crestal implant and method for the machining

摘要

The present invention relates to a crestal implant (1), comprising an elongate, anchoring portion (2), an implant and a blunt (4) via gear section (3), wherein the anchoring portion (2) an elongate core (5), of which a plurality of ribs (6), which form groups of fins, whereby on demübergangsabschnitt (3) one or more surfaces (11) is / are provided, which are located in the circumferential direction (u) in a radial reference distance from the central longitudinal axis, and wherein the implant (1) plastic material. It is proposed that one or more groups of fins are provided, in the case of the ribs (6.0) of the radially outer ribbed rim 18 (13) a radial distance (r₀) from the central longitudinal axis (a) of the implant (1), of the radial reference distance corresponds to at least approximately, and in that one or more groups of fins are provided, within which of the ribs of only a numerical part, or within which of the ribs of all the ribs on its radially outer ribbed rim 18 along its whole or only partial circumferential extent a radial distance from the longitudinal center axis, the larger than the radial reference distance is.
