コメント

  • The camouflage orthodontic treatment of this severe skeletal class II patient contains two elements: 1) upper premolar extraction; 2) arch expansion.
  •  By extracting maxillary first premolars, full class II molarship and normal canineship were achieved.
  • Invisalign offered an effective arch expansion effect: Arch coordination was very important for the cc plan.
  • Attachments on the lingual surface were used to help arch expansion.
