Comments

  • With the arch form improved, the length of the mandibular dental arch was reduced. Paid attention to the root torque when the front teeth were retracted.
  • When the maxillary arch was slightly extended, the teeth were aligned. At the same time the elastic class Ⅲ, produced a small amount of bite jump to anterior crossbite corrected.
  • The original plan is to CC but in wait for the new Invisalign. The patient's feelings reached the expected effect.
