评论

  • Determine space selection was the key factor to resolve the severe crowding in the upper and lower arch
  • Staging was also a key factor: We started with high expansion of upper molars and premolars and when gained enough space we continued with arch development and retraction to extrude upper canines
  • IPR was planned at upper and lower premolars
  • Carefull IPR tracking with distalization movement of upper and lower premolars allowed space in order to align high angle rotation of canines 2.3,3.3 and 4.3 .
  • Conventional bite ramps at the buccal surface of lower four incisors were used in order to correct the deepbite
  • Class III elastics were used in order to improve the anterior/posterior relationship and turn Class III canine and molar into full class I molar and canine.
  • Proclination of upper laterals 1.2 and 2.2 in order to correct the anterior crossbite.
  • Arch coordination tool at clincheck Pro was very helpfull.
  • The maxilla and mandible arch form at stage U0-L0 were very asymmetric and required arch form coordination.
  • Lower incisor proclination and simultaneously lower canines were retracted and distalized
