The treatment of temporomandibular disorders through repositioning splint therapy: a follow-up study

The purpose of this study was to investigate the effectiveness of repositioning splint therapy as a conservative treatment modality for TMD patients. The treatment sequence of 160 randomly sampled TMD patients was monitored in order to assess different aspects of the patients' response to splint therapy. Included among these aspects were the pretreatment symptoms; the treatment duration required for initial and final alleviation of symptoms; the number of patients requiring surgery; and the particular appliance and its wear pattern utilized to maintain the treatment results. The treatment success was based on the remission of symptoms including but not limited to pain to palpation, headaches, earaches, jaw locking, and joint noises. Eighty-nine and four tenths percent (89.4%) of the patients experienced a complete remission of symptoms and did not require any surgical intervention. The average time for initial improvement was 22.3 days, while the average time for complete remission of symptoms was 4.3 months. The results of the study indicate that repositioning splint therapy is an effective treatment modality for the conservative treatment of temporomandibular disorders.
