Treatment Summary

Patient Information

  • Age: 46

Aligner Wear time

  • 1-week

Retention

  • Maxillary: Vivera retainer
  • Mandibular: Vivera retainer

Results achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • NormalĀ  overjet and overbite achieved
  • Overjet improved
  • Significant improvement of overjet
  • Midlines coincident
  • Curve of Spee leveled
  • Arches aligned and coordinated
  • Arch form improved

Comments

  • Sequential distalization combined with Class III elastic has been performed to resolve the anterior cross-bite.
  • After establishing normal overjet, the dental midline was corrected by differential IPR and elastics to compensate for the skeletal asymmetry.
  • Overcorrection of lingual root torque at lower interior teeth was designed to avoid periodontal damage.
