ABSTRACT:
A tool for the installation of an abutment or screw in implant dentistry has a knob manually rotatable externally of a patient's mouth on one end of an arm and a bit, releasably secured on a sprocket, rotatable inside the patient's mouth in response to rotation of the knob. A chain connects the bit sprocket to a sprocket attached to the knob, so that the bit rotates about an axis parallel to, but laterally offset by the arm from, the axis of rotation of the knob. A resilient elastomer sleeve is releasably stretched over the abutment or screw and over the bit for initial positioning. Mutliple, interchangeable bits are provided to match different sized abutment or screw heads. The bit shank is recessed intermediate cylindrical portions, for receiving a set screw.
