ABSTRACT:
An implant assembly and method is provided, as well as a system and method for exposing an embedded implant after osseointegration has taken place. The implant assembly comprises an implant member for embedding in the jaw and a rest factor member for securing to the implant member, the rest factor member having an upper rest surface just above the tissue level for opposing an overlying portion of a prosthesis anchored elsewhere in the jaw to form a nonretentive rest or support for accepting down pressure from the prosthesis. The implant member is relatively short and can be installed in distal jaw regions without interference with the mandibular nerve, and has an undersurface having a shape designed for stable integration with the bone while resisting sidesway. The method includes cutting out a bore in the jaw for receiving the implant, inserting the implant and an attached healing screw in the implant, closing the implant site and allowing osseointegration to take place over an extended period, and subsequently uncovering the implant site, removing the healing screw, and securing the rest factor member in the implant.
