  • Harmonic arches were achieved

Total treatment Time

  • 21 months

Number of aligners

  • Maxillary: 36 + 24 + 11 = 71
  • Mandibular: 36 + 24 + 11 = 71

Aligner wear time

  • 1-week

Comments

  • The desired outcome was achieved by a combination of arch expansion in the upper arch and retraction of the lower anterior teeth
  • Interproximal enamel reduction was performed between the posterior teeth in the lower arch for relieve of crowding and for retraction of the anterior teeth
  • Class III elastics were added to enact and coordinate the movements
  • Lingual root torque was added to the lower incisors for control of the root inclination during retraction
