Purpose: This study was performed to investigate mechanical properties of the porous Ti implants according to porosity. Porous Ti implant will be had properties similar to human bone such as microstructure and mechanical properties. Methods: Porous Ti implant samples were fabricated by sintering of spherical Ti powders(below 25 ㎛, 25~32 ㎛, 32~38 ㎛, and 38~45 ㎛) in a high vacuum furnace. Specimen’s diameter and height were 4 ㎜ and 40 ㎜. Surface and sectional images of porous Ti implants were evaluated by scanning electron microscope(SEM). Porosity and average pore size were evaluated by mercury porosimeter. Young’s modulus and tensile strength were evaluated by universal testing machine(UTM). Results: Porosity of Implant was increased according to larger particle size of the powder. Boundary portions of particles are sintered fully and others portions were formed pore. Young’s modulus was decreased by formed porous structure. Tensile strength was decreased according to larger the particle size of the powder, but higher than human bone. Conclusion: If prepared by adjust the porosity of the porous Ti implant will be able to resolve the stress shielding phenomenon.
