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.

Abstract: The invention relates to a dental implant comprising an intraosseous anchoring base (1) provided with means for connecting to a support pillar (2) for a prosthetic tooth, said connecting means comprising a neck (11) provided with an annular groove (10) extending upwardly by a tenon (12). Said implant is characterised in that the tenon (12), which has a conical profile, is capped in a tight manner by a homothetic borehole (20) made in the base (21) of the pillar, and carries an indexing relief (13) that can co-operate with a complementary impression in the borehole of the pillar in order to ensure the angular positioning thereof.
