PURPOSE:To form a hard structure even in the case being transplanted to a part with soft structure or at a boundary zone, without risk of impairing its excellent structural affinity, by allowing ceramics of calcium phosphorate series to contain a suspension of calcium hydroxide or magnesium oxide. CONSTITUTION:A hard structure forming material contains ceramics of calcium phosphorate series and a suspension of calcium hydroxide or magnesium oxide. Preferable examples of the ceramics of calcium phosphorate series are calcium phosphorate, hydroxyapatite, and fluoric apatite, the secondly named is the most favorable from the viewpoint of adaptability to a living body. Because the main body of such a composite is ceramics of calcium phosphorate series, its structural affinity is excellent, and the usage is simple, and various materials can be mixed. Because having such an induction ability as showing formation of a hard structure even in the sub-skin bond structure, it exhibits excellent hard structure formation to provide excellent effect at such a treatment as filling a missing part in a bone and filling a root tube. |
