title: [Fixed orthodontic treatment combined with surgical fenestration in the treatment of impacted mandibular first molars].
abstract: OBJECTIVE
  To investigate the treatment of impacted mandibular first molars by straight wire appliance technique, and evaluate the effectiveness of treatment.
  
  
  METHODS
  Eight patients with first mandibular impacted molars were treated with MBT straight wire appliance. Surgical fenestration was done after sufficient space created. Statistical comparisons were carried out using t test by SPSS 12.0 software package.
  
  
  RESULTS
  Eight mandibular impacted molars were brought into occlusal plane (3.94±0.49 mm), and the overbite and overjet were normal. Good occlusion was achieved. X-ray film showed that alveolar bone growth around the molars was good.
  
  
  CONCLUSIONS
  Orthodontic treatment combined with surgical fenestration can effectively correct the impacted mandibular first molars. Supported by Natural Science Foundation of Zhejiang Province (Y2080253).
