bisecting angle technique

A dental radiographic technique that requires placement of the film as close as possible to the teeth, causing the film to rest against the crown; visualization of a bisector, which bisects the angle formed by the long axis of the teeth and the film; and positioning of the central ray perpendicular to the bisector. The image produced is distorted in a buccolingual direction Synonym: short-cone technique See: Cieszynski's rule

36) Therefore, the radiographer should make an attempt to obtain and view antemortem records before exposing postmortem images to determine which technique was utilized antemortem--the bisecting technique or the paralleling technique, and follow that technique postmortem.
The radiographer exposing postmortem images must be skilled in use of the bisecting technique because image receptor holders may not be available or it may be difficult to place image receptors parallel to the long axis of the teeth.
