Computational Models of Magnesium Medical Implants Degradation: A Review

Abstract Magnesium is attracting the attention of researchers from medical field especially implant material due to its properties, including but not limited to degradation and biocompatibility. Many chemical and physical reactions are considered to play a part in the procedure of magnesium degradation and influence the bio-tissue. To design and analyze magnesium implants, it is important to fully consider the factors that will affect the degradation and the impacts on the mechanical property as well as the in-vivo environment. Computational model gives another way to capture and analyze the in-vivo degradation behavior of the magnesium besides experiment. A review of the current computational models which could be used in study of magnesium medical implant is presented here, with the main mechanisms and accomplishments of each model highlighted.
