Annotation	Numerous studies prove the opposite viewpoint and conclusions about the influence of cephalometric parameters of hard and soft tissues on the aesthetic result that the physician gets at the end of orthodontic treatment. Therefore, there is a need to continue research on the accumulation, analysis and modeling of the patterns of the structure of the craniofacial complex, taking into account ethnic, age and sexual characteristics. The purpose of the work is to study the features of cephalometric parameters in Ukrainian boys and girls with orthognathic bite using the Holdaway method compared to the results established for other races and ethnic groups. With the Veraviewepocs 3D device, Morita (Japan) in 38 boys (in age from 17 to 21 years) and 55 girls (aged from 16 to 20 years) with physiological bite maximally close to the orthognathic side teleroentgenograms were obtained. Measurements were carried out in accordance with the recommendations of R. A. Holdaway (1983, 1984), and cephalometric points were determined according to A. E. Athanasiou (1997) and S. I. Doroshenko, Ye. A. Kulgynskiy (2007). The article presents the cephalometric parameters of soft facial tissues by the Holdaway method for the Ukrainian population of juvenile age with orthognathic bite and evaluates the discrepancies of these parameters with the results obtained by researchers in the study of other populations according to this technique. Among the Ukrainian boys or girls with orthognathic bite and gender-specific indicators of the Saudi, Turkish, North American, Palestinian and Persia populations, as well as with the Japanese (regardless of sex), there are numerous differences in teleroentgenogram indices by the Holdaway method. The largest number of discrepancies in these indicators is set with the Japanese, and the smallest - with the Palestinians.
