ABSTRACT
Biomaterials used for implant should posses some important properties in order to long-term usage in the body without rejection. One of the most important property is biocompatibility. These materials are used in different parts of the human body as artificial valves in the heart, stensts in blood vessels, replacement implant in shoulders, knees, hips and orodental structures. Materials used as different biomaterials should be made with certain properties as excellent biocompatibility, superior corrosion resistance in body environment, excellent combination of high strength and low modulus, high ductility and be without toxicity.
