Rotational panoramic radiograph is widely used in screening as well as primary examination of various diseases in the stomatognathic area. In this report, how diagnostic imaging by rotational panoramic radiograph is performed to fit edentulous patients with prosthesis, focusing upon the mandible, which is often difficult to deal with, is presented, The density compensation system for the temporomandibular joint is used to examine the dental arches and temporomandibular joint simultaneously, which makes it possible to dentermine the morphology as well as the position of the condyles. By adding four fractional radiography of the mandibular condyle using a panoramic machine, movement of the condyles on both sides can also be examined to some extent. Furthermore, the recently developed multimodality panoramic radiography can create transverse section images of the mandible, providing useful information for examination and diagnosis of implant patients, for example, to determine the selection, the location, and direction of implants.The following items were discussed:1. The height of the mandible (the degree of bone resorption)2. The form of the condyle3. The position of the condyle4. Cross sections of the mandible
