The treatment with the lateral plate and simulation of the femoral shaft with bone defects were done using finite element modeling (FEM). The injured area is separated into numerous meshes, and von Mises stress and plate displacements are determined. FEM is used in HAp-based bone tissue engineering, and biomechanical analysis of human tooth and tibia bone. Bone tissue engineering (BTE) to treat osteoporosis is done where the fluid flow is studied using FEM using computational fluid dynamics [123]. In the case of bone scaffolds with a specified shape, the construction of lattices with tuned properties, and numerous mechanobiological models, BTE has been utilized to determine the ideal load [124-132].
