Features of cephalometric parameters, which usually do not change during surgery and orthodontic interventions, in Ukrainian young men and women with orthognathic occlusion and different types and profiles of the face according to Schwarz A.M.

Abstract

During the existence of the X-ray method of research, numerous author's methods of cephalometric examination and analysis using the method of lateral teleroentgenography (methods by Schwarz, Down's, Steiner, Tweed's, Harvold, Ricketts, McNamara, Jaraback, Burstone, Bjork, etc.) have been developed. Dentists around the world prefer certain methods, each of which has its advantages and disadvantages. But there is still no single unified methodology for such research and doctors and researchers are constantly trying to improve them and gain new information about their effectiveness. The aim of the study was to establish cephalometric teleroentgenographic parameters and determine their features in Ukrainian young men and women with orthognathic occlusion depending on profiles and facial types according to Schwarz A.M. (hereinafter orthognathic occlusion), divided into separate groups of studies on different profiles and different face types according to Schwarz A.M. (3 groups of different profiles and 3 groups of different face types for people of each sex). Cephalometric teleroentgenographic parameters, which usually do not change during surgery and orthodontic interventions, were studied. Statistical mathematical processing of the research results was performed in the licensed package "Statistica 6.0" using non-parametric methods of evaluation of the obtained results. Numerical reliable and tendencies of differences in certain indicators between groups of young men or women with different profiles or face types have been established. The greatest differences, both in young men and women, were recorded between the indicators determined by the methods of cephalometry by Schwarz A.M. and Bjork A., and the least-by the method of Ricketts R.M. The obtained results testify to the expediency of using the division of young men and women into separate groups by profile and type of face to adhere to the personalized principle in the morphological assessment of cephalometric and gnatometric indicators of lateral teleroentgenography.
