Treatment summary

Results Achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • Posterior crossbite corrected
  • NormalĀ  overjet and overbite achieved
  • Midlines coincident
  • Proper axial inclination of incisors
  • Curve of Spee leveled
  • Arches aligned and coordinated
  • Alignment of both arches through derotation
  • Arch form improved
  • Harmonic arches were achieved

Total treatment Time

  • 8 months

Number of aligners

  • Maxillary: 14 + 14 = 28
  • Mandibular: 14 + 14 = 28

Aligner wear time

  • Initial set of aligners changed at 2 weeks interval for 1 month, then changed at 7 days interval after corticotomy was done until the end of treatment

Comments

  • Anterior cross bites was corrected by retroclination of lower incisors and proclination of upper lateral incisors
  • Crowding was resolved with expansion and IPR
  • Class III relationship was corrected with Class III elastics to a Class I relationship
  • Over bite was improved by extrusion of incisors
  • Bolton Excess in lower arch was improved by performing IPR.
  • Corticotomy was performed using piezotome between premolars to premolars in both arches.
  • Aligners changed at weekly interval after corticotomy was done
