ABSTRACT:
A safety face bow having inner and outer wires, the outer wires adapted for coupling to a head cap and/or a neck pad and the inner wires adapted for terminating in an orthodontic buccal tube in which a blunt extension beyond the end of the inner wire is added for the prevention of impalement by the ends of the inner wire if the face bow assembly is pulled out of the patient's mouth. In one embodiment, the outer wire is also removably attached to the inner wire with the additional blunt edge forming a latch for retention of the inner wire should the outer wire be pulled while being worn within the patient's mouth.
