  • Aesthetic smile line was achieved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Total treatment Time

  • 10 months

Number of aligners

  • Maxillary: 19 + 16 = 35
  • Mandibular: 21 + 10 = 31

Aligner wear time

  • 1-week

Comments

  • This is a Teen case with Class I moderate crowding and increased overbite/overjet
  • I decided to free space through expansion and IPR
  • 3.7,4.7 Were initially impacted and corrected before additional aligners without any sectional braces or elastics.
  • The most important is that we had to prevent any distalization to avoid impact on 3.7,4.7. T

Retention

  • Maxillary:
  • Mandibular:
