Treatment Summary

Patient Information

  • Age: 32
  • Gender: female
  • Invisalign Treatment Option: Invisalign Comprehensive

Total Treatment Time

  • 20 months

Number of aligners

  • Maxillary: 39 + 23 = 62
  • Mandibulary: 39 + 23 = 62

Aligner Wear time

  • Progressive Aligner Change: 14 Days- 10 Days- 7 Days.

Retention

  • Maxillary: Invisalign aligner
  • Mandibular: Invisalign aligner

Results achieved

  • Class I relationship maintained
  • Functional canine guidance on both sides
  • Posterior crossbite corrected
  • Normal  overjet and overbite achieved
  • Midlines coincident
  • Proper axial inclination of incisors
  • Arches aligned and coordinated
  • Alignment of both arches through derotation
  • Arch form improved
  • Aesthetic smile line was achieved 
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • The treatment plan for this case is to keep the upper incisors in its initial AP position and get space from maxillary /mandibular arch expansion and distalization
  • Sequential upper and lower arch distalization plan: distalize molars, premolars, then canine & incisors ( total distalization 1.5mm )
  • A 4 mm horizontal CRT on 3.7 was selected to assist molar distalization
  • Doing arch expansion movement while doing sequential distalization
  • Night-time wear of class III elastics after upper sequential distalization was done to assist lower molar distalization
