title: [Treatment of Class II malocclusion using Herbst appliance with headgear and rapid palatal expansion and straight wire appliance with implant anchorage].
abstract: OBJECTIVE
  To investigate the effects of early treatment of Class II malocclusion with Herbst appliance with headgear and rapid palatal expansion and straight wire appliance with implant anchorage.
  
  
  METHODS
  Twenty-five Chinese children (14 males, 11 females, aged from 10-12 years with an average age of 10.5 years) were treated with Herbst appliance with headgear and rapid palatal expansion for 6 months. Then they were further treated with straight wire appliance with implant anchorage. Cephalometric data pre- and post-treatment were measured and analysed. Multiple correlation analysis was performed with SPSS13.0 software package.
  
  
  RESULTS
  Compared with pretreatment, as angle SNB (4.2800±1.4000)° and as angle NP-FH (3.5600±1.0440)° increased posttreatment. as angle SNA (0.5600±0.8206)°, as angle ANB (4.7600±1.2000)°, as angle U1-NA (11.9200±1.4411)° and as angle U1-SN (13.1600±1.7720)° decreased posttreatment (P<0.05).
  
  
  CONCLUSIONS
  Maxillary growth is successfully inhibited and mandibular growth is significantly promoted by Herbst appliance with headgear and rapid palatal expansion. The maxillary dentition is significantly retracted by fixed appliance with implant anchorage and the skeletal pattern of patients is significantly improved.
