Comparisons of craniofacial features of English children with Angle Class II division 1 and Angle Class I occlusions

This study was based on a cephalometric analysis of 68 English children composed of two groups: one group exhibiting Angle Class II division 1 occlusion and the other with Angle Class I occlusion.

The object of this study was to investigate differences in the dimensions of the craniofacial complex between the Class II division 1 group and the Class I group.

It was found that the only significant differences between the Class II division 1 and Class I groups with regard to craniofacial dimensions were a shorter mandible, a higher maxillary-mandibular plane angle, and a marked proclination of the upper incisor teeth in the former group.
