| Abstract | In using finite element analysis on bone-implant models, the static loading condition is the peak load of dynamic loading condition under daily activities. Dynamic loading will affect the strain distribution on the bone and stress distribution on the implant. In this research, the normal bone, bone inserted with load-bearing device and bone inserted with load-sharing device under static and dynamic loading conditions were analyzed to compare the stress distribution on the implant and strain distribution on the bone. The results show that the maximum difference of equivalent total strain between static loading condition and dynamic loading condition in normal bone is less than 20%, in bone inserted load-bearing device is less than 12%, and in bone inserted load-bearing device is less than 30%. The maximum difference of von Mises stress between static loading condition and dynamic loading condition in load-bearing device is less than 3% but exceeds 105% for load-sharing device. The static loading and dynamic loading conditions can be used interchangeably in analyzing normal bone and load-bearing devices while dynamic loading condition is considered more suitable for load-sharing devices in finite element analysis of bone-implant models. |
