Dental rubber dam frames are used to hold rubber dams in place while they are being used to isolate the operative tooth or teeth. These frames are often made of plastic or metal and should be designed to be easily and comfortably placed in the patient's mouth while securely holding the dam tightly in place. These frames can be either disposable or reusable, but in either case, having a sterile supply of rubber dam frames on hand can be very important at a restorative dental practice.
