  • Gender: female
  • Invisalign Treatment Option: Invisalign Full

Total Treatment Time

  • 32 months

Number of aligners

  • Maxillary: 38 + 20 + 20 = 78
  • Mandibulary: 47 + 17 + 14 = 78

Aligner Wear time

  • 7 -10 days

Retention

  • Maxillary: Vivera
  • Mandibular: Vivera

Results achieved

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

Comments

  • This is a skeletal Class III asymmetric case with Class III malocclusion, crossbite, crowding, and rotation
  • We created space with expansion on the upper arch
  • Space for the lower arch was gained with both distalization and expansion
  • We found Invisalign very effective for arch expansion
  • During sequential distalization we used Class III elastics as anchorage
  • Through digital ClinCheck design, we were able to determine more precisely how to create and manage space for the implant
