Treatment in the Spotlight

Dr. K. Malekian

We would like to thank Dr. Malekian for this Class III case submission, that provides an almost step by step insight into the excellent treatment planning with a great treatment end result.

Treatment Summary

Patient Information

  • Age: 31
  • Gender: female
  • Invisalign Treatment Option: Invisalign Full

Total Treatment Time

  • 20 months

Number of aligners

  • Maxillary: 62 + 17 = 79
  • Mandibulary: 62 + 17 = 79

Aligner Wear time

  • Progressive Aligner Change: 14 Days- 10 Days- 7 Days.

Retention

  • Maxillary: Vivera retainer
  • Mandibular: Vivera retainer

Results achieved

  • Class I relationship achieved
  • Class I relationship maintained
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • Posterior crossbite corrected
  • Normal overjet and overbite achieved
  • Deepbite improved
  • Overjet improved
  • Significant improvement ofoverbite
  • 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 linewas achieved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • Maxilla arch expansion
  • Mesialization of upper arch: molars, premolars, canine
  • Sequential lower arch distalization: molars, premolars, canine & incisors ( total distalization 3.25mm )
  • Full-time class iii elastics wear
  • Full-time aligner wear
  • Sequential attachments at lower molars: at the stage, the lower molars finish distalization a 4mm beveled attachment is placed at the buccal surface of the lower molars to increase anchorage
  • Lingual beveled attachments placed at the lingual surface of lower incisors
  • Retraction and simultaneous lingual root torque of lower incisors during lower arch sequential distalization
  • The lower reversed curve of Spee flattened
  • Multiple rotations were aligned with optimized rotation attachments: ur5, ur4, ul4
  • Spacing and diastema were closed at upper incisors
