评论

AP:

  • Distalization of lower molar and procline lower anteriors to get space to align lower teeth;
  • distalizaion upper molar to achieve Class Ⅰ and align anteriors;
  • since lower needs distalization, TADs were used to increase anchorage on A/B/C;
  • added LRT to get proper U incisors inclination;
  • IPR on lower to correct Bolton discrepancy and black triangle.

Vertical:

  • Intruding anterior and extruding posteriors to level curve of Spee;
  • extruding 1.2 to improve smile Arc.

Transverse:

  • Slightly expanding U&L arch to improve the width of the smile.
