ABSTRACT:
The technical field of the invention generally concerns an expandable dental implant for receiving and supporting a dental prosthesis. The expandable dental implant, securable within a bore formed into bone of a patient's jaw, includes an elongated, hollow, tubular barrel having both an attachment end and an insertion end. The barrel has both a threaded interior surface for screwing the implant into the bore, and a threaded exterior surface for receiving a threaded expander screw. The barrel is pierced about its insertion end by a plurality of radial slits spaced circumferentially around the barrel. The interior surface of the barrel at the insertion end is formed with a smaller diameter than the diameter of the interior surface of the barrel at the attachment end. The expander screw and the interior surface of the barrel are shaped so advancement of the expander screw along the barrel toward the insertion end causes an end surface of the expander screw to collide with the interior surface of the barrel, and to expand the insertion end outward into the surrounding bone.
