Effect of occlusal splints on TMJ symptomatology

The clinical response of TMJ symptomatology to full-coverage occlusal splints, when used as the only means of treatment, was evaluated. The symptomatology recorded during the last postoperative visit was compared to the initial visit. The response of the different symptoms to the use of the occlusal splint was analyzed statistically using a chi-square test. A statistically significant difference (p = .03) was only found when comparing those groups having only pain or dysfunction symptomatology. The response favored the remission of pain. However, every symptom was improved with the use of an occlusal splint. It was concluded that: 1. Both pain and dysfunction symptomatology will benefit from the occlusal splint therapy. 2. The pain response will be significantly better than the dysfunction response when the patient is treated with an occlusal splint. 3. Eighty percent of the patients suffering from a TMJ syndrome will improve or be cured when the only form of treatment is the use of a full-coverage occlusal splint.
