ABSTRACT:
A rubber dam clamp comprising a transverse arch connecting two free ends, the two free ends having opposing retentive bonding pads for improved retention, stability, and comfort of rubber dam applications, when applied to a patient's tooth, due to the combination of increased contact surface and use of adhesives between the clamp and the tooth. Further, the invention relates to the adaptation of conventional rubber dam clamps into they type referred to above so as to create a similar combination of frictional force and use of adhesive in order to maintain the position of the clamp in dental procedures.
