Why is titanium used for body implants?

Corrosion resistance of the currently used 316L stainless steel, cobalt-chromium, and titanium-based implant alloys relies on their passivation by a thin surface layer of oxide. Stainless steel is the least corrosion resistant, and it is used for temporary implants only. read more

There are a few reasons why titanium is often used for implants. It is harder, yet lighter weight than some steel. It is bacteria resistant. It can be used in conjunction with instruments emitting radiation, and it is incredibly durable and long lasting. read more

One can find titanium in neurosurgery, bone conduction hearing aids, false eye implants, spinal fusion cages, pacemakers, toe implants, and shoulder/elbow/hip/knee replacements along with many more. The main reason why titanium is often used in the body is due to titanium's biocompatibility and, with surface modifications, bioactive surface. read more

This type of implants is known as an osseointegrated implant, and these have become the mainstream implant type. Osseointegration Titanium is commonly used as an implant material as it has high biocompatibility and bonding ability with the bone. read more
