For edentulous patients with denture repair again, who use the old dentures for many years, most of their jaw relationships is characterized as the inconformity between intercuspal position and muscular contact position. If not to adjust the jaw improper position, it can eventually induce or aggravate temporomandibular joint disorder syndrome. Therefore, to determine the appropriate jaw relationship is the way to prevent and treat temporomandibular joint disorder syndrome, and the key to do the restoration successfully. In this paper, the research progress on jaw relationship, which includes the vertical dimension, the horizontal relation, and the hinge axis relation were reviewed.
