US 2022/0087786 A1 · OCCLUSAL SCREW, DENTAL IMPLANT SYSTEM AND SET

Abstract

An occlusal screw for a two-part dental implant system with an anchoring part and an abutment includes a screw head and a screw shank. The screw head apically forms a screw stop. The occlusal screw consists of a ceramic material and has an engagement portion with an outer structure that is not rotationally symmetrical about the screw axis, is cylindrical or conical at least in regions and is suitable for interacting with a corresponding inner structure in a distal recess of a screwing tool, in order to couple the occlusal screw onto the screwing tool in a rotationally fixed manner. A design concerning which the engagement portion occlusally includes a cylindrical region and apically thereof a clamping region, which continuously widens in the apical direction, is particularly advantageous. The clamping region can be for example conical.
