In Vitro Aligners Force Analysis in the Maxillary Arch During En‐Masse Retraction With Different Attachment Positions

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study aimed to analyse the three‐dimensional forces acting on maxillary teeth with aligners activation of en‐masse retraction based on the different attachment positions in vitro. Methods Three groups were designed for the same 0.25 mm en‐masse retraction forces with three different attachment positions.

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.
