PROBLEM TO BE SOLVED: To obtain the subject material which is useful as an economical inhibitor of various saprophytes propagation inhibitor which can safely inhibit the saprophyte propagation with energy saved and is useful as a biomaterial by pressing a specific shape of titanium oxide and a specific shape of hydroxyapatite into the base plate. SOLUTION: This saprophytes propagation inhibitor is prepared by pressing spheres of titanium oxide or spheres coated with titanium oxide into the base plate. The infestation-inhibiting composite material and the biomaterial are prepared by pressing titanium oxide spheres, spheres coated with titanium oxide and/or hydroxyapatite, TCP or calcium phosphate spheres into the base plate. In addition, two or more kinds of spheres of titanium oxide, hydroxyapatite, TCP, calcium phosphate, and antiinflammatory agents are preferably pressed in the base plate. The propagation inhibitor is useful for the prevention of propagation of saprophytes in water tanks and the like, while the composite material is useful as a biomaterial for artificial tooth crown, dental roots, artificial bone and the like. |
