Treatment summary

Results Achieved

  • Class I relationship maintained
  • 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 line¬†was achieved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Total treatment Time

  • 16 months

Number of aligners

  • Maxillary: 60
  • Mandibular: 60

Aligner wear time

  • 7-10 days

Comments

  • Moderate crowding of upper and lower dentition with upper right lateral incisor crossbite was treated using clear aligners, associated with implant anchorage
  • In this case, the crowding was resolved through molar distalization, thus alignment of upper and lower dentition was completed successfully
  • By combining implant anchorage, we have accelerated tooth movements, moving both the first premolar and the second premolar together, as well as canines and incisors

Retention

  • Maxillary:
  • Mandibular:
