  • Invisalign is good at molar distalization.
  • The upper left molars are distally moved by 3.2mm and the lower left molars are distally moved by 2.5mm in this case.
  • A miniscrew was used on the left side of the maxillary posterior to strengthen anchorage, and it can enhance expression rate of molar distalization.
