Abstract: A normal articular disc-condyle relationship is important to the health of temporomandibular joint. The change of articular disc-condyle is of great clinical significance. Magnetic resonance imaging (MRI) is considered as the gold standard of temporomandibular joint disc-condyle relationship disorder and soft tissue morphology imaging, and is widely used in the evaluation of temporomandibular joint characteristics, diagnosis assistance and treatment choice. At present, most studies show that the early stage of temporomandibular joint disorder(TMD) may be characterized by anterolateral displacement of the joint disc and changes in the shape of biconcave. Changes in the shape and position of the articular disc further lead to changes in the length, height and rotation angle of condyle, which makes the disease develop to a more serious stage. The position and shape changes of joint disc and the anatomical changes of condyle in TMD patients are related to the displacement of joint disc, which is considered to be the most common cause of TMD.
