title: [The clinic skill in fixed appliance based on characteristics of Chinese normal occlusion].
abstract: OBJECTIVE
  To study the bracket placement and arch wire bending based on ethnic differences and individual differences of normal occlusion.
  
  
  METHODS
  The prominence, tip, torque, upper first molar offset of crown and arch form between Chinese and Caucasian normal occlusion were compared.
  
  
  RESULTS
  The results showed the ethnic differences of prominence, tip, torque, upper first molar offset of crown and arch form between Chinese and Caucasian normal occlusion. The placement of bracket was influenced by the crown morphology.
  
  
  CONCLUSIONS
  The adjustments of the bracket placement and arch wire bending with Edgewise and pre-adjusted appliance are necessary to adapt to ethnic difference and individual difference.
