本発明に基づき構成された合金は、練和後又はアマルガム充填物を窩内に固定し た後に口腔内環境の影響を含む化学的及び／又は電気化学的処理によシ、充填物 の表面の金属的特性が明るい、非金属性の、歯質の色に調和する外観の方向に変 化するように着色することができる。The alloy constructed according to the present invention can be used after kneading or after fixing the amalgam filling in the cavity. After that, the fillings are removed by chemical and/or electrochemical treatment, including the influence of the oral environment. The metallic properties of the surface change towards a bright, non-metallic, appearance that matches the color of the tooth structure. It can be colored to make it look different.
歯科医用アマルガムは従来歯の保存療法にお、いてその効果が認められて来た。Dental amalgam has long been recognized for its effectiveness in tooth conservative treatment.
アマルガム充填物の金属性の光沢外観をそれを取シ囲む歯質の色に調和させる試 みは未だ成功することな（残ったままである。従って本発明の課題は、金属性外 観を特殊な処理によシ、歯質の明るい非金属性外観の方向に変化させることがで きる、歯科医用アマルガムを製造するだめの合金粉末又は合金粉末混合物を提供 することであった。An attempt to match the shiny metallic appearance of amalgam fillings to the color of the surrounding tooth structure. However, the problem of the present invention is to Through special treatment, the appearance of the tooth can be changed towards a bright, non-metallic appearance. Provides alloy powders or alloy powder mixtures for manufacturing dental amalgams. It was to do.
