Title: DENTAL IMPLANT SOCKET WITH AN ANNULAR RECESS
Abstract:
The present invention relates to a threaded dental implant (1) intended to be screwed into a jawbone for supporting at least one abutment and/or a dental superstructure, and having a socket arrangement with a first section and a second section with respective geometrical profiles around a longitudinal center axis of the implant (1), wherein the first section is devised to cooperate with the abutment for securing the abutment in a determined position in the implant (1), wherein the second section is devised to cooperate with an insertion tool (11) for screwing the implant (1) into the jawbone, the first section comprising an annular coronal contact surface (4) on top of an opening centric at a coronal end of the implant (1), followed in an apical direction by a first tapered section (7) having a diameter decreasing in the apical direction, by a first cylindrical section (8), by first anti-rotational means and by a threaded section (1 b); the second section comprising a flat horizontal platform (6) perpendicular to the longitudinal axis and apically below the first cylindrical section (8), and further followed in an apical direction by second anti-rotational means, wherein the second section further comprises an annular retention recess (9) positioned around the longitudinal center axis and between the first cylindrical section (8) and the flat horizontal platform (6), the retention recess (9) having at least in part a diameter larger than the diameter of the first cylindrical section (8) and being adapted to engage with a retention means (12) of the insertion tool (11).
