Abstract
The present invention provides a solution to the problems with known cements by providing a composition comprising (a) microscopic anhydrous pellets or particles containing the most important components of biological fluids or synthetic biological fluids (SBFs), (b) bioactive glass or other bioactive ceramic particles and (c) an appropriate resin such as, but not limited to, bisphenol-alpha-glycidyl methacrylate (BIS-GMA), to form a bone-forming cement which enhances (accelerates) bone production and bone bonding.
