“…Bedoya A. et al found significant differences in the bite force, dental arch transversal width, and bizygomatic width scores from representatives of three different tribes living in the Amazon. [4]. In this regard, there is a need to conduct research on individual populations, considering ethnicity.…”

The aim is development and analysis of regression models of linear dimensions necessary for the construction of the correct form of dental arches in young men with a wide face, depending on the features of odontometric and cephalometric indicators. Material and methods: Primary computed tomographic indices of tooth size and cephalometric parameters of 44 young men with normal occlusion were obtained from the data bank of the National Pirogov Memorial Medical University, Vinnytsya. Face type was determined using the Garson morphological index. In licensed statistical package “Statistica 6,0” developed regression models of linear dimensions necessary for the construction of the correct form of dental arches. Results: As a result of researches, it is established that all 18 reliable models of the sizes used for construction of the correct form of dental arches, depending on peculiarities of odontometric and cephalometric indices with a coefficient from 0.645 to 0.944 are constructed. Built models in adolescents with a broad face type more often include odontometric than cephalometric indicators. The most commonly used odontometric indices are: the width of the crowns of the teeth in the mesio-distal and vestibulo-oral directions, as well as the distance from the middle of the cutting edge to the apex of the root of the teeth in the vestibulo-oral direction. Conclusions: In adolescents with a broad type of face with normal occlusion, all 18 possible reliable regression models of reproduction of the individual characteristics of the dental arches of the upper and lower jaws were determined and analyzed.

“…Previously, methods for modeling the teeth parameters were based mainly on simplified models with numerous assumptions, but now it is important to simulate the size of the teeth, which requires deep knowledge of anatomy and, in particular, the consideration of individual dimensional features of the tooth-jaw and craniofacial system [2,4,6,11,12].…”

Restoration of missing teeth should be done as close as possible to the natural anatomical features of the person's tooth-jaw apparatus. That is why the problem of aesthetics in dentistry has ceased to be only orthopedic and has shifted towards a constitutional and ethnic odontology. The purpose of the study is to construct and carry out analyzes obtained by regression analysis, models of computed-tomographic size of molars, depending on the features of cephalometric indices of practically healthy men of the Western and Eastern regions of Ukraine. A computed-tomographic study of molars with the following odontometry and cephalometry of 36 practically healthy men of the Western region of Ukraine – residents of Volyn, Rivne, Lviv, Chernivtsi, Ternopil, Khmelnytskyi, Transcarpathian and Ivano-Frankivsk regions and 35 men of the Eastern region of Ukraine - residents of Kharkiv, Donetsk and Luhansk regions was performed with the help of the Dental Cone-ray Tomography Veraviewepocs-3D (Morita, Japan). Regression models of linear sizes of molars, depending on cephalometric indices, were conducted using the statistical software package Statistica 6.1. As a result of the conducted research, reliable models of computed-tomographic size of the upper and lower jaws molars were constructed in practically healthy men of the Western [7 models of mesio-distal dimensions (R2 = 0.532-0.646), most of which include sagittal arc (12.5%), outer-eye width, nose depth, distance between nasion and inter-cutter point, body length of the lower jaw on the left, largest head circumference and maximum head length (by 7.5%); 6 models of vestibular-tongue dimensions (R2 = 0.527-0.646), which most often include nasal depth (20.0%), body length of the lower jaw to the left (16.0%), physiological face length and morphological face length (by 12.0%); 1 model of crown height (R2 = 0.579)] as well as Eastern [3 models of crown height (R2 = 0.538-0.682), which most often include nose depth (15.0%), face type, physiological face length, morphological face length, smallest width head and sagittal arc (by 10.0%); 2 models of mesio-distal sizes (R2 = 0.572 and 0.556), which most often include inter eye fossa width (15.4%)] regions of Ukraine. Thus, in practically healthy men from the Western and Eastern administrative-territorial regions of Ukraine, based on the specifics of cephalometric indicators and face type, reliable regression models (with determination coefficient R2 greater than 0.5) of computed-tomographic size of molars of the upper and lower jaws (out of 40 possible 14 for the western and 5 for the eastern regions of Ukraine).

“…Respecto a la poblacion Colombiana, Bedoya y cols reportaron la presencia de arcos dentales frecuentemente ovalados en el maxilar y en la mandíbula en una población indígena del Amazonas Colombiano (22) también se reporta la relación significativa entre la etnia indígena y el arco cuadrangular superior, sin embargo, los arcos ovalados fueron los más prevalentes en las tres poblaciones estudiadas (23). De acuerdo al ancho del arco dental, Alvaran y cols (24) evaluaron pacientes mestizos de Medellín Colombia y en la discusión compararon sus resultados con anglosajones reportaron resultados similares.…”
