Temporomandibular disorder associated with sacroiliac sprain.

A case of the external derangement-type temporomandibular disorder (TMD), temporarily relieved following chiropractic sacro-occipital technique (SOT) treatment, including SOT category II blocking to reduce sacroiliac sprain, is presented. Symptom exacerbation midway through the course of treatment followed additional dental work; symptom remission followed additional SOT treatment. Freedom from symptoms is maintained with a 3-wk treatment interval. There appears to be a cause-effect relationship between external derangement-type TMD and sacroiliac sprain. Concurrent, coordinated chiropractic and dental treatments may improve the success rate of TMD resolution.
