Titanium implants are mechanically strong and osseointegrate well in many patients, but they are biologically inert at the interface. In a meaningful subset of cases, aseptic loosening and fibrous encapsulation still cause failure. Plasma-sprayed hydroxyapatite is already used clinically, but the high-temperature process and rapid cooling cause instability in vivo. At the other extreme, hydroxyapatite sintered at high temperature is highly crystalline but brittle, and osteoclasts can barely resorb it, so it can persist in the defect for years and resist remodeling 1.Hugoen
