- This study shows that there are morphological ethnic differences in Class II Division 1 subjects.
Abstract
Aim
To investigate the craniofacial pattern of southern Chinese children with Class II Division I malocclusion and to compare with Chinese population norms and Caucasians with Class II Division I malocclusions.
Materials
Lateral cephalograms obtained from 105 Chinese subjects with Class II Division I malocclusion.
Results
There were no significant sex differences and subsequently the data were pooled. Except for the maxillary plane angle and the angle of the lower incisor relative to the mandibular plane, all of the selected dental-skeletal angular measurements showed significant differences between Chinese with Class II Division I and Chinese norms.
Conclusion
Compared with Caucasians, Chinese with Class II Division I malocclusion have more prognathic maxillas, less retrusive mandibles, flatter chins, steeper mandibular plane angles and more proclined maxillary incisors.
