Table 6 Mechanical analysis of the screws: the axial displacements of screws of commercial reconstrction plates, 12 mm-height reconstrction plates, 16 mm-height reconstrction plates and 20 mm-height reconstrction plates under INC and MOL-L. * ”L” represents the screw fixed to the meial bone tissue. “L1”-”L6” is from bottom to top and from left to right; ”R” represents the screw fixed to the distal bone tissue. “R1”-”R6” is from bottom to top and from left to right

From: Finite element analysis and clinical application of 3D-printed Ti alloy implant for the reconstruction of mandibular defects
