Commentaires

  • After 27 aligners in both arches, the patient was Class I canine on the right side and 3 mm Class II
    canine on the left.
  • Aligner wear compliance was good and oral hygiene was
    excellent.
  • The majority of the crowding in both arches was resolved during
    the mandibular advancement phase.
  • The bilateral posterior open bite present
    would be closed by additional leveling of the curve of Spee, along with lingual
    root torque of the upper anterior teeth.
  • By reducing the anterior interference's,
    the mandible would be able to auto rotate into a better Class I relationship.
  • Additional Aligners Phase: One set of Additional Aligners was used, which
    lasted 9 months (19 U/L stages, weekly aligner changes.)
  • Reverse curve of Spee was added to the set-up of the lower arch to correct the deep bite
    and remove any heavy anterior occlusion, in order to close the posterior
    open bite.
  • A 4 oz. Class II elastic was worn on the left side only for just
    6 weeks, from aligner stages 14 to 19 (with Precision Cuts on the upper canine
    and the lower first molar), to complete the sagittal correction to Class I.
  • All remaining rotations were fully resolved during Additional Aligners. The
    total treatment time for this patient was 21 months (11 months for the
    mandibular-advancement phase, 1 month for transitional aligners awaiting
    Additional Aligners, and 9 months for Additional Aligners with standard
    Invisalign treatment), which is well within the expected treatment time for
    this severity of Class II malocclusion.
