The described principles are the key features of the paralleling technique, also known as the extension cone paralleling technique (ECPT). The occlusal technique involves placing the film on occlusal surfaces and directing the central ray perpendicular to the film. The bisecting technique involves placing the film as close as possible to the tooth and bisecting the angle between the tooth and the film. The localization technique is used to identify the exact location of an object in the maxillofacial region.
