Treatment summary

Results Achieved

  • Class I relationship achieved
  • Normal  overjet and overbite achieved
  • Significant improvement of overbite
  • Significant improvement of overjet
  • Proper axial inclination of incisors
  • Curve of Spee leveled
  • Arch form improved
  • Aesthetic smile line was achieved

Total treatment Time

  • 24 months

Number of aligners

  • Maxillary: 60 + 25 = 85
  • Mandibular: 60 + 25 = 85

Aligner wear time

  • 1-week

Comments

  • This is a severe deepbite case with an excessive overjet
  • Deepbite was solved by intruding the upper and lower incisors
  • Excessive overjet was solved by upper disatlization and lower incisors proclination
  • We used Class II elastics during distalization.

Retention

  • Maxillary: Fixed/Bonded
  • Mandibular: Fixed/Bonded
