Treatment summary

Results Achieved

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

  • 17 months

Number of aligners

  • Maxillary: 35 + 27 = 62
  • Mandibular: 35 + 27 = 62

Aligner wear time

  • 1-week

Comments

  • Patient with a severe deep overbite which caused attrition of the lower incisor
  • To correct buccal crossbite of 1.7 and 2.7, we extracted the 1.8 and 2.8 before the start of orthodontic treatment
  • During orthodontic, we saw late mandibular growth

Retention

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