The aim of this study was to evaluate stress distributions in the temporomandibular joints (TMJs) with disorders (TMDs) for comparison healthy TMJs. A model mandible and normal TMJs developed according CT images. interfaces between discs articular cartilages were treated as contact elements. Nonlinear cable elements used simulate disc attachments. Based on model, seven models various TMDs established. maximum stresses anterior, posterior, medial lateral displacement (ADD, PDD, MDD LDD) 12.09, 9.33, 10.71 6.07 times magnitude identically disc, respectively. posterior eminences ADD, MDD, LDD, relaxation attachments perforation 21, 59, 46, 13 15 greater than could cause increased eminences.
