  • 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

  • 14 months

Number of aligners

  • Maxillary: 44 + 15 = 59
  • Mandibular: 26 + 15 = 41

Aligner wear time

  • 1-week

Comments

  • This is a Class II div I severe crowding case with large overjet and deep bite
  • Upper dental midline shift to the right side due to 1.3 impacted canine with space deficiency
  • Sequential distalization in upper arch to correct Class II to Class I
  • Expansion and IPR to gain space to prevent proclination
  • We created space through expansion and IPR in the lower arch
  • We improved the alignment of the teeth and the patient's smile and profile
  • Vivera retainers will be used for retention
