Calcium hydroxylapatite (Ca/sub 10/(PO/sub 4/)/sub 6/(OH)/sub 2/, HA) has been recently finding application in clinical practice. Synthetic HA is used in hard tissue replacement application. The technique of making an HA surface coating on ceramic and titanium endoprotheses has been developed. The introduction of HA in dental filling materials allows one to obtain filling physical properties most similar to those of tooth tissues.
