Isn't that a unique property of titanium and part of why it's chosen for skeletal implants?
When a buddy got a damaged tooth replaced with an implant, he showed me medical scans of the titanium rod in-situ with the surrounding bone highlighted as growing into the rod as if they had an affinity for one another. It was part of a document explaining the safety and why titanium was chosen, how the body doesn't reject the material as foreign etc.
