Aesthetics is one of the key elements that accompanies modern medicine, in particular, dentistry. The need for treatment not only eliminates the symptoms of the disease but also leads to the restoration or improvement of the aesthetic appearance of the person, and especially the face, gave impetus to the development of new areas of science and technology. An important step in the implementation of such treatments is experimental research to identify the norm for certain categories of the population, primarily according to sex and ethnic group. The aim of the study was to establish the characteristics of cephalometric parameters in Ukrainian young men and young women with orthognathic occlusion, which usually do not change during surgical and orthodontic treatment, depending on sex and facial types. On the basis of the clinic "Vinintermed" teleroentgenography was performed using a dental cone-beam tomograph Veraviewepocs 3D Morita (Japan). Cephalometric examination of lateral teleroentgenograms in 46 young men (aged 17 to 21 years) and 72 young women (aged 16 to 20 years) with orthognathic occlusion was done. The type of face was determined according to the morphological index of Garson. The evaluation of parameters that usually do not change during surgical and orthodontic treatment was performed in the licensed package "Statistica 6.0" using non-parametric methods of evaluation of the results. The percentile ranges of cephalometric parameters, which usually do not change during surgical and orthodontic treatment depending on the facial types of Ukrainian young men and young women with orthognathic occlusion has been established. Pronounced manifestations of sexual dimorphism of cephalometric parameters, which usually do not change during surgical and orthodontic treatment (higher values in young men) are established only for most linear dimensions (values of distances NS, Ar-Go, N-Se, N-CC, P-PTV and S-Ar) in representatives of different types of faces. Both between young men and young women with different face types, there are almost no reliable or tendencies of differences in cephalometric parameters, which usually do not change during surgical and orthodontic treatment.

“…For residents of Western Ukraine, the largest number of significant correlations between molar size and cranial parameters were found with vestibular-lingual and mesiodistal tooth sizes, and for the facial skull with the height and length of the tooth root [12]. While for the inhabitants of Southern Ukraine the corresponding correlations were found with cranial indicators for tooth height and length of their roots, and for facial skull -with tooth height, root length, vestibular-lingual and mesio-distal dimensions [23].…”

Annotation. Determining the characteristics of certain indicators within a certain population, the relationship between certain anatomical structures and parameters of the human body is one of the key tasks of clinical anthropology. Identifying the nature, strength and direction of the interdependencies of such indicators is a key element not only for understanding human nature but also for solving clinical, including dental problems today. The aim of the study was to establish in Ukrainian young men and young women with orthognathic occlusion the peculiarities of correlations of teleradiographic parameters of tooth location determined by Bjork, Jarabak and Sassouni methods with parameters of upper and lower jaws and tooth location. Teleradiography in the mode of cephalometric examination was performed for 49 young men and 76 young women with orthognathic occlusion. Cephalometric analysis was performed using OnyxCeph³™ software, 3DPro version, Image Instruments GmbH, Germany (software license URSQ-1799). Correlation assessment was performed in the license package “Statistica 6.0” using the non-parametric Spearman method. In young men and young women, the features of multiple correlations of teleradiographic parameters of the upper and lower jaws with the parameters of the location of the teeth determined by the methods of CFT-Bjork, Roth-Jarabak and Sassouni. As a result of quantitative analysis of significant correlations between teleradiographic parameters of the upper and lower jaws with the parameters of the location of the teeth found: CFT-Bjork in young men 46.9 %, of which 5.4 % straight strong, 18.5 % straight medium and 2.3 % straight weak and 2.3 % reversible strong, 16.2 % reversible medium strength and 2.3 % reverse weak, and young women – 38.5 %, of which, 2.3 % direct strong, 15.4 % direct medium strength and 6.2 % direct weak and 0.8 % reverse strong, 7.7 % reverse medium strength and 6.2 % of reversible weak; according to the Roth-Jarabak method, 36.2 % of young men, 6.6 % of direct strong, 11.8 % of direct medium strength and 2.6 % of direct weak and 2.6 % of reverse strong, 11.8 % of reverse of medium strength and 0.7 % of reverse weak, and young women – 44.7 %, of which, 3.9 % direct strong, 15.1 % direct medium strength and 7.2 % direct weak and 0.7 % reverse strong, 8.6 % reverse medium strength and 9.2 % reverse weak; according to the Sassouni method, 42.8 % of young men have all medium-strength, and 42.8 % of young women have, of which 35.7 % have medium-strength and 7.1 % have weak straight. Manifestations of sexual dimorphism of the received correlations are established only between the indicators defined by CFT-Bjork and Roth-Jarabak methods.

