Abstract
AN important aspect of materials science is the development of new porous solids for prosthetic applications, especially for synthetic teeth and bone replacement. To be acceptable, such biomaterials must meet some rather demanding specifications, among which are high strength and compatibility with-body fluids or tissues. The structure of the porous medium is important as the pores must be both interconnected and have the proper size, shape and uniformity to permit ingrowth and attachment of body tissue. The problem lies in attaining the optimum combination of these properties to yield a high strength to weight ratio material, with a microstructure which best facilitates firm attachment of tissue. Ideally these materials should be easily machined or fashioned into particular shapes for different individual implants, and should be relatively inexpensive.
