Treatment summary

Results Achieved

  • Class I relationship maintained
  • 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 lineĀ was achieved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Total treatment Time

  • 26 months

Number of aligners

  • Maxillary: 42 + 33 + 10 = 85
  • Mandibular: 42 + 33 + 10 = 85

Aligner wear time

  • 1-week

Comments

  • Distalization, expansion and IPR with the Invisalign Teen treatment option make it possible to successfully treat severely crowded dentition of patients with high mandibular plane angle
  • The arch was expanded at the beginning of the treatment to relieve anterior crowding
  • During the refinement, we used IPR to help improve the Bolton discrepancy

Retention

  • Maxillary: Hawley
  • Mandibular: Hawley
