Abstract
Idiopathic condylar resorption (ICR) is a localized, non-inflammatory degenerative disease of the temporomandibular joint (TMJ) characterized by osteolysis that leads to the destruction of the mandibular condyles. The etiology of ICR is still unknown. Possible risk factors have already been identified, including orthognathic surgery. This condition is more common in women than men. Radiographic study in these cases indicates a diminished condylar head volume, decreased ramus height, change in condylar shape, and progressive Class II basal bone relationship. Computed tomography (CT) and cone beam computed tomography (CBCT) are suitable for diagnosing initial ICR manifestation and progression. Drugs and occlusal splint therapy represent a conservative form of treatment. Arthroscopy and arthrocentesis can help reduce pain and improve joint function. In advanced stages of ICR, total joint replacement may be necessary. The approach to treating ICR cases should be individualized and based on the extent of the disease process. There are a number of patients with ICR who are best treated with total joint replacement (TJR).
