코멘트

  • Sequential distalisation of lower dentition was adopted and Class III elastics were used to improve the anterior/posterior relationship and finished full class I molar and canine relationship
  • Minor proclination of upper anteriors to aid the correction of anterior crossbite
  • Precision bite ramps at additional aligner stage were used in order to improve deepbite correction
  • Did lower incisor proclination and intrusion while doing lower molar distalisation and avoiding retroclination of lower annteriors during class III correction
