ABSTRACT:
The present invention comprises a frame to hold a rubber dam for use during dental surgery. The frame is substantially U-shaped in configuration and convex so as to generally follow the contours of the face. A hinge is positioned in the center of the bottom of the U so that the side frames may individually pivot toward each other or may be brought together. Detent means are positioned on the external surface of the bottom of the frame so that when the vertical members of the frame are pivoted to each other they may be secured together in this folded position. Barbed means are provided on the frame to hold the rubber dam when the frame is in use. In use, the rubber dam is secured to the barbed means on the frame and the frame is placed over the patient's face. An opening is made in the rubber dam and the rubber dam is then clamped to or about the tooth which is to be treated. If it is necessary to have access to the interior of the patient's mouth, either side of the frame may be pivoted to the other or the two frames may be brought together substantially perpendicular to the patient's face. The convex shape of the frame coupled with the dam clamp within the mouth of the patient is sufficient to hold the frame in place during operative procedures, including X-rays if necessary.
