Physiological occlusion is a type of occlusion in which all parts of the masticatory apparatus harmoniously interact. The pathology of occlusion is in violation of this balance. There are many factors that directly affect the occlusion - as a general organization (heredity, the influence of the endocrine system, etc.), and local factors (trauma to the oral cavity, harmful habits). In view of this, the prevalence of various nosological forms of dental-maxillary anomalies (hereinafter referred to as AFC) is a relevant field for research in modern dentistry. After analyzing the scientific works of a number of authors [1-5], we conclude that the ASC often has a combined nature (a combination of different forms of pathologies). Many studies conducted among various populations provide a variegated picture of the distribution of this or that anomaly. So, the analysis of the author, conducted by Hardy et al. [6] showed that the distribution of class III anomalies varies from 0 to 26.7%, depending on the population studied. Therefore, knowledge of the epidemiological situation and the correct definition of a particular form of the disease is crucial in the further planning of treatment tactics.
