Abstract A device which aligns X-ray beam to the film at a predetermined vertical angle and a predetermined horizontal angle simultaneously. The specific angles are created by setting the angle indicating arrows to the appropriate angle on the vertical and horizontal scales. This non-parallel plane alignment of beam to film creates the desired image distortion predicted by the buccal object rule and often necessary in the practice of endodontics. The bite block and film holding arm portions are arranged in an off-set manner to allow for radiographing of teeth with endodontic files protruding from them. In addition, the bite block, by means of attached trays filled with dental impression material, e.g. compound, can register a biting position of the jaws. In any successive film exposure, the radiographic view of the original exposure can be duplicated by keying the teeth to the impressed material and re-setting the original horizontal and vertical angles.
A bite block-film holder complex in which the bite block is laterally affixed as viewed from the x-ray source to the film holder portion to allow instruments, e.g. endodontic files, to protrude from the object tooth in an unobstructed manner.
