Comments

  • The first series mainly expanded the arch, unlocked the mandible, and assured the real occlusion.
  • In the second series, we combined two Tads over the zygomatic area to distalize the upper and lower arch and the other two Tads for a correct gummy smile and occlusal plane canting.
  • During largely intruding and retracting upper dentition, we added a vertical jump and vertical elastic for the bite set.
  • In the end, used 8 more aligners for esthetic detailing.
