Standardization of the study of maxillofacial roentgenology. II. Standardization of the methodology of orthopantomography

The main factor of a good quality of orthopantomograms is a correct position of the occlusion plane and chin support, the straightening of the cervical vertebrae, head fixation and a choice of physicochemical conditions for exposure. All these conditions ensure the standardization of orthopantomography, reducing to the minimum errors in investigations.
