Occlusal splint plus Rocabado jaw exercises for temporomandibular disorder

The Effects of Occlusal Splint and Exercise in Individuals With Temporomandibular Disorders

Not applicable Interventional Acibadem University · NCT07507734

This project will see if adding daily Rocabado jaw exercises to nightly occlusal splint use helps adults (18-65) with temporomandibular disorder reduce pain, improve jaw movement, and change muscle mechanical properties.

What this trial studies

This is a two-arm, randomized, controlled prospective trial comparing nightly occlusal splint therapy alone to occlusal splint therapy combined with the Rocabado 6x6 exercise protocol in adults with TMD. Participants will be stratified by age, gender, and occupation and will undergo baseline and 4-week follow-up assessments. Measured outcomes include patient-reported pain and function (JLFS-20, CF-PDI, GCPS-2.0), jaw range of motion, pain pressure thresholds, and objective muscle mechanical properties of the masticatory and neck muscles. The exercise-plus-splint group will perform six daily sessions of six Rocabado exercises while both groups use a nightly occlusal splint for four weeks.

Who should consider this trial

Good fit: Adults aged 18-65 with a clinical and radiological diagnosis of TMD and at least three months of TMJ pain who can attend clinic visits in Istanbul and perform the daily exercise regimen are ideal candidates.

Not a fit: Patients with intra-articular degenerative joint disease, recent TMJ or cervical surgery, rheumatic disease, TMJ instability or fracture, cognitive impairment, or chronic neuropathic facial pain are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the combined approach could provide a simple, low-cost way for patients to reduce TMD pain and improve jaw function more effectively than splint therapy alone.

How similar studies have performed: Previous studies show occlusal splints and targeted exercise programs can each improve TMD symptoms, but randomized comparisons of the combined splint-plus-exercise approach versus splint alone, particularly including muscle mechanical property outcomes, are limited.
