This randomized controlled research aimed to analyse the occlusion and assist the enamel wear before and after using of the stabilization splints produced by the conventional methods with the fully digitally fabricated stabilization splints.
Research question: Will the fully digital stabilization splint offer significantly better occlusal equilibration and enamel wear compared to the conventional stabilization splint? the primary outcome will be Digital occlusal analysis, and secondary outcome will be enamel wear assessment
18-40 years old
complete dentition
intact tooth
no occlusal disorder
pregnant/lactating women
temporomandibular joint lesions found on clinical palpation or medical imaging examination
dentoalveolar pathology or ongoing treatment related to TMD
jaw opening less than 3 fingers
Parallel
stabilization splint
Devicethe patients will receive a stabilization splint fabricated using a fully digital workflow includes: Intraoral scanning of maxillary and mandibular arches to create a digital model. Jaw tracking using the Zebris JMA system to record mandibular movements. CAD design of the splint using Exocad software. Fabrication of the splint via 3D printing technology. The FD-SS is designed to provide optimal occlusal stabilization, reduce TMJ stress, and minimize enamel wear over 6 months. Or the patient will receive stabilization splint fabricated using conventional methods. The intervention includes: Taking alginate impressions of maxillary and mandibular arches to create plaster casts. Jaw registration using a Lucia jig and semi-adjustable articulator for proper occlusal adjustment. Manual fabrication of the splint using polymethyl methacrylate (PMMA) resin. The C-SS is designed to achieve occlusal stabilization and symptom relief for TMD patients over 6 months.
