Comments

Inviisalign aligners have advantages on molar distalization.
The upper left molars are distally moved by 3.8mm and the upper right molars are distally moved by 2.6mm, which open 6.3mm space to restore 23（implant）.
I use miniscrews on maxillary posterior-tooth area to strengthen anchorage, and it can enhance expression rate of molar distalization.
