Abstract

A bone-embedded implant fixture is interfaced with an aluminum oxide abutment post through which a variety of different arrangements and types of prosthesis superstructures may be supported, including those having separate coping portions surface bonded to the abutment post. An access bore in the abutment post accomodates threaded insertion of a screw fastener carrying a deformable washer to hold the dental implant assembled and seal the gum tissue region into which the abutment post is fitted.
