Abstract
A reusable bite block/film packet holder is taught which includes comfort enhancing features for holding intraoral radiographic film packets therein and for proper positioning in a patient's mouth. The bite block/film packet holder includes a bite-block and a support bracket extending at an angle of about 90° from the bite-block. There is a slot in the bite-block immediately adjacent the support bracket for engaging an edge of an intraoral film packet inserted therein. A perimetric border at the peripheral edge of the support bracket has a generally rounded cross-sectional configuration and extends beyond the dimensions of the intraoral film packet inserted in the slot. Thus, the sharp, die-cut edges of the film packet are prevented from uncomfortably engaging the soft/sensitive tissues of a patient's mouth. Rather the rounded, soft-feeling perimetric border of the bite block/film packet holder is the contacting element.
