Angulation and prominence of the posterior slope of the eminence of the temporomandibular joint in relation to disc position.
A steep articular eminence has been proposed as an aetiological factor in internal derangement of the temporomandibular joint. Arthrograms of 20 joints each of three groups, superior disc position (SDP), anterior disc displacement with reduction (ADDWR) and anterior disc displacement without reduction (ADDWOR) were compared. No correlation was found between a steep articular eminence and anterior disc displacement. The posterior slope of the articular eminence of the joints with ADDWOR was significantly less prominent than in those with SDP and ADDWR.
