Design of Implant Prosthesis for Bone Injury Repair Considering Stress Shielding Effect
文献摘要：
The failure of bone injury repair surgery is mostly due to the stress shielding effect caused by the difference of elastic modulus between the implant prosthesis and human bone, result-ing in a great damage to patients. To solve this problem, in this study, the influencing factors of the elastic modulus of implant prosthesis were investigated, the relationship between the elastic modulus of the implanted prosthesis and the influencing factors was analyzed, and then a design method of the implant prosthesis to reduce the stress shielding effect by adjusting the unit module to control the elastic modulus was established. This method was used for the biomechanical simula-tion to simulate the displacement and stress distribution between the implant prosthesis and the surrounding bone tissue, and then the reliability of the method was verified. The implant prosthe-sis with an elastic modulus consistent with that of the experimental dog bone was made by this method, and used for the animal experiments. The effects of implant prosthesis with different mod-ulus on the growth of surrounding bone tissue were observed, and at the same time, the reliability of the implant design method and the results of biomechanical simulation were verified. It is con-firmed that this method can effectively reduce the stress concentration of implant prosthesis by more than 15.4％ and increase the growth of bone tissue by more than 21％.
