摘要： A method for strengthening dental restorative material is disclosed, which comprises depositing one or more inorganic salts of metals selected from rubidium, cesium, and potassium on the surface of a coated material of a dental restorative material obtained by coating and firing a dental porcelain fused to metal material. The dental restorative material is containing leucite and sodium on the surface of a dental alloy substrate, and heat treating the coated material at temperatures of 380.degree. C. or higher but lower than the melting point of the inorganic salt and the strain temperature of the coated material. According to the method of this invention, the coated material can be strengthened with ease while maintaining its translucency and color tone, without using any special device.

摘要： An indicator is useful for detecting pressure points on a denture. The indicator is made of a composition that easily adheres to oral mucosa, has a proper viscosity in an oral cavity environment, can be properly spread between an oral mucosa surface and a denture base, and easily specifies an affected part. The composition includes a fatty acid ester having a melting point of 30 to 50° C., a water-soluble high polymer, and a metal oxide. Preferably, the fatty acid is 40 to 95% by weight of the composition, the water-soluble high polymer is 1 to 59% by weight of the composition, and the metal oxide is 0.1 to 50% by weight of the composition.
