Treatment summary

Results Achieved

  • Functional canine guidance on both sides
  • Normal¬† overjet and overbite achieved
  • Overjet improved
  • Midlines coincident
  • Proper axial inclination of incisors
  • Arch form improved
  • Aesthetic smile line¬†was achieved
  • All treatment goals were achieved case

Total treatment Time

  • 9 months

Number of aligners

  • Maxillary: 12 + 12 = 24
  • Mandibular: 10 + 12 = 22

Aligner wear time

  • 2-weeks

Comments

  • Correction of crowding and rotations was performed through IPR and with minimal tooth expansion.
  • Correction of the dental protrusion was solved through posterior expansion, and posterior and anterior IPR.
  • Improvement of the canine class I relationship was obtained through the posterior IPR and distalization.
  • The patient used class II elastics only at night.
  • Second and third molars were not moved for better treatment future stability and anchorage control.
  • The reason to request additional aligners was due a restorative change in tooth 1.5 early in the treatment (aligner number 4).

  • Mandibular:
