Biomechanical complications, such as stress shielding, bone resorption, and reconstruction failure, are prevalently associated with solid titanium mandible plates. This study evaluates the potential of metamaterial designs porous gyroid microarchitectures, to enhance biomechanical stimulation mitigate these complications. A novel plate is compared plates, both patient-specifically designed fabricated from Ti6Al4 V alloy. Stress shielding assessed through photoelasticity experiments validated finite element analysis (FEA). Transparent models loaded incrementally (0-1000 N) analyze distributions in implants, screws, segments. The reduces concentrations distant mandibular regions defect, while increasing around screws near favoring local mechanical stimulation. FEA confirms improved load distribution (p = 0.003). However, exhibited a lower load-bearing capacity, failing at 775 N, withstood 1800 N without failure. Yet, design effectively reduced thereby enhancing function critical regions. Hence, despite their they can, potentially, preserve integrity prevent implant failure that should be future (pre-)clinical studies.
