  • Normal  overjet and overbite achieved
  • Overjet improved
  • 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 
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • Upper and lower wisdom molars were extracted pre-Invisalign treatment.
  • The lower wisdom molar extraction was required in this treatment due to lower arch sequential distalization and planned at clincheck treatment plan.
  • The hyperexpansion of upper right first premolar was corrected planning lingual movement with simultaneous torque control.
  • We planned sequential lower arch distalization to correct the class III molar and canine into class I molar and canine.
  • Lower arch sequential distalization provided space in order to retract lower anterior teeth and therefore correct crossbite of upper lateral teeth.
  • The anterior overjet created, allowed us to retract upper incisors and therefore correct dental biprotusion.
  • Patient collaboration during total treatment time was excellent, wearing full-time ( 22 hours/day ) aligners and class III elastics.
