[Cephalometric study of the effect of orthodontic treatment on the mandible in Class II, Division 1 patients].
In this study, an analysis of the skeletal and dental components of Class II, division I, malocclusion patients, of both sexes, with and or without orthodontic treatment, was established. Based on 4 angular (SNA, SNB, ANB and FMA) and 2 linear (Nperp-Pog and ENA-M) cephalometric measurements analysis, we arrived at the following conclusions: 1--No significant difference was found between cases treated with or without extraction; 2--Sexual dimorphism was observed only with the SNB and SNA measurements, in treated cases; 3--Significant difference was established in all measurements, with the exception of the SNB angle, between cases with or without orthodontic treatment.
