The cause of TMJ syndrome is multifactorial and may include chronic teeth grinding, trauma to the area, arthritis in the joint, or displacement of the articular disc that is present between the mandible and the temporal bone.
Among the components of TMJ are the bone portions (mandibular fossa of the temporal bone, mandibular condyle), articular cartilage, joint capsule, articular disc, synovial membrane and its ligaments (Drake et al.; Standring; Tortora & Derrickson).
The areas with the minimum principal stresses, which get low negative ratings in the articular disc, were observed in the anterior area of the surface of the articular disc facing the condyle in the FRD and screwed-FRD models.
They occur because the physiological relationship between the articular disc and the condyle head changes.
ID refers to an abnormal positional relationship of the articular disc in relation to the mandibular condyle and the articular eminence in the glenoid fossa, in the temporal bone [5, 10, 11, 14].

In addition, we also discussed the alteration of the articular disc material to show the impact of this alteration in the calculation of stress and strain.
This incongruence is passed by cartilaginous articular disc which is able to move together with mandibular condyle along the articular eminence.
Based on Axis I, the individuals were divided into three situations, including muscular temporomandibular dysfunction, displacement of the articular disc, and general conditions of temporomandibular articulation (Schiffman et al., 2014).
At the time of surgery, all patients included in the series were found to have a central tear of the articular disc as well as a peripheral ulnar detachment.
It was also observed that some muscle fibers of the masseter temporal and lateral pterygoid muscles entered and dispersed inside the articular disc in which the elastic fibers were dense.
(2,9) The TFCC is composed of a rich peripheral arterial supply at the outer 10-40% of the articular disc, and a near avascular central triangular articular disc lying between the ulnar head, lunate, and triquetrum.
