3D-Printed vs Conventional Acrylic Stabilization Splints in Young Adults With Bruxism and Temporomandibular Disorders: A Randomized Trial
Turkey (Türkiye)44 participantsStarted 2026-01-12
Plain-language summary
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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