Annotation. Anomalies of the dental-jaw system are one of the most difficult challenges of modern orthodontics, and accordingly require the use of modern and evidence-based therapy. To predict the results of treatment and proper planning of orthodontic interventions, a reliable tool in the hands of an orthodontist is cephalometric analysis by the Ricketts method. An important step in the successful implementation of this method of analysis is to conduct a study taking into account ethnicity, age, sex and the influence of facial type on teleradiographic indicators calculated by this method. The aim of the study is to build and analyze regression models of teleradiographic indicators used in the Ricketts method for Ukrainian young men and young women with orthognathic occlusion with different face types. Ricketts teleradiography was performed for 49 young men and 76 young women with orthognathic occlusion. Cephalometric analysis was performed using OnyxCeph³™ software, 3DPro version, Image Instruments GmbH, Germany (software license URSQ-1799). The division into facial types was performed by determining the morphological index of Garson. All indicators were divided into three groups: the first group included the main cephalometric points and measurements used in modern cephalometric analyzes Schwartz, Ricketts, Steiner, Roth-Jarabak, Burstone and Bjork and are parameters that usually do not change during surgery and orthodontic treatment; to the second group – metric dental-jaw characteristics by the Ricketts method by which surgical methods can change the length, width, angles and position of the jaws; to the third group – indicators according to the Ricketts method which characterize the position of each individual tooth relative to each other, cranial structures and the profile of the soft tissues of the face. Regression models of individual teleradiographic indicators are built using the license package "Statistica 6.0". Only reliable models with a coefficient of determination higher than 0.6 were subject to analysis. Of the 13 possible facial features, 9 models of teleradiographic indicators (R² = from 0.691 to 0.834) were included to the second group, depending on the indicators of the first group, and 9 (R² = from 0.640 to 0.910) of the 15 possible models of indicators were included to the third group depending on the indicators of the first and second groups. In young men with a wide type of face, the constructed models of indicators included to the second group, depending on the indicators of the first group, most often include the distance Ar-Go (20.7 %), angle POr-NBa (13.8 %), distances N-S and S-E and the ratio N-S:S-Ar' (10.3 % each); and to the models of indicators included in the third group depending on the indicators of the first and second groups – the angle N-CF-A (12.8 %), the distance Ar-Go (10.3 %), the distances N-CC and A-NPog and angle ANS- Xi-Pm, POr-ANSPNS and DC-Xi-Pm (7.7 % each). In young women with a very wide type of face out of 13 possible built only 2 models of teleradiographic indicators (R² = 0.691 and 0.834) which were included to the second group depending on the indicators of the first group and 5 (R² = from 0.628 to 0.919) of 15 possible models of indicators which entered the third group depending on the indicators of the first and second groups. In young women with a very wide type of face, the constructed models of indicators included in the third group, depending on the indicators of the first and second groups, most often include the distance Xi-Pm (18.2 %), as well as the distance P-PTV and angles MeGo-NPog and POr-CFXi (9.1 % each). In young women with a wide type of face from 13 possible 5 models of teleradiographic indicators (R² = from 0.606 to 0.854) which were included in the second group depending on indicators of the first group and 7 (R² = from 0.607 to 0.888) from 15 possible models of indicators which were entered to the third group depending on the indicators of the first and second groups. In young women with a wide type of face, the constructed models of indicators included in the second group, depending on the indicators of the first group, most often include the distance Ar-Go (28.6 %) and the angle POr-NBa and the ratio S-ar:ar-Go (14.3 %), and to the models of indicators included in the third group depending on the indicators of the first and second groups – the distances A-NPog and Xi-Pm and the angle NBa-PtG (10.3 % each).
