Types of Tooth Movement : Lingual/Labial Change

Lingual/labial movement is another correction we make with a large percentage of aligner cases. This movement usually involves tipping or flaring the crowns out to the labial and in some cases adding an element of torque to the roots.

Lingual/labial movements also require IPR on a percentage of cases depending on how the overall arch form is modified. With anterior only alignment we do not have the option of expanding the arch to relieve crowding.
