Being production manner of the restoration material which is used in order to restore the gearwheel deficiency section inside the buccal cavity, making fit in each case either the mesenchyme type cell and the epithelium type cell which one side are the gearwheel embryo-derived the 1st cell aggregate which consists of one side respectively or without mixing the 2nd cell aggregate, laying out inside the support substrate, it cultured, inside the buccal cavity doing thing, the gearwheel embryo or the Tip of the gearwheel make the gearwheel embryo or the gearwheel form which was reconstructed, in order to be able embedding in the aforementioned deficiency section, it was formed by aforementioned culture the gearwheel embryo or the directivity of the gearwheel which was reconstructedVerifying, it included, as for the aforementioned gearwheel embryo or the gearwheel where directivity was verified, in particular production manner and the aforementioned gearwheel deficiency section which are used is done as the restoration material in order to obtain equivalent ones of the gearwheel which in the aforementioned gearwheel deficiency section, deficiency, the aforementioned it is obtained by this production manner embedding the gearwheel embryo or the gearwheel which was reconstructed, restoration manner of the gearwheel deficiency section which is included.口腔内の歯欠損部を修復するために用いられる修復材料の製造方法であって、いずれか一方が歯胚由来である間葉系細胞と上皮系細胞とのいずれか一方でそれぞれ構成された第1の細胞集合体及び第2の細胞集合体を、混合することなく密着させて支持担体内部に配置して培養し、再構成された歯胚又は歯を形成させること、歯胚又は歯の先端部を口腔内側して前記欠損部に埋設し得るように、前記培養によって形成された再構成された歯胚又は歯の方向性を確認すること、を含み、方向性が確認された前記歯胚又は歯は、前記歯欠損部において、欠損した歯の等価物を得るための修復材料として用いられる当該製造方法と、前記歯欠損部に、この製造方法により得られた前記再構成された歯胚又は歯を埋設すること、を含む歯欠損部の修復方法。
