Objectives: To investigate long-term efficacy of a resilient appliance in patients with pain due to temporomandibular disorders (TMD). Methods: A randomized, controlled trial was performed in 80 recruited TMD pain patients. They were randomly allocated to one of two groups: treatment with a resilient appliance or treatment with a hard, palatal, non-occluding appliance. The primary treatment outcome measure was judged positive when patients' characteristic pain intensity decreased by at least 30%. Additional treatment outcomes were physical functioning, emotional functioning and headache. Number needed to treat was measured on the basis of primary treatment outcome at 12 months. Results: At 12 months follow-up 50% of the patients in the treatment group and 42% in the control group had a 30% reduction of characteristic pain intensity, when calculated as intent to treat analysis. Jaw function improved in both groups at 6 and 12 month follow-up. Emotional function improved in both groups at 6 months follow-up; an improvement concerning grade of depression was found in the control group at 12 month. Headache decreased in both groups at both follow-ups. There were no statistically significant differences found regarding primary and additional outcomes between groups at 6 and 12 months follow-up. NNT was 14 when calculated on a 30% reduction of CPI at 12 months follow-up. Conclusion: There was no statistically significant difference between the resilient appliance and the non-occluding control appliance in reducing TMD pain, physical functioning, emotional functioning and headache in a 12 months perspective.
