| 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.

I claim:
1. A human facial frame for holding a dental dam, said frame having a generally U-shaped frame means comprising two upright members and an arcuate bottom member adapted to extend around and in front of a mandible, the arc of said bottom member having a radium which is less than 3 inches for surrounding a substantial arcuate portion of a patient's face and extending from molar to molar, said two upright members of the U-shaped frame means being adapted to be positioned on opposite sides of the face and head and in a position generally parallel to a facial plane which is defined by the nasion and the pogonion, said two upright members being adapted to be located in the range of approximately one-quarter of the distance extending from the ear to the facial plane, with the origin of the two upright frame members so located being adapted to rest over approximately the gonion on opposite sides of the patient's head when the bottom of the U-shaped means is positioned in and pivoted around the pogonion in the front of the chin, the frame including a plurality of outwardly projecting fastener means for securing a dental dam around the periphery of the U-shaped frame means, and other fasteners on the frame adapted to anchor dental tape tied in place about a patient's head.
