For Ukrainian young men and young women with different facial profiles according to Schwarz A. M. with normal occlusion close to orthognathic occlusion and a harmonious face, regression models of teleroentgenographic parameters, which can be corrected during surgery (2 group of indicators) depending on the parameters that usually do not change (1 group of indicators) were constructed and analyzed.
In young men, 10 of 27 possible reliable regression models with a coefficient of determination greater than 0.6 (R2 = from 0,642 to 0,995) were constructed, and in young women – 13 models from 27 possible (R2 = from 0,619 to 0,956). Both for young men and young women, the most models of indicators of the second group are built for linear dimensions – both young men and young women have 7 models from 9 possible each.
The constructed regression equations of teleroentgenographic indicators included into the second group according to the Schwarz A. M. method the most often comprise the following indicators of the first group: in young men – ar-Go distances according to Burstone C. J., N-CC according to Ricketts R. M., N-Se according to Schwarz A. M. and indicator N-S:S-Ar' according to Bjork A.; in young women – indicator S-ar:ar-Go according to Jarabak J. R., distances N-S according to Jarabak J. R. and ar-Go according to Burstone C. J. and angle POr-NBa according to Ricketts R. M.
