Treatment summary

Results Achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • 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
  • Harmonic arches were achieved

Total treatment Time

  • 10 months

Number of aligners

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

Aligner wear time

  • Initial aligner changed at 2 weeks for a month then changed at 10 days interval.

Comments

  • Class II canine and molar relationships were corrected to class I relationship with distalization of upper molars and class II elastics
  • Overjet was significantly reduced by retraction of upper incisors
  • Deep bite was reduced by significant intrusion of upper and lower incisors and a slight extrusion of lower premolars
  • Bolton maxillary excess was decreased by performing IPR in the maxillary arch
  • Lip protrusion was reduced by retraction of upper incisors
  • A new implant crown was placed on 36 ( lower left first molar) after orthodontic treatment
  • The reason why clinical outcome didn't have an exact match with the ClinCheck is that I over-engineered ClinCheck plan, especially over-treated deep overbite in this case. Patient was very satisfied with the treatment outcome
