Abstract
A reusable comfort enhancing frame for holding an intraoral x-ray film packet is taught which includes four integrally formed side members with a single contiguous perimetric contact surface having a generally rounded cross-sectional configuration and rounded comers. There is a pocket formed in the four integrally formed side members adapted to have the intraoral x-ray film packet inserted and retained therein, and removed therefrom. In one embodiment, there is a slot in one of the four integrally formed side members through which the intraoral x-ray film packet can be inserted to reside in the pocket. In a second embodiment, the pocket is a snap-in pocket comprising at least one lip element projecting from an interior peripheral wall of the four integrally formed side members and at least two snap-fit elements also projecting the interior peripheral wall of the four integrally formed side members.
