The LOCKnFOLD rubber dam frame has two hinges and two sliding rings. When the sliding rings are moved to the center, the two hinges are unlocked and can be folded. When they are moved over the hinges, each hinge can be locked separately.
To place the rubber dam on the frame, the two sliding rings are placed in the locked position and the rubber dam is placed on the frame. To take radiographs during treatment, the two sliding rings can be moved to the unlocked position and the whole unit can be folded. As a result , the rubber dam is out of the way, and the practitioner can place the sensor next to the tooth. After taking radiographs, the frame can be unfolded back to its original position. When the rubber dam is on the frame, the two sliding rings do not have to be in the locked position, the rubber dam itself holds the frame open.
Each hinge can be locked separately. So, one sliding ring can be moved over its hinge to lock it, while the other hinge remains unlocked. This allows the practitioner to work on the locked side and keep the other side folded for suction placement or to help the patient breathe easier. This feature allows the practitioner to maintain tooth isolation and keep the patient comfortable throughout a procedure.
