Displacement and strain distributions of representative 3D CAD renderings using a 4-noded linear tetrahedral mesh of 52636 elements of both biconcave and flat TMJ shape-specific constructs having Er = 25 kPa, Poisson’s ratio = 0.2, and a load of 1 g. Nodes at the bottom of both models were constrained in the Z-direction, and the passive axial load was modeled as a pressure distribution across an area of 54 mm2 on the top surface of the models. This set of parameters resulted in 0.5%, 0.7%, and −0.9% strains in the XX, YY, and ZZ directions, respectively, within the middle zone of the biconcave model, and 0.1%, 0.1%, and −0.7% strains in the XX, YY, and ZZ directions, respectively, across the top surface of the flat model.
