Titanium frameworks for complete arch implant\u2010supported fixed dental prostheses, which incorporated three distinct TPMS lattice structures (Schwarz, Diamond, and Lidinoid) with variable cell wall thicknesses, were designed using topology optimization software. A total of 36 optimized framework designs were analyzed by finite element analysis under vertical and oblique loading (200 N) at the canine, premolar, and molar (cantilever) regions. A solid, non\u2010optimized titanium framework was the control group. von Mises stress (MPa), maximum displacement (\u00b5m), reaction forces (N), and weight reduction ratios (%) were analyzed. Statistical analyses were performed with ANOVA and Tukey's post hoc test (\n                      <jats:italic>\u03b1<\/jats:italic>\n                      = 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All topology\u2010optimized frameworks achieved &gt;30% weight reduction, with the Diamond lattice structure demonstrating the highest reduction of 39.92\u00a0\u00b1\u00a02.60 (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001). Although optimized frameworks exhibited higher displacement and stress values than solid controls because of increased flexibility, the peak stress values (190\u2013210\u00a0MPa) remained significantly below the yield strength of titanium. Optimized frameworks generated significantly lower reaction forces than solid controls under canine and premolar loading, indicating an energy\u2010absorbing effect.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Topology optimization created a semi\u2010rigid framework that incorporates the shock\u2010absorbing benefits of polymers while maintaining the inherent fracture resistance of metallic alloys.
