“…Analysis of a sample of 103 normal-occlusal Koreans who underwent a cephalometric study showed that posterior-calibrated data correlated strongly with the vertical position of the maxillary first molar. The conducted multiple linear regression analysis generated models with the highest R 2 value of 0.880 [13].…”

Annotation. The construction of a correct orthodontic intervention that will satisfy the aesthetic and functional needs of the patient requires the perception of the craniofacial region as a single complex. At the same time, it is necessary to understand the relationship of each component of this complex and its influence on each other in order to better predict the expected result of treatment and its planning. The purpose of this study is to review modern scientific sources devoted to the study of the relationship between odontometric and cephalometric indicators. For this, a search for literary sources related to the research topic in the period 2012-2022 was performed on the basis of Google Scholar using keywords and inclusion/exclusion criteria, in particular, the presence of previous review of articles, the representativeness of the sample, and the presence of statistical analysis of the obtained data. The analysis of selected literary sources showed that the vast majority of publications are devoted to the topic of studying the relationship of odontometric and cephalometric indicators under the conditions of pathology of the dental and jaw system. Also, in most sources, researchers do not prefer the use of one or two methods of cephalometric analysis of lateral teleroentgenograms, but use complex analysis methods. At the same time, scientists pay attention to its ethnicity, gender and age when drawing up a sample. Thus, taking into account the relevance of this research topic and at the same time the lack of studies aimed at determining the relationship of cephalometric and odontometric indicators under the conditions of orthognathic bite, there is a need to conduct this kind of clinical experimental study on the Ukrainian population using several of the most common methods of cephalometric analysis.

Annotation. The ability to predict the values of certain teleradiographic indicators and their correlations for young people in need of dental care is a promising area of research. The data obtained will be able to more accurately help doctors build a treatment plan. The aim of the study was to build and analyze regression models of teleradiographic parameters according to the Bjork method in young men and young women with orthognathic occlusion. Cephalometric analysis of lateral teleradiograms (49 young men and 76 young women with orthognathic occlusion) according to the modification of the Bjork A. – CFT-Bjork method, performed using OnyxCeph³™ software, 3DPro version, from Image Instruments GmbH, Germany. Cephalometric parameters were divided into three groups: the first – metric characteristics of the skull, which are used as baseline indicators; the second – indicators of the upper and lower jaws; third – indicators that characterize the position of the teeth relative to each other, cranial structures and the profile of the soft tissues of the face. Regression models of teleradiographic indicators by the Bjork method are built in the license package “Statistica 6.0”. When modeling teleradiography indicators according to the Bjork method, which were included in the second group, depending on the indicators of the first group in young men with orthognathic occlusion, 9 out of 13 possible reliable regression models with a coefficient of determination greater than 0.5 (R2 = from 0.528 to 0.775) were constructed. The constructed regression equations most often include the value of the angles S-N-Pog, NSL/NL, NSL/ML, NL/ML, A-N-Pog, S-N-B and the distance Ii-Is. In young women with orthognathic occlusion, 7 reliable models of indicators of the third group were constructed depending on the indicators of the first and second groups (R2 = from 0.508 to 0.844). The constructed regression equations most often include the value of the angles NSL/ML, NL/ML, A-N-Pog, ML/RL and A-N-B. In young men and young women, the models of indicators belonging to the second group, depending on the indicators of the first group, had coefficients of determination less than 0.5, or were not built at all.
