Idiopathic condylar resorption

Weber Ursi, Guilherme Araujo Almeida, Marcos Pitta

Idiopathic condylar Resorption (ICR) also knows as Idiopathic condyliasis, condylar atrophy and progressive condylar resorption, is a challenging condition for both clinicians and researchers. Its clinical manifestation is variable, but in general involves facial imbalance, airway constriction and a Class II molar relationship with an open bite. Diagnosis is based on medical history, clinical and radiological images, with a common chief complaint of worsening of occlusion, facial esthetics, with or without facial pain. The first difficulty it to categorically define upon diagnosing condylar resorption which is the actual condition a patient presents, once a number of local and systemic factors may result in the same clinical appearance. Possible local factors are the ICR, osteoarthritis, reactive arthritis, avascular necrosis, infection and trauma. Systemic factors that may be involved are rheumatoid arthritis, psoriatic arthritis, systemic lupus, Sjogren syndrome, ankylosing spondylitis among others. ICR often is manifested during pubertal growth spurt, mostly in women. Orthodontic or orthognathic surgical patients presenting increased mandibular planes, Class II molar relationship with or without open bite, radiological images of resorbed or malformed condyles, signs and symptoms of TMD should be carefully evaluated before treatment is initiated to determine possible predisposition to ICR and other articular pathologies.
