Abstract
The present invention relates to an apatite composition comprising 0.001-99.999 wt. % of an apatite and 0.001-99.999 wt. % of a glass carbomer, based on the total weight of the apatite composition. The apatite is preferably a fluoroapatite according to the general formula (I): wherein: M is a cation other than Ca2+, B is an anion other than P043″, A is F″, 0≦x≦9, 0≦y≦5, and 0≦z≦2, and most preferably Ca10(PO4)6F2. The apatite composition is advantageously used as a dental filling material, a denting bonding cement, a bone cement, a bone replacing material, in dental care and cleansing products, glass-ceramics, bone scaffolds and bone substrates, and as a coating material for crowns and bridges.
