Problems solved by technology

However, in the case of a bone filling material using hydroxyapatite, although bone is formed by osteoblasts, the bone filling material cannot be absorbed by osteoclasts, so it cannot be replaced by bone

Embodiment 1

[0100] In this example, a porous body containing calcium carbonate and a porous body containing carbonate apatite were manufactured.

[0101] First, a porous body containing calcium carbonate was manufactured in accordance with the following procedure.

[0102] Add and mix 74 parts by weight of calcium hydroxide powder and 6 parts by weight of polyethyleneimine, which is an organic substance that can be cured by a chemical reaction, in 80 parts by weight of distilled water as a solvent to prepare a slurry (slurry preparation process) .

[0103] Then, 1 part by weight of polyoxyethylene lauryl ether and 1 part by weight of triethanolamine sulfate were added and mixed as a foaming agent to the obtained slurry.

[0104] Then, air bubbles were introduced using a hand mixer to the slurry to which the foaming agent was added and mixed to form a foamed slurry (bubble introduction step).

[0105] Inject the foam state slurry into a mold made of polyethylene of 10 cm × 10 cm × 5 cm, ...

Abstract

Provided is a method for producing a porous body that includes calcium carbonate, the method including a digesting and carbonizing step in which digestion and carbonization of a porous body that includes calcium oxide is performed in the presence of water and under a stream of a carbon dioxide-containing gas.

Description

technical field [0001] The present invention relates to a method for producing a calcium carbonate-containing porous body and a method for producing a carbonate-apatite-containing porous body. Background technique [0002] Conventionally, bone filling materials have been used for reconstruction or regeneration of bone defects caused by trauma, etc., or for increasing the thickness of the jawbone during implantation treatment. [0003] Hydroxyapatite and the like have been studied as materials for bone filling materials. [0004] The bone filling material using hydroxyapatite has osteoconductivity, that is, when it fills a bone defect, it activates the bone-forming cells existing in the mother floor bone to generate new bone tissue, and fills in the bone. The ability of a material's surface to form bone. [0005] Therefore, the bone filling material is required not only to have the above-mentioned osteoconductivity but also to be replaced by bone as its characteristic. How...
