Microscopic Acid-Induced Degradation and Elemental Release From Thermoformed and 3D-Printed Orthodontic Aligners in a Simulated Gastric Environment
{{output}}
Clear aligners have revolutionized orthodontic treatment, yet concerns are rising about microplastics (MPs) and nanoplastics (NPs) released from these devices through mechanical wear and chemical degradation. Once ingested, these particles may undergo structur... ...
