Unit cells used for implant modeling and the models of implants. Left: (a) UC001—the unit cell built on the basis of tetrahedral diamond structure (rib thickness = 0.4 mm, cell length (L) = 2.3 mm, cell width (W) = 2.3 mm, cell height (H) = 1.7 mm); (b) UC00202—the cell built on the basis of the UC001 unit cell by removing open ribs (rib thickness = 0.7 mm, L = 1.6 mm, W = 1.6 mm, H = 2.3 mm); (c) UC003—the cell built by replicating the UC002 unit cell along the X and Y axes by a factor of 2, with the offset along Z-axis by H/2, and along X-axis by W/2 (rib thickness of 0.7 mm, L = 3.5 mm, W = 3.5 mm, H = 3.8 mm); (d) UC004—the cell built by compressing the UC003 unit cell along X and Y axes by the factor of 2 (rib thickness =0.3 mm, L = 2.0 mm, W = 2.0 mm, H = 4.1 mm). Right: (a) BI001—the wireframe built by replicating the UC001 unit cell along three coordinate axes, by a factor of 3 along X and Y axes, and by a factor of 5 along Z-axis; (b) BI002—the UC002 unit cell is replicated by a factor of 2 along X and Y axes, and by the factor of 4 along Z axis; (c) BI003—the UC003 unit cell is replicated by a factor of 1 along X and Y axes, and by a factor of 3 along Z-axis; (d) BI004—the UC004 unit cell is replicated by a factor of 3 along X, Y, and Z axes [125].
