Introduction: The resorption of the temporomandibular joint (TMJ) can occur, among some clinical situations, after orthognathic surgery in specific patients. This pathology affects a group with common characteristics, female patients, carrying of Class II dentofacial deformity, that had temporomandibular joint dysfunction (TJD) previously to the orthodontic and surgical treatment and that were operated by means of bimaxillary osteotomy involving great mandibular advancements. It is imperative that this group of patients receives adequate cares, like the treatment of the TJD’s symptoms before the orthodontic/surgical procedures and monitoring. The main goal in these cases is to prevent or at least to minimize this resorption, that is an instability that leads to the relapse of the deformity after orthodontic and surgical treatment. Aim: To review the literature about this issue and report a clinical case of progressive condylar resoption.
