Crestal Implant And Method For Processing Same

A crestal implant, comprising an elongate anchoring portion extending in a longitudinal direction, an implant stump, and a transition portion between the anchoring portion and the implant stump, the anchoring portion having an elongate core from which a plurality of ribs extend that are distributed in the longitudinal direction and in the peripheral direction, one or more surfaces being provided at the transition portion, which surface or surfaces extend in the peripheral direction at least in certain peripheral portions at a radial reference distance from the geometrical longitudinal center axis, and the implant containing plastics and in particular consisting of plastics, characterized in that the ribs form rib groups, each of which comprises a plurality of ribs that are arranged distributed on the core periphery at a common core cross-section, that one or more rib groups are provided in which, for all ribs, the radially outer rib edge, along the entire or only partial peripheral extent thereof, has a radial distance from the geometrical longitudinal center axis of the implant that corresponds to the radial reference distance, and that one or more further rib groups are provided, within which only a number of ribs thereof, i.e., not all ribs, in particular only two ribs situated opposite from one another on the core periphery, or all ribs, have at their radially outer rib edge, along the entire or only partial peripheral extent thereof, a radial distance from the geometrical longitudinal axis that is greater than the radial reference distance.
