“…One reliable source to necessitate need for biodegradable materials is through requirements of biomaterials. The benefits of biodegradable inserts include the potential for tissue development, a less intrusive fix, continuous body absorption that is nontoxic, stimulation of bone formation, and avoidance of unnecessary surgery [24].…”

Implants play a vital role in a person's life because losing any body part to function less actively, which makes the sufferer uncomfortable. Implants should be both biocompatible and non-toxic to the body is essential to achieve its biocompatibility nature. To create orthopaedic, dental, and surgical implants, biomaterials were divided into three categories: metallic, polymeric, and ceramic. Materials based on polymers indicate their degree of adaptability in terms of sutures, medication delivery, etc. Ceramic materials are known for their high compressive strength and inert behaviour, which combine aesthetic qualities. Metallic biomaterials are enhanced by their high strength and resistance to fracture. One of the most promising techniques for improving a material's mechanical qualities is powder metallurgy. Powder metallurgy involves blending of powders, compaction of blended powder, sintering and mechanical test. Samples with varying compact pressures, sintering temperatures, and sintering times were created using the powder metallurgy process. The aim of the research work is to get the concept of powder metallurgy, biomaterials commercially available for orthopaedic and dental applications, properties of biomaterial and methods to fabricate the material effectively.
