title: [Study of facial soft tissue profile on angle Class II malocclusion with various vertical growth patterns].
abstract: OBJECTIVE
  To investigate the difference of the facial soft tissue profile on Angle Class II malocclusion with various vertical growth pattern.
  
  
  METHODS
  The samples (n = 84) were divided into three groups (low-angle, medial-angle, high-angle group) based on their SN-MP angle. Their cephalograms were measured and all data were analyzed by SPSS12.0 software.
  
  
  RESULTS
  There were some regular changes in most facial profile variables while the mandibular plane angle increased: the facial profile convexity and the upper- and lower-lip convexity increased significantly; the depth of anterior lower face decreased from too large to small; the radian of upper- and lower- lip curve changed from too winding to upright.
  
  
  CONCLUSIONS
  Vertical growth patterns make significant differences to soft tissue facial profile on Angle Class II malocclusion.
