Bio Pontostar - Au 86.7%
High-gold-content, extra-hard alloy for standard metal-ceramic restorations
High-gold alloy with a high gold and platinum content – for optimal processing.
Rich yellow colour – for restorations which are at once aesthetic and high-quality.
Contains no copper or palladium – extremely corrosion-resistant.
medium grain size 20 µm – high corrosion resistance.
Light-coloured oxide – for greater reliability in aesthetic ceramic veneering.
Biocompatible and corrosion-resistant.
