Comparative Finite Element Analysis of 3D Printable Dental Implants with Various Lattice Structures

Abstract:- Purpose: This study looks at how well lattice-structured titanium dental implants—Gyroid, X-Cell, and Diamond designs—work when made with two different levels of porosity (20% and 40%) and compared to a totally solid implant. Methods: We used Finite Element Analysis (ANSYS) to model physiological axial loading. The most important numbers were the maximum von Mises stress, the maximum deformation, and the average deformation for all implant types. Results: Higher porosity always lowered peak stress but raised deformation, showing a trade-off between stiffness and compliance. The X-Cell structure had the best mechanical balance at 20% porosity, while the Gyroid design was better at handling stress with little deformation. Diamond, on the other hand, had too much compliance at 40% porosity, which made it less useful under high load. Conclusion: The mechanical behaviour is greatly affected by the lattice geometry and porosity. X-Cell (20%) and Gyroid (20%) arrangements look like they could be good ideas for implants that work well mechanically and respond to biological signals. The results show how important it is to optimise the structure of next-generation dental prosthesis. Keywords :- Lattice Implant, FEA Simulation, Porosity, Titanium Implant, Biomechanics
