ABSTRACT:
There is disclosed an endosseous dental implant apparatus. The implant has an elongated, substantially cylindrical body, a distal hollow internal chamber and an open distal end. The distal end has a series of dentate ridges that forms a rotary cutting surface for trephining the bone. Proximally there is provided a dental handpiece adapter. At least one spiral osteogroove is disposed on the external surface of the body, extending from the distal portion generally toward the proximal portion and communicating with a recessed osteoreservoir. At least one osteovent is situated in the osteogroove, and has a leading bevelled margin to promote the ingress of bone fragments therethrough into the internal chamber. The osteoreservoir may incorporate a spiral ridge that defines a continuous spiral groove.
