ABSTRACT:
A two-piece abutment system is disclosed. The first part includes a tapering inner surface which is part of a bore extending entirely through the first part. The first part includes a socket for mating with a boss or post on a dental implant. The elongated second part includes a threaded stem for engaging a threaded bore with a dental implant and a post which extends above the first part. The second part extends through the bore of the first part and is screwed into the implant. As the second part is screwed into the implant, a tapering external surface on the post of the second part frictionally locks with the tapering inner surface of the first part. The first part has a metallic core which is surrounded by a ceramic outer portion.
