| Abstract Scope |
Affinity of titanium and its alloys (Ti-s) to bone tissue is called “osseointegration” that means indirect bonding to bone via very thin “electron microscopic-scale” encapsulation by collagen fibers. Although titania formed on Ti-s could be a reason of good osseointegration than other metals, improvement of their osseointegration ability and hemocomatibility are desired from surgeons. Recently, we found two interesting “biocompatible” behaviors of Ti-s induced by simple treatments. One is coating of Ti-s with the hydroxyapatite/collagen bone-like nanocomposite (HAp/Col) that we had invented and reported in 2001. The HAp/Col coating on Ti-s accelerates osseointegration at sub-periosteum 3-times faster than biomimetic hydroxyapatite coating. The other is electric polarization of Ti nanotubes formed on Ti surface improved anti-thrombogenicity than bare and as-annealed Ti nanotubes. |
