A new "metal foam" that has similar elasticity and strength to real bone has been introduces as the new generation of biomedical implants. The issue with current implants is the body rejecting the implant such as titanium. If the implant is stronger or less elastic then the surrounding bone the bone could reject it or die. When a bone or dental implant is place in the body it needs to behave in the same manner as the surrounding bones. If it is too strong the bone it will handle too much of load bearing and the surrounding bone will lose its strength and eventually start to die. This foam has also shown to promote bone growth by having a rough surface the binds with the adjacent bone. This bonds with the hosts bone and increases the strength of the implant.
