3D-Printed vs Conventional Acrylic Stabilization Splints in Young Adults With Bruxism and Temporomandibular Disorders: A Randomized Trial
Recruiting now · Not applicable
Conditions studied: Bruxism, Sleep
In brief
This randomized clinical study will compare two occlusal splint (night guard) fabrication methods in adults with bruxism (teeth grinding/clenching). Forty-four participants will be randomly allocated to receive either (1) a 3D-printed splint manufactured from a photopolymer resin (Voco V-Print) or (2) a conventional acrylic splint fabricated using standard techniques. Participants will wear the splint during sleep for 3 months and will follow standardized instructions for use and care. At the 3-month follow-up, patient-reported satisfaction and oral health-related quality of life will be assessed using an OHIP-derived questionnaire, and splint wear will be quantified as volumetric material loss (mm³) by 3D scanning and superimposition. The results will help determine whether 3D-printed splints provide comparable patient-centered outcomes and clinical durability to conventional acrylic splints.

Who can join
Age: 18 and older, up to 25. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- 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.
You may not qualify if…
- 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).
