Comments

  • Invisalign aligners had advantages on molar distalization.
  • The upper left molars were distalized moved by 3.8mm and the upper right molars were distalized moved by 2.6mm, which opened 6.3mm space to restore 2.3(implant).
  • Used mini screws on the maxillary posterior-tooth area to strengthen anchorage and enhance the expression rate of molar distalization.
