Comments

  • We used the functional occlusion relationship to design the treatment plan
  • We created space on both sides of 2.2 and restored it as 2.1.
  • The crossbite was fully corrected with retraction and intrusion of the lower anterior teeth
  • The leveling of the curve of Spee was the key to achieve the final occlusion
  • Lower incisor extraction was used as an effective way to create a functional crossbite and coordinate upper and lower midline
