dc.description.abstract Taking into account the importance of determining the teleroentgenographic indicators of the spatial position of central incisors, arises a scientific and clinical interest in conducting such studies. The purpose of the study is to develop mathematical models of individual characteristics of the position of upper central incisors in young men and women of Ukraine with orthognathic bite by studying the cephalometric indices and conducting direct stepwise regression analysis. With the help of Veraviewepocs 3D device, Morita (Japan) 38 young men (aged 17 to 21 years) and 55 young women (aged 16 to 20 years) with occlusion close to orthognathic bite and balanced faces received side teleroentgenograms. Cephalometric analysis was performed using OnyxCeph3™ software. Cephalometric points and measurements were performed according to the recommendations of A. M. Schwarz, J. McNamara, W. B. Downs, R. A. Holdway, P. F. Schmuth, C. C. Steiner and C.H. Tweed. In the licensed statistical package "Statistica 6.0", using the direct stepwise regression analysis, the following teleroentgenographic characteristics of the position of the upper central incisors were performed: distance 1u_APog, distance 1u_Avert, distance 1u_NA, angle Max1_NA, angle Max1_SN and angle Max1_SpP. In young men and women with occlusion close to orthognathic bite and balanced face, reliable regression models of individual teleroentgenographic characteristics of the position of upper central incisors with a determination coefficient of greater than 0.50 have been developed, depending on the peculiarities of the metric characteristics of the craniofacial complex: in young men of 6 possible models, have been constructed 5 with coefficients of determination R2 from 0.672 to 0.928, and for young women - all 6 possible models with determination coefficient R2 from 0.508 to 0.663. In the analysis of models with a determination coefficient higher than 0.50, it was found that in young men most often the regression equations include - the angle AB_NPOG (12.0%); distance COND_GN, inclination angle I, MAX maxillary length, Se_N distance, Nap angle, NBa-PtGn angle, SND angle and Wits indicator (by 8.0%). In young women most often models include - the angle AB_NPOG and the Wits indicator (by 15.4%); angle N_POG (11.5%); the angle Gl'SnPog' and the distance LPALAT (by 7.7%). en
