A dental remineralizing system, including a functionalized calcium-containing complex having an organic surfactant component mechanochemically attached to a distressed calcium phosphate component and blended with the comestible material. The lateral edges of the separators, superimposed while being conveyed by the conveyance unit, are joined to each other by the first joining units from the front end side of a conveying direction. Then, it is determined whether the harness whose position is decided so as to pass through the set pass position interferes with a mechanical part that is read from a storing unit that stores therein three-dimensional model data on the mechanical part through which the harness passes. The mesh ring is interposed between the inner pipe and the outer pipe in a state that the mesh ring plugs an annular opening part defined between opening edges of the opening holes. The mold may include a fugitive material portion to facilitate removal of the mold when the hybrid structure has a complex shape.
