Abstract

Titanium-aluminum-niobium alloys have shown promise for biomedical implant applications in recent years. In particular, it has been shown that their fatigue resistance, wear resistance, and tensile strength are equivalent to or better than that for the commonly used implant material, Ti-6Al-4V. In addition, their elastic modulus is slightly lower that that for Ti-6Al-4V. In vivo studies have shown that the reactivity between Ti-Al-Nb alloy particles and mice calvaria, including osteoclast, T-cell, and bone-deterioration measurements, is statistically more favorable than that for Al2O3 and commercially pure titanium. In this work the cell attachment and adhesion of Ti-15Al-33Nb and Ti-21Al-29Nb is compared to that for Ti-6Al-4V as measured by osteoblast absorption and staining techniques. Overall, the results of this study further support the idea that such Ti-Al-Nb alloys have significant potential for biomedical implant applications.
