评论

  • Arch asymmetry with anterior interference is the cause of posterior open bite in this particular case.
  • Lower anterior intrusion and arch expansion were performed to remove interference and coordinate the arches.

  • By only Invisalign system without TADS and braces, achieved a good result and enhance patient's experience during the treatment.
