| Abstract Scope |
This study comprehensively evaluated the mechanical performance and functional longevity of Triply Periodic Minimal Surface (TPMS)-based porous scaffolds for jawbone reconstruction and dental implants. Gyroid, Diamond, and Primitive topologies, which mimic the complex morphology of natural bone, were modeled with varied unit cell sizes and porosities. A two-stage experimental protocol assessed structural integrity under physiological conditions. First, three-point bending tests evaluated the static mechanical response, identifying flexural strength, elastic modulus, and energy absorption capacity. Subsequently, the scaffolds were subjected to cyclic fatigue loading using a chewing simulator to replicate the dynamic intraoral environment. The findings revealed that TPMS topology and geometric parameters critically influence flexural resistance and deformation behavior under simulated masticatory forces. Consequently, this study establishes a foundational guideline for optimizing parametric TPMS configurations to balance mechanical and biomimetic performance in patient-specific maxillofacial implant designs. |
