Rapid-hardening calcium phosphate cement compositions

摘要

A bone or dental implant material in the form of a paste includes a mixture of calcium phosphate and/or calcium-containing powders and salt solutions with a cationic component other than calcium and an anionic component that forms strong calcium complexes in the solution, or is insoluble with calcium. The paste is stable, resistant to washout and will form hydroxyapatite and harden relatively rapidly to a cement.
