Abstract

The present invention relates to a dental implant comprising an intra-bone anchorage footing which has means for fixing to a support post of a prosthetic tooth, characterized in that said fixing means comprises an internal frustoconical cavity made in the upper part of the footing of which the outer periphery has a beveled peripheral edge and the inner periphery has an indexing relief, and into which the homothetic base of said post is intended to fit.

Claims

1. A dental implant of the type comprising an implant body (1) for endosseous anchorage, said implant body (1) being provided with connection means for connection to a supporting post (2) for a prosthetic tooth, said implant being characterized in that said connection means comprise an internal frustoconical cavity (10) formed in the upper part of the implant body (1), of which the outer perimeter is provided with a chamfered peripheral edge (11) and the inner perimeter with an indexing relief (12), said cavity (10) being designed to receive, by insertion, the homothetic base (20) of said post.

2. The implant as claimed in claim 1, characterized in that said cavity (10) is continued downward by a tapped axial hole (13) designed to receive a screw (3) for fixing said post.

3. The implant as claimed in claim 1, characterized in that said indexing relief (12) consists of lateral facets defining a hexagon.

4. The implant as claimed in claim 1, characterized in that the wall of the cavity (10) is separated longitudinally from the indexing relief (12) by a circular groove (14).

5. The implant as claimed in claim 1, characterized in that said implant body (1) has a smooth upper neck (15) which laterally continues the chamfered edge (11) in the downward direction.

6. The implant as claimed in claim 5, characterized in that said neck (15) has cylindrical generatrices and is located above successively cylindrical (1a) and conical (1b) threaded portions of the implant body (1), the outside diameters of which are continuous.

7. The implant as claimed in claim 1, characterized in that the cone angle of said cavity (10) is between 7°

and 9°

.

8. The implant as claimed in claim 1, characterized in that said implant body (1) has three screw threads (F).

9. The implant as claimed in claim 1, characterized in that said post (2) has an enlarged head (24) with a lower shoulder (21).

10. The implant as claimed in claim 1, characterized in that said post (2) is provided with an internal through bore (23) in which a fixing screw (3) is housed.
