| Summary: | This study investigates the mechanical performance of bone implants designed as lattice and block plates using parametric Finite Element Analysis (FEA). The objective was to evaluate the effects of varying thickness and radius on the total deformation and equivalent stress under different loading conditions. The results indicated that the lattice plate exhibited a lower total deformation than the block plate across all thicknesses and radii. At 2 mm thickness, the lattice plate deformed 0.35 mm, compared to 0.43 mm in the block plate, and at 5 mm thickness, it deformed 0.30 mm versus 0.52 mm in the block plate. For the equivalent stress, the lattice plate reached a maximum of 68 MPa at a thickness of 3 mm, whereas the block plate peaked at 74 MPa at 2 mm. The highest stress of the lattice plate was 100 MPa at a radius of 3R, compared with 78 MPa for the block plate at 2.75R. The findings indicate that the lattice plate offers superior resistance to deformation and stress, making it a more robust choice for bone implant applications under varying conditions. |
