Bisecting angle technique

A dental radiographic technique that requires (1) placement of the film as close as possible to the teeth, causing the film to rest against the crown; (2) visualization of a bisector, which bisects the angle formed by the long axis of the teeth and the film; and (3) positioning of the central ray perpendicular to the bisector. The image produced is distorted in a buccolingual direction. Also called short-cone technique.
