Regression models of individual linear dimensions necessary for constructing the correct form of dental arch in young women with a wide face, depending on the features of odontometric and cephalometric indicators

Abstract

The purpose of the study: build and analyze the regression models of computed tomographic parameters necessary to determine the correct shape of dental arches, depending on the odontological and cephalometric parameters for girls with normal occlusion close to orthognathic occlusion and a wide type of face. Materials and methods: for 20 girls with normal occlusion close to the orthognathic bite and with a wide face type, in the license package "Statistica 6.0" developed regression models of linear sizes necessary for constructing the cor- rect shape of dental arches, depending on odontometric and cephalometric indicators. Results: thus, in girls with normal occlusion close to orthognathic occlusion, having a wide type of face, all 18 possible reliable regression models (with a coefficient of determination from 0.620 to 0.973) of the reproduction of individual computed tomographic characteristics of the dental arches of upper and lower dental jaws depending on odonto and cephalometric parameters were developed and analyzed. Conclusions: the results obtained indicate the need to take into account the type of face when calculating the parameters of dental arches.
