A crestal implant including an elongate anchoring section, an implant stump and a transition section. The anchoring section has an elongate core from which several ribs extend forming rib groups. One or more surfaces which extend in the circumferential direction at a radial reference distance from the longitudinal central axis are provided on the transition section. One or more rib groups, in which the radially outer rib edge of the ribs has a radial distance from the longitudinal central axis of the implant, at least approximately corresponding to the radial reference distance, and one or more rib groups are provided within which only some ribs thereof, or within which all the ribs thereof, have on the radially outer rib edges along the entire or partial circumferential extension, a radial distance from the longitudinal central axis which is greater than the radial reference distance.
