评论

  • In this case, upper frog-pattern retraction and lower molar sequential mesialization were applied to increase anchorage.
  • As for incisors' inclination, the over-treatment proclination was applied for both arches.
  • Most important, the patient was very compliant to all the instructions, and the clinical crowns were long enough for the aligners to grabbed the teeth and demonstrated force mechanism.
