Abstract

A method of producing a restorative material used to restore a tooth-deficient area in an oral cavity, the method comprising: positioning, in a support carrier, a first cell mass formed from either mesenchymal cells or epithelial cells and a second cell mass formed from the other of the mesenchymal cells or epithelial cells, one of the mesenchymal cells or epithelial cells being derived from a tooth germ and the first and second cell masses being not mixed with each other but made to closely contact each other; culturing the first and second cell masses to form a reconstructed tooth germ or tooth; and confirming directionality of the reconstructed tooth germ or tooth formed by the culturing so as to enable the reconstructed tooth germ or tooth to be embedded in the tooth-deficient area such that a tip of the tooth faces an interior of the oral cavity, the tooth germ or tooth whose directionality has been confirmed being used as a restorative material to obtain an equivalent of a missing tooth in the tooth-deficient area. A method for restoring a tooth-deficient area, the method comprising; embedding the reconstructed tooth germ or tooth obtained by the production method in the tooth-deficient area.
