  • 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

  • 28 months

Number of aligners

  • Maxillary: 68 + 24 = 92
  • Mandibular: 68 + 24 = 92

Aligner wear time

Comments

  • Closure of all extraction spaces (including a 10mm space) was achieved without tipping in this teen case
  • G6 feature was used in 3 of the 4 quadrants
  • Even the deepbite was improved after the closure of extraction space
  • The protrusive profile was improved with good control of incisor torque
  • 4.3 was extruded successfully
  • Upper and lower midlines are coincident

Retention

  • Maxillary: Other clear
  • Mandibular: Other clear
