title: Cephalometric morphology of Chinese with Class II division 1 malocclusion.
abstract: OBJECTIVE
  To investigate the craniofacial pattern of southern Chinese children with Class II Division 1 malocclusion and to compare with Chinese population norms and Caucasians with Class II Division 1 malocclusions.
  
  
  METHODS
  Lateral cephalograms obtained from 105 Chinese subjects with Class II Division 1 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 1 malocclusion and Chinese norms.
  
  
  CONCLUSIONS
  Compared with Caucasians, Chinese with Class II Division 1 malocclusion have more prognathic maxillas, less retrusive mandibles, flatter chins, steeper mandibular plane angles and more proclined maxillary incisors.
