Features of t teleroentgenographic parameters of the upper and lower jaws in Ukrainian young men and young women with orthognathic occlusion and with different types and profiles of the face according to Schwarz A. M. Biomedical and Biosocial Anthropology

Abstract

Numerous studies have shown that teleroentgenographic indicators differ in people ofdifferent races, ethnicities, different populations, inhabitants of different geographicalareas and often differ from the values of such indicators described by the authors ofclassical methods of cephalometric analysis. The aim of the study was to establishteleroentgenographic parameters that can be most often corrected during orthodonticand surgical interventions and to determine their features in Ukrainian young men andyoung women with orthognathic occlusion depending on profiles and facial typesaccording to Schwarz A. M. The results of studies of lateral teleroentgenogram of thehead of 49 young men aged 17 to 21 years and 76 young women aged 16 to 20 years witha physiological bite as close as possible to orthognathic using dental cone-beamtomography Veraviewepocs 3D Morita (Japan) are presented in this work. Themorphometric teleroentgenographic parameters of the upper and lower jaws and inter-jaw parameters, which can most often change during surgical, orthodontic, cosmeticinterventions in groups of persons with different profiles or types of faces according toSchwarz A. M., were determined. All significant differences between groups of youngmen with different facial profiles and between groups of young women with differentfacial profiles are of the same type: in both young men and young women with the firsttype of face profile - angle B is greater than in representatives with the third profile type,and angle MM is greater than in representatives with the third and second profile types;both in young men and young women with a second face type profile - distance R.asc.larger than the representatives with the first profile type; in both young men and youngwomen with the third face profile type, the angle F is larger than in the representativeswith the first profile type, the angle I is larger than in the representatives with the firstand second profiles type, and the distances L-Mand and R.asc. larger than therepresentatives with the first profile type; the angle T have greater values in young menor young women with the first profile type of the face than with the second and thirdprofiles type and have greater values in the representatives with the second profile typethan with the first type profile of the face. Another picture is observed in the analysis ofindicators in young men and young women with different face types. Thus, in personswith the third type of face the distance Max is greater than in persons with the first typeand with the second type of face; the angle F in young men or young women with the thirdtype of face is greater than in representatives with the second and first types, and inrepresentatives with the second type - greater than in young men or young women withthe first type of face.
