PROBLEM TO BE SOLVED: To provide a pure gold-plated denture that makes use of the properties of pure gold, has good wearing feeling, enables tightly chewing and does not become a bad smell source even if used for a long term, and provide a production method for making it.SOLUTION: A pure gold plating 5 is applied as backing processing of a tongued place such as gums of a denture base, the hard palate and the sublingual mucosa. The thickness of the pure gold plating 5 is made 15-50 μm, and thereby the usage amount of precious metal is reduced and the price is lower than the denture using a conventional pure gold. The pure gold plating method, a making method of the denture base and a mounting method of an artificial tooth are combined, and a preferred pure gold denture can be made efficiently.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】純金の持つ特性を生かし、装着感が良く、しっかり噛めて、長期間使用しても悪臭源にならない純金メッキ義歯とそれを製作する製造法を提供する。【解決手段】義歯床の歯肉や硬口蓋や舌下の粘膜など舌が当たる個所の裏装処理として純金メッキ5を施すもので、純金メッキ5の厚さを15~50μmにすることによって貴金属の使用量を低減し、従来の純金を使用する義歯よりも価格を安くする。純金メッキ法、義歯床の製作法、人工歯の取付法を組み合せて、好ましい純金義歯を効率よく製造できる。【選択図】図1
