Idiopathic Condylar Resorption, Therapeutic Management

Progressive condylar resorption (PCR) is a degenerative condition affecting the structures of the temporomandibular joint (TMJ). This disorder may involve one or both joints. PCR remains a poorly defined condition, and there are limited guidelines for its management. This study presents 20 patients diagnosed with PCR who were treated with a lower orthopedic splint featuring asymmetric posterior contacts, individually adapted for each case. All patients were female, with a mean age of 20.7 years. Eighty percent had a history of previous orthodontic treatment, and three patients had undergone prior orthognathic surgery. Bilateral PCR was observed in 75 % of the cases, and 90 % presented anterior open bite. During the first three months of treatment, all patients showed improvement in TMJ signs and symptoms. The occlusal orthopedic splint used in this case series appears to be a useful non-invasive alternative for improving TMJ morphology and function in patients with PCR.
