Biomechanical Assessment of Root Torque in Clear Aligners: Impact of Trimline Design, Engagers, and Pressure Points With Palatal Compensation Movement

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Background Root torque control is essential for guiding the proper movement of anterior teeth, primarily to prevent periodontal complications. This movement, in clear aligner therapy (CAT), requires precise force application to minimize unintended displacements.
