The temporomandibular ligament supports the joint when high posterior forces occur and limits the posterior displacement of the mandible. It also constraints the condyle during opening (Osborn et al. 1989). It is composed of two bundles of fibers which attach at the zygomatic arch and the neck of the mandible. The lateral pterygoid muscle attaches to the condyle, and in the majority of cases, also directly to the articular disc. The lateral pterygoid muscle is the main responsible for the anterior incursion of the condyle and the disc.

For the simulation, the following three contact models have been imposed:Fixed: ground to temporal boneFrictionless: articular disc to glenoid fossa, teeth to MADBonded: articular disc to condyle, temporomandibular ligament to temporal bone, temporomandibular ligament to mandible, sphenomandibular ligament to temporal bone, sphenomandibular ligament to mandible, stylomandibular ligament to temporal bone, stylomandibular ligament to mandible, periodontal ligaments to mandible, periodontal ligaments to teeth.

According to the previous study (Liu et al. 2008, 2016), contact elements were used to simulate the interaction between the disc and the cartilages of the condyle and the temporal bone, with friction coefficient 0.001. Nonlinear cable elements were used to simulate the temporomandibular ligament, sphenomandibular ligament and stylomandibular ligament with corresponding stiffness values (Liu et al. 2008; Muralidhar et al. 2000). In addition, the discal attachments, including temporal anterior attachment, mandibular anterior attachment and bilaminar zones, were also modeled as nonlinear cable elements with referenced stiffness (Chen and Xu 1994; Liu et al. 2008). The model was named as PRE.
