ABSTRACT:
A rubber dam (1) used for protecting a patient (2) during dental procedures. The dam (1) includes a symmetrical round frame (3) which supports a flexible membrane (11). A prepunched hole (19) located approximately 0.5 inch from the membrane center (18) permits rotation of the frame (3) in order to position the hole (19) over the desired tooth (13) without causing the relative position of the frame (3) with respect to the patient's face to be substantially altered.
