 This paper discusses the advantages of using type titanium alloys with low Young's modulus in biomedical applications. These alloys can be used to inhibit bone atrophy and enhance bone remodeling, as well as provide high static and dynamic strength. Additionally, they offer the ability to adjust their Young's modulus depending on the application, allowing them to be used in both removable implant applications and those requiring varying levels of strength.
