Biomaterials are widely used to formulate artificial organs. Biomaterials can be adopted from nature or prepared in the laboratory by using different chemical processes with incorporation of metals like polymers, ceramics or composite materials and used in medical applications as an augments, or replacer of natural function. Biomaterials are mostly applied in Joint replacements, dental applications, Blood vessel prostheses, drug delivery, vascular grafts, Stents, Nerve conduits, contact lens and in surgery as transplant material. Material science focuses on application of biomaterials and tissue engineering constructs in medical or dental implants, prostheses and body transplanting devices. Biomaterials can be metals, ceramics, polymers, glasses, carbons, and composite materials. Generally biomaterials are integrated into devices or implants.
These biomaterials must be compatible with the transplanted body, Since, biomaterial may elicit the immune response in the transplanted organism or it may integrate with the tissue. So it is important to follow careful design in order to have accurate fit and beneficial effect in that specific anatomical area of action. Behavior of the biomaterial depends on property of the material on various environments, physical and chemical conditions, Prior Understanding of biomaterial property and design is important for the successful performance of a medical implant.
