Treatment summary

Results Achieved

  • Class I relationship maintained
  • Functional canine guidance on both sides
  • Normal¬† overjet and overbite achieved
  • 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

  • 20 months

Number of aligners

  • Maxillary: 28 + 12 + 15 = 55
  • Mandibular: 35 + 13 + 10 = 58

Aligner wear time

  • 7 days or 10 days

Comments

  • This is a Class I malocclusion case with severe crowding and severe rotation of the 2.1
  • We created space for both arches with the use of IPR and to prevent potential black triangles
  • Expansion to prevent proclination
  • Vertical elastics were used on posteriors to improve interdigitation during final stage

Retention

  • Maxillary:
  • Mandibular:
