Regression models of the dimensions of the dental arch shape in girls with a physiological bite and a very wide facial type depending on the features of telerontgenometric indicators by the Ricketts method and computed tomographic dimensions of the teeth

Abstract

In Ukrainian girls with physiological occlusion and a very wide face type, based on the features of teleradiometricindicators according to the Ricketts method and computed tomography dimensions of the teeth, all 18 possible reliable highly informative models (R2= from 0.626 to 0.913, p<0.001 in all cases) of linear dimensions necessary for constructing the correct shape of the dental arch were constructed. The models most often include teleradiometric indicators according to the Ricketts method (34.71 %), the width of the tooth crown in the mesio-distal and vestibulo-oral directions (24.79 % and 13.22 %, respectively), upper and lower incisors (15.70 % and 12.40 %, respectively).
