complex is the major component for physical, mental and social well-being. Therefore, delayed diagnostics and treatment of dentoalveolar pathology may lead not to social maladjustment only, yet also to an increased risk of periodontal diseases, carious lesions, and temporomandibular joint functional issues. Following the outcomes of studies involving head anthropometric measurements, computed tomograms and lateral teleradiography of 68 people with physiological occlusion and various types of the facial skeleton growth, a method has been proposed, which can be employed to evaluate the facial structure balance, based on the match between the anteroposterior dimensions of the maxilla alveolar process and the mandible alveolar part. Only 76.47±5.14% of patients have been identified as having balanced ratios; 14.71±4.29% of the patients were found to have maxillary sagittal dimensions prevailing, with another 8.82±3.44% featuring the prevalence of the mandible anterior-posterior dimensions. Besides, the dominance of the mandible body dimensions in relation to the branch has been found in all types of growth of the head facial area. The obtained data have been compared with the anthropometric and radiological data of 12 patients with cross occlusion. It has been proven that in patients with cross occlusion, a change in the face configuration and the dental system morphological status depends on the anomaly shape as well as on the degree of the mandible transversal shift. K E Y w o r d s — physiological occlusion; transversal anomalies of occlusion; type of head facial area growth; lateral teleradiography; cone-beam computed tomography. I n t R o D U C t I o n The prevalence of dental anomalies and deformities in Russia, which are leading among the maxillofacial issues, varies considerably in the range of 30.9–82.8%. The progressing growth of dentition malformations, leading to social maladjustment, increased risk of developing carious lesions, periodontal diseases, and temporomandibular joint (TMJ) functional disorders, demands the development and implementation of advanced and highly effective methods for dental pathology diagnostics and treatment [1–9]. Diagnostics of the dental system anomalies and deformations is based on the clinical examinations results and on additional (laboratory) data, while the treatment tactics for this group of patients depends on a whole set of factors, the leading ones being the type of pathology, the severity of changes, the stage of occlusion development (the patient’s age) [10–21]. Orthodontic care in childhood (adolescence) implies creating favorable conditions for balanced growth, the development of the child’s dental system and facial skeleton, which is achieved through eliminating bad habits and improving respective functions. In case of older age groups, this set of measures is expanded with orthodontic equipment, which is often combined with surgical interventions. Experts note that it is a combination of conservative and surgical treatments based on comprehensive diagnostics involving radiological and functional methods that allows achieving a morphological, functional, and aesthetic balance in the dentofacial system structure and functioning along with stable remote clinical outcomes [22–38]. Cross occlusion, related to the anomalies of dentition closure in the transverse direction, is one of the most complex issues entailing maxillofacial aesthetic, morphological and functional changes. The occurrence of cross occlusion among all dentofacial anomalies is not the same for different age categories — in children (adolescents) it is up to 1.9%, whereas in people of mature age it goes up to 3%. The following factors lay the ground for cross occlusion: jaw bones impaired growth due to inflammation issues; reduced chewing function or one-sided chewing with Vladimir Shkarin, Sergey Ivanov, Sergey Dmitrienko, Dmitry Domenyuk, Alexander Lepilin, Stanislav Domenyuk 1 Department of Public Health and Postgraduate Education, Volgograd state medical university, Volgograd, Russia 2 Medical Center of the Peoples' Friendship University of Russia,
