“…For residents of western Ukraine, the existence of reliable correlations of medium strength between the linear dimensions of molars (parietal-lingual and mesio-distal dimensions) and indicators of the skull. With the indicators of the facial skull, the largest number of reliable and medium correlations with the height of teeth, crowns, root length, parietal-lingual and mesio-distal dimensions of molars [12]. A similar study, however, conducted with the population of southern Ukraine, found correlations between most sizes of molars on the lower jaw and the length and height of the nose [24].…”

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].…”

“…Data from both domestic and foreign researchers indicate a striking variability of the dental-maxillary system depending on many factors: sex [9], ethnicity [1], facial features [15,20], jaw position [14], regional affiliation [12], features of the structure of the cerebral part of the skull [4], etc. Thus, Ukrainian researchers in the analysis of teleradiograms of Ukrainian boys and girls by the Steiner method established the relationship of the ANB angle with linear (distance 1u_NA) and angular (angles Max1_NA and Max1_SN) characteristics of the upper central incisors and the angle of the lower central incisors (Mand1_NB) [9].…”

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.

The widespread use of methods of cephalometric analysis in practical orthodontics requires the adaptation of normative indicators for members of the local ethnic group. It is also important to study the relationships between cranial and odontometric parameters to understand the effects of these components on each other. The aim of the study was to establish the peculiarities of correlations between the characteristics of basal cranial structures determined by Bjork and Jarabak methods with teleradiographic parameters of the upper and lower jaws and the location of teeth in Ukrainian young men and young women with orthognathic occlusion. Teleradiography was performed in the mode of cephalometric examination of 49 young men (aged 17 to 21 years) and 76 young women (aged 16 to 20 years) who had a physiological bite as close as possible to orthognathic. Cephalometric analysis according to modifications of Jarabak J. R. – Roth-Jarabak and Bjork A. – CFT-Bjork methods, performed using OnyxCeph³™ software, 3DPro version, Image Instruments GmbH, Germany (software license № URSQ-1799). All indicators were divided into three groups according to Dmitriev M. O. (2017): the first group included metric characteristics of the skull, which are used as basic indicators in the methods of cephalometric analysis; to the second group – dental-maxillary in which the skeleton has already been formed and which surgical methods can change the length, width, angles and positions of the upper and lower jaws; to the third group – indicators that actually characterize the position of each individual tooth relative to each other, cranial structures and the profile of the soft tissues of the face. Correlation assessment was performed in the license package "Statistica 6.0" using the non-parametric Spearman method. As a result of the conducted researches in Ukrainian young men and young women with orthognathic occlusion the peculiarities of multiple correlations of characteristics of basal cranial structures determined by CFT-Bjork and Roth-Jarabak methods with teleradiographic parameters of upper and lower jaws and tooth location were established. Both the CFT-Bjork method and the Roth-Jarabak method have more reliable correlations in both young men and young women between the first and second groups (23.3 % for young men and 50.0 % for young women for CFT-Bjork and 48.4 % for young men and 41.1% for young women according to Roth-Jarabak) than between the indicators of the first and third groups (respectively 12.8 % for young men and 7.7 % for young women for CFT-Bjork and 22.5 % for young men and 12.5 % for young women for Roth-Jarabak). The expressed manifestations of sexual dimorphism of the received correlations between the indicators defined by CFT-Bjork and Roth-Jarabak methods both on quantity and force, and in some cases on a direction of correlations are established.
