摘要： PURPOSE:To enhance workability and compression strength and to facilitate the unification with the bone tissue or teeth tissue of a living body, by compounding alkali metal salt or ammonium salt of citric acid with at least one of an alpha-tricalcium phosphate powder and a curing liquid. CONSTITUTION:This curable composition is composed of an alpha-tricalcium phosphate powder or a powder agent consisting of said powder and a barium sulfate powder and a curing liquid, and alkali metal salt or ammonium salt of citric acid is compounded with at least one of the aforementioned powder agent and the aforementioned curing liquid. The use amount of barium sulfate is 5-30wt.%, pref. 10-20wt.% of the alpha-tricalcium phosphate in order to improve not only X-ray imaging property but also kneading workability. As the curing liquid, especially, an aqueous solution of a homopolymer or copolymer of unsaturated carboxylic acid, an aqueous citric acid solution or a solution mixture thereof can be pref. used because excellent compression strength is imparted to a cured substance. The concn. of the aqueous solution is pref. within a range of 10-60wt.%.

摘要： PURPOSE:To provide the titled composition composed of alpha-tricalcium phosphate powder, barium sulfate powder and an aqueous solution of citric acid, effective in promoting the generation of newly grown bone or tooth when applied to defective part of cavity of bone or tooth and capable of gradually integrating with the tissue of bone or tooth of the body. CONSTITUTION:The titled composition is composed of (A) alpha-tricalcium phosphate powder, (B) 5-30wt% (preferably 10-20wt%) barium sulfate powder based on the component A and (C) an aqueous solution of citric acid having a concentration of >=30wt% (preferably 35-55wt%). The composition has excellent biocompatibility, good workability, high compression strength and improved X-ray contrasting property. The weight ratio (powder/liquid ratio) of the mixture of the components A and B to the component C (A+B/C) is 1.3-3.

摘要： PURPOSE:To improve kneading workability and to facilitate the unification with the bone tissue or teeth tissue of a living body, by compounding alkali metal salt or ammonium salt of citric acid with at least one of a powder agent, which consists of an alpha-tricalcium phosphate and a calcium hydroxide powder, and a curing liquid. CONSTITUTION:This curable composition consists of a powder agent, wherein an alpha-tricalcium phosphate powder and a calcium hydroxide powder are together used and a calcium oxide powder or, if necessary, a barium sulfate powder is further used, and a curing liquid, and alkali metal salt or ammonium salt of citric acid is compounded with at least one of the aforementioned powder agent and the curing liquid. The proper use amount of the calcium hydroxide or calcium oxide powder is 0.5-5wt.% of the alpha-tricalcium phosphate powder and the use amount of the barium sulfate powder is used within a range of 5-30wt.% of the alpha-tricalcium phosphate. The curing liquid is composed of a copolymer consisting of polyacrylic acid or acrylic acid and at least one of unsaturated carboxylic acid selected from a group consisting of methacrylic acid, maleic acid, fumaric acid and itaconic acid and the concn. of the aqueous solution of said copolymer is pred. within a range of 10-60wt.%.

摘要： PURPOSE:To increase a bone growth speed after filling, by compounding a specific amount of a calcium hydroxide or calcium oxide powder with an alpha- tricalcium phosphate powder. CONSTITUTION:A calcium hydroxide or calcium oxide powder is compounded with an alpha-tricalcium phosphate powder in an amount of 50% or less by wt. of the latter or in an amount of 80 equivalent % or more based on the sum of the number of the acid equivalents of a curing liquid. When the compound ratio of the calcium hydroxide or calcium oxide powder to the alpha-tricalcium phosphate powder exceeds 50wt.%, a kneaded mixture having flowability is not obtained when the powder agent is kneaded with the curing liquid and the filling workability to the omitted part or gap part of a bone or tooth becomes inferior. When said compounding ratio is below 80 equivalent % based on the sum of the number of the acid equivalents of the curing liquid, it is unpref. since calcium hydroxide or calcium oxide generates the neutralizing reaction with the curing liquid to be lost from a cured substance and the stimulation for forming secondary hard tissue lowers.
