ABSTRACT
The implantation of a biomaterial can improve the function of its host by its use as a therapeutic device. A biomaterial may augment or replace any tissue, organ, or function of the body [1] and can be composed of a metal, polymer, biological tissue, ceramic, or composite material. A biomaterial's composition is typically chosen as a function of mechanical, optical, and electrical properties that are desired for the implant. The tissue reactions induced by the introduction of a foreign material into a living host depend on the type of implant and site of implantation. The material composition should elicit no toxic, carcinogenic, immunological, or local inflammatory response [2]. The reaction can be favorable and lead to compatibility between the implant and the host tissue. However, the reaction can also be negative and lead to rejection.
