Idiopathic Condylar Resorption

Idiopathic condylar resorption (ICR), alternatively called progressive condylar resorption, is an uncommon aggressive form of degenerative disease of the temporomandibular joint seen mostly in adolescent and young women. ICR occurring before the completion of growth results in a shorter mandibular condyloid process, ramus and body, compensatory growth at the gonial angle and coronoid process, as well as an increase in anterior facial vertical dimension. Management options discussed include oral appliances, orthodontics, medical management, orthognathic surgery with and without disc repositioning, and alloplastic temporomandibular joint replacement.
