A dental anchor (10 ) is adapted to be installed in a predrilled bore formed in jaw bone tissue for retaining a dental prosthesis, the anchor comprising a generally cylindrical body (12) defining a longitudinal axis, the body being open at a front end thereof and including a cylindrical front cavity (14) communicating with the open front end for receiving a cylindrical core. The front cavity is surrounded by a front portion of said body, the front portion being apertured (24) to accommodate the growth of bone tissue therethrough, and the body being open at a non-apertured rear portion thereof and including a rear cavity (16). The rear cavity is internally threaded to receive externally threaded prosthesis-attachment means (80) and the front and rear portions of said body include front and rear non-threaded outer peripheries (52 and 38), respectively, which are of the same diameter and define a maximum outer diameter of said anchor. Other aspects of the invention relate to a method of implanting the anchor, methods of forming an associated dental prosthesis, methods of drilling the bore in the jaw, and a method of selecting an appropriate dental anchor. |
