ABSTRACT:
A socket for use in preparing a dental prosthesis and in attaching the prosthesis to pillars attached to the patient's jawbone has a thin-walled tubular extension portion that is long enough to extend entirely through an impression material for the first mold used in preparing the prosthesis and/or through the bridge element of the prosthesis. One or more grooves on the socket enhance retention of the first mold and the bridge element.
