Studies Of Casting Properties Of Low Modulus Ti-24Nb-4Zr-7.9Sn Alloy For Dental Application

Titanium and its alloy started gaining wide spread usage as implant materials in the early 1970s.Although commercially pure(C.P.)titanium offered better corrosion resistance and tissue tolerance than stainless steel comparatively lower strength and unfavorable wear properties restricted its usage to certain applications. Interest in the Ti-6Al-4V ELI alloy for total joint prostheses grew significantly in the United States toward the late 1970s because of its high strength, low elastic modulus, excellent corrosion resistance, and good tissue tolerance. While there have not been any clinically substantiated reports of problems stemming from the presence of the elements aluminum and vanadium in current titanium alloys, there are reported concerns based on potential toxicity, potential inhibition of apatite formation, and possible association with neurological disorders. Studies have aroused significant interest in producing materials with a low modulus of elasticity for the next generation of implant materials. The preferred titanium alloy for orthopaedic applications should have low modulus of...
