body, and of a value equal to a few degrees, for example from 6 to 8 °.
- the body 41 also terminates in the lower part by an apical apex 64, spherical of large radius and comprises three notches 65 tapping, radially distributed star with three branches.
- the notches consist of longitudinal recesses 66 formed from the apical apex 64 and delimited by two perpendicular faces 67 and 68, the latter having a lower portion 69 and a right upper portion 70 curved. Also referring again to FIG.
- the head 43 comprises, for its part, means 71 for indexing and connecting with a tool, said means 71 being formed of a protruding block on the top of the post 47, of equilateral triangular cross section having rounded vertices 72, of height h.
- This block and the frustoconical tenon 47 of the head are pierced with a conduit or axial bore 73, threaded, whose lower end 74 is located substantially halfway up the neck 44.
- the bore 73 is adapted to receive a screw 75 for fixing the prosthetic element as will be described more fully below.
- the implant may present a rough surface condition to the burial limit 76, which allows for better osseointegration, while indicating the burial limit of the burial. visually implant the surgeon.
- the material used is a biocompatible metal (Titanium for example) or a material known under the name TA6V ELI [ISO Standard 4832-3] which also corresponds to grade 5 ELI according to the ASTM classification (Titanium base alloy with 6% of Aluminum and 4% Vanadium), which again allows great biocompatibility, while ensuring high mechanical strength.
- the range of diameters 2.8; 3.5; 4; 4.5 and 5.5 mm is for example proposed, the other parameters of the product remaining unchanged, which allows standardization.
- FIGS. 15 to 18 show a range of transfers showing in FIG. 15 the upper part of the implant 40 with a removable protective ring 77 made of PEEK, said protective ring being of oval external shape for adaptation to the gingiva and comprising an internal bore of complementary shape to the pin 47 of the frustoconical head.
- the ring 77 has a lower periphery 78 in the extension or substantially in the extension of the concave curve 62 of the neck.
- FIG. 1 A prosthetic abutment phantom 79 of small height constituted in a manner known per se is shown in FIG.
- Figure 16 shows the head of the implant 40 with a healing screw 80, for example of height 2.6 mm, which is placed on the ring 77 removable protection.
- the screw is fixed inside the bore 73 (see the half-section) via the external thread 81 which will cooperate with the internal thread of the bore of the head of the implant, to allow its screwing via a tool known in itself.
- FIG. 17 shows a pillar 82 of the type used more particularly with the invention surmounted by a sheath 83.
- FIG. 18A shows an implant head 40 having in the upper part a conical abutment transfer 85 to take the impression of the implant assembly 40 and conical abutment 82 .
- Figure 18B shows the base of the implant 40, the PEEK ring 77 which supports an implant holder 86 also playing the role of impression transfer and temporary false stump.
- This is antirotational indexed on the triangle of the implant and has on its side faces marking lines 87 for example laser.
- marking lines 87 for example laser.
- a horizontal laser marking 87 'of identification of the emergence level of the healing screw 80 is also provided.
- FIGS. 19 to 22 show a range of "implant + prosthetic element” assemblies, the prosthetic elements 90, 91, 92, 93 being of the false abutment type. These are attached to the head of the implant 40 by a screw 94 (see Figure 21).
- FIG 23 shows schematically in section an implant 40 according to the embodiment of the invention more particularly described.
- the volume of the drill shown diagrammatically at 95, and used according to one embodiment of the invention, is homothetic to that of the thread base, the profile of which is shown in dashed line 96.
- the volume of the body of the implant is itself equal to the volume of the homothetic drill of equal length below the burial limit 76.
- the profile 97 of the implant which, compared to the bottom thread profile 96, makes it possible to highlight the increasing values of the depths of the threads before and after the inflection plane 98 between the cervical frustoconical zone 49 and the apical cylindrical zone 48.
- the so-called terminal drill is of a type known per se, for example a helical drill. 0.9 mm longer than the implant, provided with means of identifying the diameter for example, by color code, and a mark of the limit of depression (blackened band). Partly intraosseous and of equal length, the volume of the forest corresponds to that of the implant.
- anatomical abutments of Figures 19 to 22 are anatomically shaped corresponding to a molar 90, a premolar 91, a central incisor 92 and a lateral incisor 93.
- the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all the variants and in particular those where the angles ⁇ , ⁇ 1, ⁇ , ⁇ and ⁇ are different from the values indicated above.
