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.

Comparative Evaluation of Treatment Effectiveness in Skeletal Class III Malocclusion: Surgery‐First Approach Using Clear Aligners Versus Fixed Appliances

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study aimed to assess treatment outcomes, identify predictors of relapse in skeletal Class III patients treated with the surgery‐first approach (SFA), comparing fixed appliances (FA) with invisalign clear aligners (CA). Materials and Methods Forty adult patients treated with bimaxillary surgery and SFA were retrospectively ...
