| Abstract: |
A dam frame and a dam assembly for use during dental procedures. A two-member elliptical radiolucent plastic frame is provided having arcuate openings matching the upper and lower teeth of a patient and an opening adjacent the throat area. A rubber dam sheet is disposed between the two frame members so as to cover the openings. To produce a dam assembly, the frame is bent along its minor axis to place in a patient's mouth. The dam sheet may be cut or punched to isolate one or more teeth with the uncut portions protecting the patient's throat and mouth.
