MODELING OF DENTAL ARCH DIMENSIONS IN GIRLS WITH PHYSIOLOGICAL OCCLUSION AND A VERY WIDE FACIAL TYPE DEPENDING ON CEPHALOMETRIC INDICATORS ACCORDING TO THE BURSTONE METHOD AND CT TOOTH DIMENSIONS

Abstract:

It was established that all 18 possible reliable highly informative regression models of linear dental arch parameters depending on the characteristics of cephalometric indicators according to the Burstone method and CT dimensions of the teeth of the upper and lower jaws were constructed for Ukrainian girls with physiological occlusion and a very wide facial type (coefficient of determination R2= from 0.742 to 0.931, p<0.001 in all cases). Analysis of the frequency of inclusion of cephalometric indicators according to the Burstone method and CT tooth dimensions in the regression equations for girls with physiological occlusion and a very wide facial type showed that the models most frequently included cephalometric indicators (28.57 %), crown width in the mesiodistal (22.86 %) and vestibulo-oral (14.29 %) planes. Analysis of the frequency of inclusion of the corresponding teeth in the regression equations for girls with physiological occlusion and a very wide facial type showed that the models most frequently included upper incisors (24.00 %), lower incisors (22.00 %), lower premolars (13.00 %), lower canines and upper premolars (both 11.00 %) and upper canines (10.00 %).
