5 Jul 16 - Excel Dental Lab introduced the brand new Color Liquids Prettau^® Aquarell from Zirkonzahn. These water-based, acid-free colors are used to apply on full-contour zirconia structure. Individual custom coloring of finer details such as mamelons, incisal translucency, cervical or interproximal areas is considerably easier and can be performed with pinpoint precision. The final restoration looks exceptionally aesthetic and natural in the desired tooth color.
