Abstract: Patients with malocclusion have abnormal dental dysfunction and abnormal appearance, which even cause psychological problems. The patients are urgent to solve the problem. The treatment of skeletal malocclusion is mainly treated with orthodontic-orthognathic surgery, ie preoperative orthodontic- orthognathic surgery-postoperative orthodontic procedure. Sagittal split ramus osteotomy (SSRO) is a common clinical orthodontic operation which can realize the extension and retrogression of mandibular position. It has been widely used in the treatment of mandibular misalignment. However, as a traumatic surgery, SSRO may affect the structural position, function, and joint symptoms of the temporomandibular joint. Therefore, this paper reviews the research progress of SSRO on TMJ.
