Abstract
An abutment for use in connecting a prosthesis to an implant member is provided with an opening in the rear wall thereof within which a pinion gear is mounted in a suitable rotational seal. The pinion gear is provided with a drive socket accessible from the exterior of the abutment such that the pinion gear may be rotated with an appropriate tool. The pinion gear is mated to a bevel gear formed on an annular flange of a retaining screw such that rotation of the pinion gear by the appropriate tool results in proportional rotation of the bevel gear. The retaining screw has a threaded portion and which engages an internally threaded portion of the implant member or of the abutment.
