Results achieved

  • Class I relationship achieved
  • Functional canine guidance on both sides
  • Normal  overjet and overbite achieved
  • Deepbite improved
  • Significant improvement of overbite
  • Significant improvement of overjet
  • Midlines coincident
  • Proper axial inclination of incisors
  • Curve of Spee leveled
  • Arches aligned and coordinated
  • Aesthetic smile line was achieved 
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • This is Class II division 1 case with severe crowding in lower anterior teeth.
  • Non-extraction protocol treatment was planned due to patient's soft tissue profile and anterior deep bite condition.
  • Sequential distalization was performed to achieve Class I molar and canine relationship. Class II elastic was served as an anchorage reinforcement.
  • No TADs were used in the treatment process. Unlike distalization with the fixed appliance system, at least 2 TADs were necessary for achieving the same treatment result with this case.
