Treatment summary

Results Achieved

  • Class I relationship achieved
  • Anterior crossbite corrected
  • Normal  overjet and overbite achieved
  • Deepbite improved
  • Significant improvement of overbite
  • Midlines coincident
  • Curve of Spee leveled
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Total treatment Time

  • 22 months

Number of aligners

  • Maxillary: 38 + 45 + 30 = 113
  • Mandibular: 38 + 45 + 30 = 113

Aligner wear time

  • 1-week

Comments

  • We used the functional occlusion relationship to design the treatment plan
  • We created space on both sides of 2.2 and restored it as 2.1.
  • The crossbite was fully corrected with retraction and intrusion of the lower anterior teeth
  • The leveling of the curve of Spee was the key to achieve the final occlusion
  • Lower incisor extraction was used as an effective way to create a functional crossbite and coordinate upper and lower midline

Retention

  • Maxillary: Invisalign aligner
  • Mandibular: Invisalign aligner
