评论

  • By 4 premolar extractions, severe crowding had to be solved.
  • Deep bite and Curve were relieved by the intrusion of lower incisors and extrusion of premolars.
  • To overcome posterior open bite, we used up-down elastics.
  • Class II elastics were used for molar key correction
  • Conventional horizontal attachment was used for extraction space closure without tipping.
