Abstract

Ti-6Al-4V alloy is mostly used for dental and hard tissue implants, due to its high strength to weight ratio, high corrosion resistance, and relatively low elastic modulus. However, apart from health concerns of V ions release and higher Young’s modulus (~120 GPa) than human bone (~30 GPa), recent research indicates day-to-day cyclic loading instead of a single-load event such as a fall, might be the consequence of inherent stiffness of fixation implants. In this study, Ti-6Mo-4Zr-xSn (at.%) alloy with pliable quality was developed and fabricated to efficiently avoid the potential hazards of fragility fracture and spinal spurs that pinch the spinal cord or its nerve roots and can cause weakness or numbness in the arms or legs—has been a long-term clinical quest. The evidence of its bone matching modulus, pliable mechanical behavior, excellent wear, corrosion and cytotoxicity properties are desirable potentials for future clinical therapy.
