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.
