Keramit Bio 998

KERAMIT BIO 998 was developed to fulfil esthetical requirements. This alloy, made almost exclusively of gold (with traces of silver, zinc, indium and manganese) is compatible with most ceramics present on the market. The intense yellow colour, like pure gold, makes it ideal for anterior restorations.

KERAMIT BIO 998 is ideal for inlays with or without ceramic (Elongation %: 35-30%). Its physical and mechanical characteristics allow to use it for inlays and single crowns.
