  • Harmonic arches were achieved

Total treatment Time

  • 8 months

Number of aligners

  • Maxillary: 35
  • Mandibular: 35

Aligner wear time

  • 1-week

Comments

  • Class I molar relationship on both sides achieved through lower posterior teeth distalization with the help of Class III elastics
  • Anterior crossbite was corrected through the retraction of lower anterior teeth with the help of Class III elastics
  • Anterior deepbite and Curve of Spee leveled through intrusion of lower anterior teeth
  • Upper dental midline moved to the left to coincide with the lower midline
  • Power ridge feature was used on lower anterior teeth for root control during retraction
  • Power ridge feature combined with Class III elastics moved the roots of lower anterior teeth more lingual than the original position before treatment, which significantly improved the periodontal status in the mandibular anterior region

Retention

  • Maxillary:
  • Mandibular:
