Signs and symptoms of TMD and bruxism in clear aligners wearers: A cohort study

To evaluate signs and symptoms of temporomandibular disorders (TMD) and bruxism in aligner wearers. 87 participants were assessed through virtual questionnaire, while 20 aligner users and 20 controls were clinically followed-up for three months. Cluster analysis identified three patient profiles differing in age, pain, and oral behaviors. No association was observed between aligner use and TMD or self-reported bruxism onset. Aligner and control groups showed reduced oral habits over time, suggesting that clear aligner therapy does not increase the risk of TMD or bruxism but may contribute to greater awareness and control of oral parafunctional behaviors.
