title: [Study of esthetic characteristic changes of soft tissue profile of patients with Angle Class division 1 malocclusion treated by functional regulator].
abstract: OBJECTIVE
  Five esthetic indexes were used to evaluate the soft tissue profile changes of patients with Angle Class division 1 malocclusion treated by Functional Regulator.
  
  
  METHODS
  21 patients with Angle Class division 1 malocclusion were treated by functional regulator. Pretreatment and posttreatment cephalograms of every patient were traced to analyze the esthetic characteristic of soft tissue profile.
  
  
  RESULTS
  Most of the indexes tended to normal after treatment.
  
  
  CONCLUSIONS
  Soft tissue profile of most patients with Angle Class division 1 malocclusion was improved after functional orthopedics while changes were different individually. Second stage treatment was still required for some patients.
