[Theoretical presuppositions in the precise tomographic study of the temporomandibular joint]

In order to eliminate typical projective distortions of lateral or standard oblique tomography of the temporo-mandibular joint, authors suggest a preliminary evaluation of the long condylar axis inclination by means of axial radiograph. This method allows to personalize, for each side, the slope of X-ray beam to perform an effectual oblique tomography.
