Abstract

Abstract A dental anchor magazine housing a dental anchor therein is disclosed, where the dental anchor is for anchoring a superstructure to a tooth. The dental anchor includes threaded sections and an L-shaped manipulating end section joined together by frangible reduced thickness portions. The dental anchor magazine includes a body member having a conical front end, and a square shaped rear end for rotating the magazine about its longitudinal axis. A centrally located passageway extends longitudinally through the body member to receive the dental anchor therein. A slot extends transversely through the body member into communication with the passageway for longitudinal movement of the manipulating section of the dental anchor therein. A pair of notches are provided in the wall of the slot for receiving the manipulating section of the dental anchor to prevent movement of the dental anchor towards the rear end when the forward end of the dental anchor is being initially threaded into a channel of a tooth, where the forward end of the dental anchor extends outwardly from the front end of the body member when being threaded into the channel. The square shaped rear end of the body member is engageably received in either a manual holder for manual rotation thereof or a handpiece holder for power rotation thereof by a dental handpiece. Both the manual holder and the handpiece holder include a pin member for advancing the manipulating section to a first one of the notches.
