Treatment summary

Results Achieved

  • Class I relationship maintained
  • Functional canine guidance on both sides
  • 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

  • 15 months

Number of aligners

  • Maxillary: 43 + 15 = 58
  • Mandibular: 26 + 15 = 41

Aligner wear time

  • 1-week

Comments

  • This is a Class I malocclusion with severe crowding and deep bite case
  • We created space in the upper arch with the use of IPR for Bolton's discrepancy due to lower 3 -incisor condition
  • We created space in the lower arch with expansion and lower anterior teeth proclination

Retention

  • Maxillary: Vivera
  • Mandibular: Vivera
