Investigation of the effects of different lattice structures on mechanical strength and biocompatibility in tibial implants using the finite element method
This study investigates the impact of six distinct lattice structures (Gyroid, Diamond, Schwarz, SplitP, Lidinoid, and Kelvin) on the mechanical performance and biocompatibility of CoCrMoW-based tibial implants. Finite element analysis was conducted using nTopology to simulate compression tests under a 3100 N load, evaluating important parameters such as stress, strain, displacement, reaction forces, mass, volume, and porosity. Global stiffness values were calculated based on the test results. The effect of lattice structure designs on global stiffness properties was determined. The results show that lattice structures improve the mechanical strength and biocompatibility of tibial implants and reduce the mass and stiffness value, consequently improving osseointegration and long-term stability.
