Description:
Over a period of time a number of biomaterials have been developed and are used for hard tissue and joint. Metal Biomaterials gained its importance in recent time for having advantageous mechanical properties, nontoxic behavior, and biocompatibility. But one of the main drawbacks of using metallic implants is that they are bio-inert and inside the body they become encapsulated by dense fibrous tissue. This impedes proper stress distribution at the implant bone interface, which can result in an interfacial failure and loosening of the implant and finally lead to crack or fracture in the adjacent bone. Bone cement (Poly Methyl Methacrylate) can be used to improve the implant fixation but it becomes brittle with time so it gets loosen from the surface as well as it has a poor solvent resistance. Calcium Phosphates, specially Hydroxy-Apatite [Ca 10 (Po 4 ) 6 (OH) 2 ] have been widely used as coating materials on metallic implants due to the bio-ac...
