Conclusions: In this clinical case, mandibular repositioning with an anterior repositioning appliance was associated with decreased cortical hyperactivation in auditory/affective regions and disappearance of a major left temporal cluster. Findings support a plausible somatosensory contribution to tinnitus modulation in TMJ disorder and motivate hypothesis-driven prospective studies. Causality cannot be inferred from a single-case design.
