Abstract Background Orthopantomography panoramic radiography has been used for the study of measurements involving particularly the prediction of the eruption of impacted lower third molars and analyses of measurements of the ramus and head of mandible. The discrepancies involved with the projection of this radiographic image has stimulated the search for further ways to use it particularly in orthodontic treatments and oral and maxillofacial surgeries. The author proposes a graphimetric method for the mandible based on panoramic radiography. The results are expressed in linear and angular measurements aiming at bilateral comparisons as well as the determination of the proportion of skeletal and dental structures individually and among themselves as a whole. The method has been named Panorametry and allows measurement of the mandible Mandibular Panorametry or the posterior mandibular teeth Dental Panorametry . When combining mandible and maxilla it should be referred to as Total Panorametry. It may also be used in the future with Cone Beam computed tomography CT images and in this case it may be mentioned as CT Panorametry. .
