Abstract
The difference in material properties between bone and implants might cause the bone surrounding the implant to weaken as a result of stress shielding, which prevents the required stress for bone remodeling. Integrating lattice structures into implants is an effective method to reduce the negative effects of stress shielding. This study investigates the characteristics of three lattice structures (Diamond, Gyroid, and Primitive) with different levels of porosity ranging from 25% to 95%. The lattice structures are standardized for representation, and finite element analysis is performed on the C5–C6 segment of the cervical spine using the implant model. The VIKOR Fuzzy Multi Decision Making technique is used to maximize stress levels in the interbody fusion cage and identify the best appropriate lattice structure. The findings suggest that Diamond and Gyroid structures exhibit superior performance compared to the Primitive lattice, with an ideal porosity range of 5% for cage implants.
