Solutions Illustrate execution configuration of this invention makes the re-generation decay with the restoration material and gearwheel system decrease of the gearwheel, the long term anti-bacterial Characteristic which material to the whole restoration of the gearwheel distributes or as the means which are removed,/fungistatic chemical compound is utilized. Further in details, this invention, in order the restoration material of the gearwheel and re-generation decay during gearwheel system it decreases or to remove, or, the metal, the metal oxide and the metal salt, utilizes insoluble fungistatic organicity chemical compound, dissolved fungistatic organicity chemical compound, and organicity metal chemical compound the long term anti-bacterial Characteristic which distributes over the whole of the restoration material of the gearwheel/as a fungistatic chemical compound. < Choice figure > It is not【解決手段】 本発明の例示的な実施形態は、歯の修復材料と歯組織との間の再発性崩壊を減少させる、または除去する手段として、歯の修復材料全体に分散された長期間抗菌性/静菌性化合物を利用する。より具体的には、本発明は、歯の修復材料と歯組織の間の再発性崩壊を減少または除去するために、歯の修復材料の全体にわたって分散された長期間抗菌性/静菌性化合物として、金属、酸化金属および金属塩、不溶性静菌性有機化合物、溶解性静菌性有機化合物、および有機金属化合物を利用する。【選択図】 なし
