Summary

This study looks at a dental procedure called occlusal equilibration for people with long-term jaw pain (TMD). Researchers want to see if it still reduces pain 10 years later compared to a fake treatment. About 110 adults who had the procedure at a university clinic will be followed up to measure pain and jaw movement.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Previous occlusal equilibration for TMD pain at the University of Santiago. * Be diagnosed with joint and/or muscle TMD pain according to DC/TMD. * Be aged 18-85 years. * Be completely dentate with normal or adequately restored occlusion (fixed crowns/bridges allowed). * Report pretreatment significant TMD pain (VAS/NRS 4-9 on a 0-10 scale). * Have actively sought treatment and been referred to the University/Hospital service. * Have undergone ≥6 months of prior conservative therapy. Exclusion Criteria: * Psychosis, major depression, substance abuse, or cognitive impairment. * Opioid (morphine-derivative) addiction. * Ongoing litigation or disability claims related to chronic pain. * Dental professional background. * Orthodontic treatment within the last 2 years. * Severe tooth mobility (grade 3). * Other pain conditions indistinguishable from or more severe than TMD pain. * Additionally, patients will be excluded if minimally invasive occlusal adjustment cannot achieve equilibration, defined by: 2 mm discrepancy between maximal intercuspation and centric occlusion, and/or 4 mm total interarch discrepancy (≥2 mm on one side) in defined premolar/molars reference points, measured intraorally using a Boley gauge.
