Results achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • Posterior crossbite corrected
  • Normal  overjet and overbite achieved
  • Deepbite improved
  • 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

  • Sequential distalisation of lower dentition was adopted and Class III elastics were used to improve the anterior/posterior relationship and finished full class I molar and canine relationship
  • Minor proclination of upper anteriors to aid the correction of anterior crossbite
  • Precision bite ramps at additional aligner stage were used in order to improve deepbite correction
  • Did lower incisor proclination and intrusion while doing lower molar distalisation and avoiding retroclination of lower annteriors during class III correction
