ABSTRACT:
A surgical clamping and drill-guiding instrument for aiding in the placement of transosteal implants is provided. The instrument includes an L-shaped lower member having a horizontal screw receiving portion for receiving a screw with a rotatable wing portion thereon, and a keyed upright. An upper locking member is positioned on the keyed upright for placing the instrument on the gingival crest by pinching a spring along the keyed upright. The instrument is secured in position by tightening the screw which drives the wings into the lower surface of the mandible for providing a vise-like grip. The screw is provided with a central opening for receiving drill guide inserts of varying sizes for drilling through the mandible. The instrument may be placed in as many positions as transosteal implants are necessary.
