Which scientific discipline best links the use of titanium and plastics in artificial bone and joint replacements?

The scientific discipline that best links the use of titanium and plastics in artificial bone and joint replacements is biomaterials science. This field focuses on the development and application of materials that interact with biological systems, ensuring biocompatibility and functionality. Titanium is often chosen for its strength and corrosion resistance, while plastics, such as polyethylene, are used for their flexibility and wear resistance, making them ideal for joint replacements. Together, these materials aim to mimic natural bone and joint properties while promoting healing and integration within the body.
