ABSTRACT:
A jaw implant comprising a cylindrical, hollow body, threaded on its inner and outer side, and a threaded member in the body acting on horizontally slidable retention pins. The retention pins, subcortically driven into the spongiosa of the jaw bone, are chamferred in such a manner that the longer sides thereof are directed toward the implant support. The edges on the longer sides, at the internal end of the pins, are chamferred for cooperating with the tapered end of the threaded member.
The implant can be reliably secured even in thin jaw bones, in particular of aged patients.
