The LOCKnFOLD rubber dam dental 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. And when they are moved over the hinges, the hinges can be locked. 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 without removing the rubber dam or the frame. After taking radiographs, the frame can be unfolded back to its original position.

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.
