A plastic shank holding a metal dental anchor therein is disclosed, wherein the dental anchor is for anchoring a superstructure to a tooth. The dental anchor includes at least one threaded section and one manipulating end section joined together by a frangible portion so that the sections can be severed. The shank includes an opening for receiving the manipulating end section of the dental anchor in a force-fit connection therebetween, where the manipulating end section includes torque transferring wing portions for permitting the shank to pivot relative to the dental anchor when the dental anchor is being threaded into a channel in a tooth. A plastic hand driver is provided for receiving the shank therein, where the hand driver includes an abutment portion for rotating the shank, and projections for providing a snapped-in connection between the shank and the hand driver to permit a pivotal relationship therebetween while releasably retaining the shank within the hand driver. |
