Idiopathic condylar resorption (ICR), also known as idiopathic condylysis or condylar atrophy, and progressive condylar resorption (PCR), is a poorly understood progressive disease that affects the temporomandibular joint (TMJ) with multifactorial factors leading to severe mandibular retrognathism and anterior open bite. It is difficult to distinguish the exact causes for each individual. Different diagnostic methods and different treatment options can be chosen for different phases. In this report, we present a camouflage treatment with temporary anchorage devices (TADs) for a skeletal Class II open bite with ICR. The goal of improving facial profile and reconstructing of occlusion was achieved. Comprehensive review of ICR was presented in this case report.
