A BIODEGRADABLE IMPLANTS AND A MANUFACTURE METHOD THEREOF

摘要

PURPOSE: A biodegradable implant is provided, which can control organism decomposition speed and supplement low mechanical strength of a porous implant and shock resistance. CONSTITUTION: A biodegradable implant comprises magnesium. The magnesium includes on kind selected from a group comprised of manganese(Mn), iron(Fe), nickel(Ni), and mixture of the nickel(Ni) and iron(Fe). The content of impurity is more than 0 and the same or less 1 parts by weight against magnesium 100 parts by weight. Therefore, the organism decomposition speed can easily controlled, the interface force between the intensity and the bone tissue are improved, and the bone formation rate can be improved.
