Selective Voronoi tessellation as a method to design anisotropic and biomimetic implants

The geometry of a metallic scaffold is important for the success bone implants, where introduction porosity can reduce stress shielding effects and allow tissue integration. In this work, porous scaffolds were designed to closely mimic natural structure trabecular using selective Voronoi tessellation with preferential seeding. A workflow generate these structures introduced, voided regions seeds in starting volume create texture during polyhedral expansion, resulting modified strut orientation implant. Anisotropy was digitally characterized by mean-intercept length star distribution measurements determine similarity orientation. This work demonstrates that an effective method biomimetic increased anisotropy tunable architecture three dimensions as suitable alternative patient-derived geometries.
