Treatment summary

Results Achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • Posterior crossbite corrected
  • Normal  overjet and overbite achieved
  • Significant improvement of overbite
  • Significant improvement of overjet
  • Midlines coincident
  • Proper axial inclination of incisors
  • 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

  • 29 months

Number of aligners

  • Maxillary: 61 + 62 + 8 = 131
  • Mandibular: 61 + 62 + 8 = 131

Aligner wear time

  • 1-week

Comments

  • Expansion on the upper arch to correct posterior crossbite on the left side
  • Distalizing lower right posterior teeth to achieve Class I molar relationship with TADs used to enhance anchorage
  • Intruding the lower posterior teeth to make mandibular rotate in order to correct the anterior open bite without extruding the anterior incisors

Retention

  • Maxillary: Other clear
  • Mandibular: Other clear
