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.
