- W4386523206 abstract "Regenerative biomaterials for musculoskeletal defects must address multi-scale mechanical challenges. We are developing biomaterials for craniomaxillofacial bone defects that are often large and irregularly shaped. These require close conformal contact between implant and defect margins to aid healing. While we have identified a mineralized collagen scaffold that promotes mesenchymal stem cell osteogenic differentiation in vitro and bone formation in vivo, its mechanical performance is insufficient for surgical translation. We report a generative design approach to create scaffold-mesh composites by embedding a macro-scale polymeric Voronoi mesh into the mineralized collagen scaffold. The mechanics of architected foam reinforced composites are defined by a rigorous predictive moduli equation. We show biphasic composites localize strain during loading. Further, planar and 3D mesh-scaffold composites can be rapidly shaped to aid conformal fitting. Voronoi-based composites overcome traditional porosity-mechanics relationship limits while enabling rapid shaping of regenerative implants to conformally fit complex defects unique for individual patients." @default.
