“…However, the accurate modeling of bone-related organs using finite element modeling (FEM) methods is challenging due to their inherent inhomogeneous and anisotropic characteristics [1,4,37,58]. As a result, almost all previous studies consider the implanted bone to be isotropic, homogeneous, and linearly elastic [3,4,25,41,[59][60][61][62][63]. However, such a simplification results in significantly lower stress predictions for the peri-implant bone than those observed in practice [8].…”

Variations in the implant thread shape and occlusal load behavior may result in significant changes in the biological and mechanical properties of dental implants and surrounding bone tissue. Most previous studies consider a single implant thread design, an isotropic bone structure, and a static occlusal load. However, the effects of different thread designs, bone material properties, and loading conditions are important concerns in clinical practice. Accordingly, the present study performs Finite Element Analysis (FEA) simulations to investigate the static, quasi-static and dynamic response of the implant and implanted bone material under various thread designs and occlusal loading directions (buccal-lingual, mesiodistal and apical). The simulations focus specifically on the von Mises stress, displacement, shear stress, compressive stress, and tensile stress within the implant and the surrounding bone. The results show that the thread design and occlusal loading rate have a significant effect on the stress distribution and deformation of the implant and bone structure during clinical applications. Overall, the results provide a useful insight into the design of enhanced dental implants for an improved load transfer efficiency and success rate.
