title: [Cephalometric analysis of the patients with bimaxillary protrusion in south China].
abstract: OBJECTIVE
  The purpose of this article is to characterize the teeth, jaws and soft tissues of the patients with bimaxillary protrusion in south China.
  
  
  METHODS
  The results of cephalometric analysis of 60 patients with bimaxillary protrusion were compared with the normal occlusions in Beijing.
  
  
  RESULTS
  Compared with the normals in Beijing, the mandibles of the subjects were positioned more backward and rotated inferior-posteriorily. The incisors inclined extremely to the labial side and the lower lip was thicker. The mental thickness was less than the normal, and the mental contour was not clear. The middle face was eminent.
  
  
  CONCLUSIONS
  The results suggest it is of critical importance to manage to adjust the position of jaws, to control the molar anchorage strictly, and to achieve the maximal incisor retraction, so as to benefit the improvement of facial features.
