TWO-PIECE DENTAL ABUTMENT

摘要

A two-piece abutment system is disclosed. The first part (10) includes a tapering inner surface (22) which is part of a bore extending entirely through the first part (10). The first part (10) includes a socket (12) for mating with a boss or post (134) on a dental implant (130). The elongated second part (30) includes a threaded stem (32) for engaging a threaded bore (136) with a dental implant (130) and a post (34) which extends above the first part (10). The second part (30) extends through the bore of the first part (10) and is screwed into the implant (130). As the second part (30) is screwed into the implant (130), a tapering external surface (38) on the post (34) of the second part (30) frictionally locks with the tapering inner surface (22) of the first part (10).
