评论

  • The crowding in the upper and lower anterior segments was relieved through the staging of interproximal tooth reduction (IPR) in order to avoid unwanted tooth movements.
  • More IPR was prescribed on the upper left quadrant for correction of the upper dental midline by facilitating shifting of the upper midline towards the left.
  • Proper arch form was achieved through mild transverse expansion of the buccal segments.
  • The open bite was closed and the overbite was improved by a combination of intrusion of the upper posterior segments and extrusion of the upper incisors.
  • Light Class II elastics were worn to facilitate coordination between the upper and lower arches.
