ABSTRACT:
A holder for radiographic film fits between the jaws; the patient secures the holder steady by biting down thereon. The holder is U-shaped to provide space for root canal files which otherwise prevent the patient from biting down on conventional film holders. The holder accommodates placement of the film in horizontal or vertical direction and also for such placement while filming either jaw. Separate U-shaped holders may be used for anterior and posterior positions and separate posterior holders for the left and right jaws. By inverting the right lower posterior holder, it may be used on the upper left.
