Risk Factors in the Initiation of Condylar Resorption

Progressive condylar resorption is a process that involves the temporomandibular joint (TMJ) and the occlusion. During growth, condylar resorption may decrease the projection of the mandible and be unrecognized as the source of a Class II malocclusion. After growth completion, as the condyle resorbs, the occlusion becomes progressively Class II, with or without open bite. Broadly speaking, condylar resorption is initiated or maintained by a combination of systemic factors and any form of TMJ compression, including pressure resulting from dental treatment.
