Metallic implants with properties and latest production techniques: a review

ABSTRACT

Biomaterials are the most emerging and promising field in total joint arthroplasty (TJA) as these materials gain their popularity in the ageing population. With steep growth in population and an unhealthy lifestyle, human life expectancy has decreased. Many people suffer from diseases such as arthritis, joint pain, bone fracture because of ageing issues, overweight, sudden shock, etc. Extensive research is made in a field of materials engineering to find out the most optimal material, which can quantify human life in terms of longevity and quality. The paper discusses the possible projected areas of implants in the human body and focuses on human anatomy and its load-bearing capacity for designing any derailed organ with implants. Besides, this paper also discusses the different biocompatible materials and overall superiority of titanium-based bio-implants in terms of corrosion resistance, osteolysis, tribology, etc. Overall an attempt is made to give a brief insight related to causes of dysfunctional bones, remedies to use bio-implants, processing through additive manufacturing and its further possibilities to bring out the most favourable and superior biocompatible implant.
