评论

  • Due to the use of the Precision Wings feature we successfully treated this case of class II division 1.
  • In phase I we focused on the mandible growth with the use of the Precision Wings feature
  • In 14 months we successfully expanded the upper arch
  • The impacted canines of the upper jaw erupted successfully, the mandible grew forward and we achieved a class I molar relationship
  • In phase II we aligned both arches and achieved a perfect Class I occlusion .
