| Abstract Scope |
Septic loosening of orthopedic implants due to polymicrobial infections is one of the leading causes of clinical complexities for long-term metal implantations. The current evaluation of the biocompatibility of an implant material considers microbial resistance as one of the primary parameters. However, external antibiotics interfere with biomaterial assessment and have numerous off-target effects. Therefore, our research comprehensively establishes titanium-copper (Ti-Cu) alloys as intrinsic microbial-resistant biomaterial suitable for implant applications. Furthermore, we incorporated 10%Ta in the Ti-Cu alloys to enhance biocompatibility and mitigate potential Cu toxicity. In vitro, bio-tribological testing of the TiTaCu compositions resulted in comparable performance when considering volumetric wear, adhesive, and cohesive failure. Significantly, the TiTaCu compositions displayed a cathodic shift in open circuit potential under tribological testing. The presentation will discuss alloy design via 3D Printing and the bio-tribological performances of these alloys. |
