评论

  •  12 and 22 were microdontia, therefore I extracted 42 to coordinate the anterior Bolton index and align the lower arch.
  • Upper molars were distalized by 2mm per side to adjust Class II molar relationship to Class I molar relationship.
  • Invisalign aligners had great advantages on anterior intrusion and deep bite improvement.
