Teleradiographic indicators in young men and young women with orthognathic occlusion determined according to the Bjork method

Abstract

he field of dentistry has been experiencing rapid development for decades, due to the emergence of new technologies and developments in the field of diagnosis, treatment and prevention and the large number of pathologies faced by practicing dentists. In particular, it should be noted that the latter factor plays not the least role in the development of odontology. Indeed, data on the prevalence of occlusal pathology are disappointing. Survey data of preschool children in Brazil indicate that 63.2 % of them have at least one pathology of occlusion, among which the most common are overbite, overbite and poste- rior cross-bite (32.9 %, 34.6 % and 18.7 % respectively). The analysis of the incidence among school-age people of malocclusion in the period from 1991 to 2018 was conducted in China. A total of 117,682 schoolchildren collected data. The overall prevalence of occlusal pathology was 47.92 % (95 % CI: 58.6 %-71.9 %). Class I bite pathology was detected in 30.07 % (95 % CI: 25.37 %-35.48 %), class II in 9.91 % (95 % CI: 7.41 %-13.79 %) and class III in 4.76 % (95 % CI: 3.85 %-6.54 %). The most common pathology was a deep bite (16.67 %, 95 % CI: 11.50 %-23.08 %). Given these factors, the role of the quality of dental care is more important than ever. Against this background, the relevance of research aimed at improving existing data on methods of cepha- lometric analysis of teleradiograms, a powerful tool that allows orthodontists to properly plan and evaluate the course of treatment. Domestic researchers are actively conducting research in this area and studied the normative cephalometric indicators in accordance with various author's methods. However, work on adapting the Bjork methodology still remains isolated and fragmentary. The aim of the study was to establish the sex differences of cephalometric parameters according to the Bjork method in Ukrainian young men and young women with orthognathic occlusion with different face types and their differences from the value of these indicators for residents of European origin.
