Commentaires

  • A scissors bite is difficult to treat for all types of orthodontic appliances
  • We tried to successfully treat this case with aligners and used an experimental new way to open the bite while correcting the scissors bite of all 5 posterior teeth
  • We added attachments on the buccal cusps of all lower molars as a bite block to separate upper and lower arches
  • These attachments were never bonded on teeth
  • The result is quite satisfying and the occlusal relationship was great
  • The lower arch was well expanded and the scissors bite was fully corrected
  • All treatment goals were accomplished.
