ABSTRACT:
A self-locking cylindrical drive (10,10') to deliver and assemble internally hexed prosthetic components such as screws and abutments into place is shown. The head (14) of the tool engages and locks with the flat side surfaces of the internally hexed prosthetic component. The tool (10,10') allows for extra-oral assembly of a component with the tool to minimize any risk of a component falling off or being lost in a patient's mouth during delivery of the component. Final seating of the component is then accomplished using a conventional hexagonal drive tool with appropriate delivery torque. The tool is formed into both a standard hand driven wrench (10) and contra-angle drill (10').
