title: [Treatment of mandibular retrusion patients with Forsus appliance following growth spurts].
abstract: OBJECTIVE
  To evaluate the clinical effects of Forsus appliance in treatment of patients with mandibular retrusion after the growth spurts.
  
  
  METHODS
  15 cases of Class II malocclusion with small lower jaw were treated with Forsus appliance. Cephalogram pre-and post-treatment was taken,the width of dental arch was measured, and questionnaire were collected from the patients. SPSS10.0 software package was used for paired t test.
  
  
  RESULTS
  SNB increased 1.42 degrees, ANB reduced 1.65 degrees, and Forsus appliance brought about 2.12 degrees reduction of the facial soft tissue profile convexity. The width of dental arch was extended. Overbite reduced and overjet went down 4.98 mm.
  
  
  CONCLUSIONS
  Forsus appliance can improve sagittal discrepancy and soft tissue profile convexity of patients with Class II malocclusion.
