The aim of this study was to evaluate the dentoalveolar characteristics of the dental arches of patients with Class II, division 2 malocclusion and to compare them to the dentoalveolar characteristics found in Class I occlusion. Dental casts of 32 individuals with Class 11, Division 2 malocclusion (11 boys and 21 girls, mean age 13.8 years) and of 30 individuals with Class I occlusion (17 boys and 13 girls, mean age 13.5 years) were used for this study. A total of 19 variables were examined and Student t-test was used to define possible differences between patient and control groups. To define the error of the method, double measurements of 40 randomly selected dental casts (20 patients and 20 controls) were performed. Analysis of results showed that patients with Class II, division 2 malocclusion presented (a) dental arches that were narrower, smaller (shorter) and more crowded anteriorly, and (b) smaller apical bases in comparison to subjects with Class I occlusion.
