Avaliação cefalométrica da posição dos incisivos em pacientes portadores de má oclusão classe II 1. divisão

Abstract

Class II malocclusion is characterized by an incorrect relationship of the upper and lower arches, either by skeletal changes, by dental alterations, or by a combination of these factors. The correct diagnosis, planning and treatment should be done individually on each patient in order to achieve more efficient results. The aim of this study was to evaluate cephalometric radiographs of patients with class II malocclusion, division 1. Computerized cephalograms of patients of both genders with ages between 11 and 18 years old were analyzed in a database of a radiological clinic in the city of Manaus - AM. The positions of the upper and lower incisors were evaluated between each other and in relation to their respective bone bases. The results were tabulated and analyzed statistically using analysis of variance (ANOVA) and the student t test and concluded that the female gender was more prevalent among the subjects studied; the frequency and median age of volunteers was between 13 and 20 years; it was also observed that the type of malocclusion more common was class II bilateral; with respect to the angles it was observed that for all magnitudes there was a statistically significant difference (p<0.05) and there was no sexual dimorphism
