评论

  • The treatment plan for this case is to keep the upper incisors in its initial AP position and get space from maxillary /mandibular arch expansion and distalization
  • Sequential upper and lower arch distalization plan: distalize molars, premolars, then canine & incisors ( total distalization 1.5mm )
  • A 4 mm horizontal CRT on 3.7 was selected to assist molar distalization
  • Doing arch expansion movement while doing sequential distalization
  • Night-time wear of class III elastics after upper sequential distalization was done to assist lower molar distalization
