Abstract

In the present study, three different metals 316L stainless steel, titanium, and magnesium were considered as load-bearing implant materials, and computer-aided design (CAD) and finite element analysis (FEA) were used to investigate the stress distribution in the bone and fixing plates under static load conditions. From the results, it was clearly demonstrated that the reduced von Mises stress in the implant plate and increased stress distribution in the bone reduced the stress shielding when magnesium was used as the implant material compared with 316L steel and titanium. The maximum stress was noticed in the implants, and the minimum stress was observed in the bone in all three cases. Reduced stresses in the implant and increased stresses in the bone implanted with magnesium indicate decreased stress shielding. From the present study, it is demonstrated that the stress shielding effect can be reduced with magnesium implant and suggested as promising candidate for load-bearing implant applications.
