A study of the etiology of unilateral Class II, division 1 malocclusion

The purpose of this study was to verify the class I molar relationship in skeletal class II and class II molar relationship in skeletal class I malocclusion with unilateral class II, division 1 malocclusion. The sample consisted of lateral cephalometric radiographs and upper and lower dental casts of 30 unilateral class II, division 1 malocclusion. The results of this study were as follows: 1. Skeletal class I malocclusion was 43%, and skeletal class II malocclusion was 57% in 30 cases of unilateral class II, division 1 malocclusion. 2. In the skeletal class II with unilateral class II, division 1 malocclusion, mandibular first molar on the class I side showed more mesial migration than the opposite side. 3. In the skeletal class I with unilateral class II, division 1 malocclusion, maxillary first molar on the class II side showed more mesial migration than the opposite side. 4. Midline deviation of upper or lower dental arch was 90% in 30 cases of unilateral class II, division 1 malocclusion.
