Abstract

A multi-part abutment adapted for use with dental implants such as cylindrical-shaped endosseous dental implants having an internal opening or passage with an internal, non-circular shape at the top includes part one that sealingly engages the opening or passage in the top of the implant at the bottom end of part one, and engages another abutment part, part two, at the top end of part one through a multi-sided projection. Part two has at its bottom end a multi-sided cavity that interdigitates with the projection from part one so that part two can be seated in a plurality of positions atop part one. At the top end of part two is a prosthesis-engaging or prosthesis-forming projection which can be at an angle to the longitudinal axis of the implant, or lie on the longitudinal axis of the implant. Internal passages inside the two parts are colinear when their parts are joined to one another in their intended configuration, permitting the use of a single fastener to join the two abutment parts to one another and to the opening or passage in the dental implant.
