Fastener for movable part of dental prosthesis

摘要

The fastener consists of a female tapered dovetail part forming a groove with an undercut profile (5) and a projecting male profile (1) forming a bolt fitting into this groove. The bolt is tapered, the section being narrower at the top (4) than at the bottom. A bevelled face (8) at the larger bottom end of the bolt may assist in removal of the bolt. There is a cavity which may receive a spring bolt.
