Effect of high trimline aligners on distalizing mandibular molars: a three-dimensional finite element study

The research verified the biomechanical advantages of high trimline aligners in the distal movement of mandibular molars and underscored the critical role of aligner design and traction application in optimizing orthodontic treatment outcomes. Additionally, it raised concerns regarding the potential for root resorption due to significant stress in the periodontal ligament, necessitating thorough observation of patients, particularly those fitted with high trimline aligners. Despite these insights, the study's findings are derived from the data of a single patient, suggesting a need for further investigations involving broader samples and extended clinical assessments.
