Influence of Different Preactivation Patterns and Aligner Materials on the Capability of Aligners to Induce Palatal Root Torque of Upper Incisors: An In Vitro Biomechanical Study

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives Previous studies have demonstrated that aligners with labial‐cervical pressure points can induce root movement, but with initial unwanted tipping. This study assessed the impact of palatal‐incisal pressure points on improving root movement and reducing initial offset.

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.
