评论

  • This was a secondary correction case. Four first premolars were extracted during her first treatment. Class II molar relationship, deep bite, big overjet, and deep Spee curve existed.
  •  Molar distalization was a good choice for the secondary correction case. The patient's class II molar relationship was corrected by upper molar distalization and class II elastic was used for anchorage control.
  • G5 attachments were successful to level Curve of Spee.
  • Because the patient used an orthodontic accelerator during the whole treatment, she changed aligners weekly.
