ABSTRACT:
A ring is shaped to fit over the nose of a dental x-ray machine to direct the x-rays to the desired portions of the patient's mouth. Known film retainers which support x-ray film packets at the desired location behind the gums have handles which extend outside the mouth. The ring has adjustable means to fit onto the handle to adjust the position of the ring relative to the film both angularly and distance-wise. An adapter may be used to connect the ring to the handle of the retainer. Alternatively, the handle may slide through an aperture in a tab fixed to the ring.
