Abstract: 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.

Abstract: The invention relates to an implant (1), particularly a jaw implant, which comprises several structural zones (5, 6, 12) made of a material which is non-resorbable, particularly from bones, for the implantation on bones or at least in the vicinity of bones. In an advantageous further embodiment of the implant, two or more of said structural zones (5, 6, 12) have respectively different material properties, in particular different physical properties such as different deformation and/or strength properties. The invention also relates to a method for determining load-dependent deformations in different bone regions, according to which X-ray images of the bone regions are taken with and without mechanical load for comparison. By comparing the X-ray images taken of the individual bone regions under or without load, the resulting deformation can be determined due to the applied load.
