Mathematically Designed Bone Implant Scaffolds

Mathematically Designed Bone Implant Scaffolds: "

22618.jpgMathematicians from The University of Queensland are working on a material for bone implants that more closely matches the geometry and properties of the surrounding bone. Traditional titanium implants are much stiffer than human bone and cannot be customized to the patient's anatomy. They used a technique called topology optimisation to design the layout of the material that forms a three-dimensional scaffold. A high-powered laser is then used to melt metal powder into the required shape, layer by layer. The material could be used to create customized implants and features bone pores similar to those found in normal bone. Results were published in the November 2010 issue of Advanced Engineering Materials.
