Abstract
The aim of this research was to study if changes in condyle position in temporomandibular disorders (TMD) patients could be a factor that is affected by resilient appliance therapy and if it influences the treatment outcome. The study investigated 48 patients randomly assigned to a treatment group (T group = 21 patients, using resilient appliance) or a control group (C group = 27 patients, using nonoccluding appliance). Changes in the condyle-fossa relationship (with and without the appliance) were determined in an MRI examination. Ten weeks after treatment, the treatment outcome was measured. The results showed that with the appliance, change in condyle position occurred in 76% of the T group and 22% of the C group (p<0.001). Sixty-seven percent (67%) of the T group and 44% of the C group experienced a successful treatment outcome. Treatment outcome was not related to changes in condyle position in patients with TMD pain.
