评论

  • Invisalign is good for molar distalization and space closure.
  • The upper molars were distally moved by 2mm.
  • The upper front teeth were retracted by 8mm.
  • Class II elastics were used to enhance maxillary anchorage and help retract upper incisors.
  • The upper arch was expanded by 1mm per side at the posterior area.
  • No black triangle was shown after retraction by doing some IPR.
  • Molar and canine relationships were both adjusted.
