Abstract: A single-piece ceramic dental implant is provided, with a distal enossal threaded region, a gingival intermediate region and a proximal region. A thread is arranged in the threaded region and has a core radius and an outer radius of the thread. A proximally accessible insertion geometry for screwing the threaded region into a bone tissue is arranged in the intermediate region, wherein the insertion geometry is designed as a non-rotationally-symmetrical outer structure. The proximal region includes at least one structure for fastening a single-part or multi-part attachment element. An implant diameter in every section perpendicular to the implant axis, in the intermediate region is equal to or larger than the double of the core radius of the thread. Thus each implant diameter through the insertion geometry is equal to or larger than the double of the core radius of the thread.

Abstract: The ceramic implant system includes an implant with a proximal region having an inner cone, and an abutment with a distal region having an outer cone. The distal region of the abutment and the proximal region of the implant in a clamping region in each case include at least one conical clamping surface which, in pairs, are adapted to one another in an accurately fitting manner such that the abutment and the implant of the ceramic implant system are connectable by way of a clamping connection.

Abstract: A method for manufacturing an inner structure as an insertion geometry and/or as a rotation lock of a ceramic implant or of a ceramic attachment element. Thereby, a rotating disc for removing ceramic material is advanced in an advance direction of the rotating disc perpendicular to the rotation axis of the disc, into a proximally accessible surface of the ceramic implant or into an end surface of a ceramic attachment element.
