Treatment summary

Results Achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • Normal  overjet and overbite achieved
  • Deepbite improved
  • Significant improvement of overbite
  • 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

  • 24 months

Number of aligners

  • Maxillary: 55 + 15 + 13 = 83
  • Mandibular: 55 + 15 + 13 = 83

Aligner wear time

  • 1-week

Comments

  • The patient's compliance was great in this treatment
  • The Invisalign system makes unilateral extraction treatment become easier because of the great anchorage control provided
  • Elastic control made posterior bite became stabler and more predictable

Retention

  • Maxillary: Other clear
  • Mandibular: Fixed/Bonded
