Clear Aligners and Bruxism: A Systematic Review

Current evidence on the relationship between clear aligner therapy and bruxism remains limited and heterogeneous. Most studies suggest a neutral effect, with occasional reductions in tonic contractions or symptom improvement, but also reports of increased phasic activity or self-reported bruxism. Overall, aligners cannot yet be classified as protective or harmful, highlighting the need for standardised, high-quality studies to clarify their role in bruxism management.
