X-Ray Bite Block Positioners

About bite block positioners

An x-ray bite block is the part the patient closes on; it falls under the FDA section for devices that position and hold x-ray film inside the mouth. Covers go over a block that is reused: the guidance names heat-sterilizable or disposable receptor-holding devices for infection control. The same guidance states that dental professionals should not hold the receptor holder during exposure.

Held in place by the bite, with no aiming arm or ring of its own.
