title: Short-term treatment of a resilient appliance in TMD pain patients: a randomized controlled trial.
abstract: To investigate the short-term efficacy of a resilient appliance in patients with temporomandibular disorders (TMD) suffering from pain, 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' TMD pain at worst, according to the Visual Analog Scale (VAS), decreased by at least 30%. One additional treatment outcome was reduction of characteristic pain intensity. Number needed to treat was measured on the basis of primary treatment outcome at 10 weeks. At baseline, patient characteristics and TMD pain did not differ between the groups. There were no significant differences between groups regarding a 30% reduction in VAS-reported TMD pain at worst at 10 weeks' follow-up; 61% in the treatment group and 46% in the control group. After 6 and 10 weeks of treatment, CPI decreased in both groups. Number needed to treat was 9.1 for both the resilient and the control appliance therapy during 10 weeks. There was no statistically significant difference between the resilient appliance and the non-occluding control appliance in reducing TMD pain from a short-term perspective.
