“…1 Idiopathic condylar resorption (ICR), also known as progressive CR or condylar atrophy, can lead to skeletal and occlusal instability, as well as facial deformities, temporomandibular disorders, and pain. According to Arnett et al, 2,3 there are 3 groups of factors that could cause or contribute to the establishment of CR: malocclusion or improper bite, with premature contacts, which can generate a condylar compression; systemic pathologies (osteoarthritis, hyperparathyroidism, rheumatoid arthritis, hormones) and factors related to condylar anatomy, as well as condylar abnormalities caused by syndrome, trauma, or iatrogenic events.…”
