Abstract

Providing maximum individual orthodontic care to the patient is impossible without the use of modern instrumental methods of research and considering odontometric and cephalometric characteristics of representatives of relevant populations of different sex and age. The purpose of the study is to develop and analyze regression models of computed tomography sizes necessary to construct the correct form of dental arches in young women with a very wide face, depending on the characteristics of odonto- and cephalometric indicators. Primary computed tomographic indices of tooth size and cephalometric parameters of 50 young women with normal occlusion close to orthognathic occlusion were obtained from the data bank of the scientific-research center of National Pirogov Memorial Medical University, Vinnytsya. Face type was determined using the Garson morphological index. The following distribution is established: with a very wide face – 21, with a wide face – 20, with a medium face – 6, with a narrow face – 3, with a very narrow face – 0. Therefore, only young women with a wide and very wide face were selected for further modeling. The development of regression models of linear dimensions necessary for the construction of the correct form of dental arches, depending on the features of odonto- and cephalometric indicators in young women with very wide faces, was carried out in a licensed statistical package “Statistica 6.0”. It is established that young women with a very wide type of face with normal occlusion have built all 18 possible reliable models (with a coefficient of determination from 0.863 to 0.962) of linear computed tomography sizes used to construct the correct form of dental arches of the upper and lower jaws in depending on the features of odontometric and cephalometric indicators. Built models in young women with a very wide face type included more often odontometric (73.0 %) than cephalometric (27.0 %) data. Among the odontometric indicators, the most frequently included models are: width of crowns of teeth in mesio-distal direction (20.7 %); width of the teeth at the level of the anatomical neck in the mesio-distal direction (14.4 %) and width of the crowns of the teeth in the vestibulo-oral direction (10.8 %); and among the cephalometric indicators – the greatest length of the head (3.6 %); average width of face and height of lower lip (2.7 % each). Thus, in young women with a very wide type of face with normal occlusion close to orthognathic occlusion, all 18 possible reliable regression models of reproduction of the individual characteristics of the dental arches of the upper and lower jaws depending on the odonto- and cephalometric parameters were developed and analyzed.
