Assessment of Mechanical Behavior of Ti-Based Biomaterial in Prosthesis Application

Biomaterials encompass a broad range of tissue engineering methods that make it possible to produce materials that can be utilized to repair or replace damaged or missing parts of biological systems. The use of metallic biomaterials in medical implants is complemented by biocompatibility as a prominent aspect. Titanium (Ti) and its alloys are employed as promising implant materials due to their high strength-to-weight ratio and strong biocompatibility. The biocompatibility of Ti-based biomaterials can be improved by altering their mechanical and structural properties, which improves their interaction with the biological environment. Emerging research in advanced Ti-based alloy biomaterials is focused on creating implants with a low elastic modulus while still providing adequate mechanical strength. The major goal is to extend the biomaterial implant's lifespan or eliminate the need for revision surgery, hence improving the patient's quality of life. The present study focuses on Titanium based biomaterial developed with minor alloying elements such as Nb and Zr. Nb and Zr are non-toxic and mechanically sound materials for use in prosthetics. A computational strategy based on the finite element method is utilized to estimate the mechanical properties of the Ti–8Nb–12Zr alloy for biomedical applications. It is concluded that the Ti–Nb–Zr biomaterial with a dominant β phase microstructure exhibits a good combination of mechanical properties and biocompatibility for prosthesis application.
