 Metallic biomaterials are engineered systems designed to provide internal support to biological tissues. They are commonly used in joint replacements, dental implants, orthopedic fixations, and stents. However, higher usage of biomaterials is associated with an increased incidence of implant-related complications such as poor implant integration, inflammation, mechanical instability, necrosis, and infections. To improve biointegration, mechanical strength, and flexibility of biometals, various surface and bulk modification strategies are used. These include surface coating, porous structures, and nanotechnology. Additionally, 3D printing technology is being explored for its compatibility with metallic biomaterials.
