ABSTRACT:
A facial frame having an arcuate bottom bar which rests on and pivots about the pogonion on the front of the chin with an arcuate portion which surrounds a greater arcuate portion of the patient's face than has been used heretofore. The bottom bar terminating on opposite ends in upright positions which pass on either side of the patient's head and face as the bottom bar pivots about said pogonion. The frame includes fasteners for securing a dental dam, preferably made from a thin rubber sheet. The frame has fasteners which are oriented so that the dam may be attached to them after it has been installed over the patient's teeth. Other fasteners are on the frame and positioned so that dental tape may be used to tie it in place about a patient's head. The geometry is such that the dental dam does not restrict either the working or the visible area of the patient's mouth, and further such that the frame forms a stable support for the dentist or hand tools.
