3D-Printed vs Conventional Acrylic Stabilization Splints in Young Adults With Bruxism and Temporomandibular Disorders: A Randomized Trial

Inclusion Criteria: * Adults (≥18 years) diagnosed with bruxism (sleep and/or awake bruxism) based on clinical assessment and patient report. Indication for an occlusal splint and willingness to wear the splint during sleep for 3 months. Ability to provide written informed consent and to attend scheduled follow-up visits. Exclusion Criteria: * Current or recent use of an occlusal splint within the last 6 months. Ongoing orthodontic treatment or planned major dental treatment during the study period that could affect occlusion. Severe temporomandibular disorder requiring active treatment (e.g., acute pain, limited mouth opening) or other conditions that could contraindicate splint use. Extensive untreated dental disease requiring immediate care (e.g., severe periodontal disease, multiple untreated caries). Systemic/neurologic conditions or medications that may significantly affect bruxism or neuromuscular function (as judged by the investigator).
