[The x-ray anatomy of the maxilla on orthopantomograms].

The article presents the results of experimental study of the degrees of projective enlargement and deformation of images of different maxillary regions, and the mechanism of maxillary image formation on the orthopantomograms are discussed. The detailed schematic design of the upper jaw and surrounding anatomical formations is presented as seen on orthopantomograms. This is essential for a reliable assessment of possible distortions.
