For the successful treatment of anomalies of the dentition, it is necessary to understand the patterns of development of the body and the growth of facial bones. The starting point for studying the pathogenesis of malocclusion is the orthognathic bite. Previous studies for this purpose are based primarily on the assessment of linear and angular parameters that characterize the relationship of facial structures. However, there are practically no works devoted to the study of the growth features of the facial skeleton in orthognathic occlusion, or they indirectly relate to this issue. The aim of this work was to study the features of the growth of the facial skeleton with orthognathic occlusion using X-ray cephalometric (RCM) analysis. The material for the study was 61 teleroentgenograms in the lateral projection of persons with orthognathic bite from 16 to 27 years old (32 men and 29 women), who assessed the height-depth structure of the facial skeleton according to the method we developed. The results of the study showed a fairly pronounced variability in the structure of its structures. Statistical analysis made it possible to establish that with orthognathic occlusion there is an increase in the height of the facial skeleton during the transition from its neutral type of growth to the predominance of the vertical one and a decrease in the height of the facial skeleton during the transition from the neutral type of growth with a tendency to horizontal.
