![]() IntroductionĪt present, design methods for implant part are mostly based on CT (computed tomography) scan, reverse reconstruction, or forward modeling in design software. The pushout test results show that the designed porous structures have a good osseointegration effect. In addition, the osseointegration status between the implant and the host bone was analyzed by implant experiment. The experimental results show that the apparent elastic modulus of the porous structure scaffold is close to that of the bone tissue, which can effectively reduce the stress shielding effect. The biomechanical simulation experiment was performed using CAE software to simulate the stress and elastic modulus of the designed models. By adjusting the parameters, the apparent elastic modulus of the porous implant model can be regulated. ![]() ![]() Based on the implicit surface function equations, several porous implant models with controlled pore structure were designed. ![]() Implant parts prepared by traditional design and manufacturing methods generally have problems of high stiffness and heavy self-weight, which may cause stress shielding effect between the implanted part and the host bone, and eventually cause loosening of the implanted part. ![]()
