Abstract
The study was performed on adult skulls systematized by the occlusion type and the degree of lower dentition preservation. It has been established that there are no differences in the structure of the lower jaw head between skulls with transitional forms of normal occlusion and orthognathic occlusion, but for different types of anomalous occlusion there are statistically significant differences in the main morphometric parameters of the condylar process. It has been established that complete teeth loss significantly changes the sagittal diameter of the mandible head. Therefore, the absence of teeth makes the lower jaw head conical-shaped in most cases (in 61.3%). The features of the mandibular head structure in the dentoalveolar conditions studied can cause changes in the temporomandibular joint, and, accordingly, lead to its dysfunctional disorders.
