How to maximise the potential of multilayered zirconia

15/7/2020· The use of pre-shaded zirconia with a highly translucent gradient brings more efficiency into the dental laboratory. Owing to the advanced properties of materials like KATANA Zirconia multilayered discs, true-to-life restorations can be created without any, or with only a thin vestibular layer of, veneering porcelain. This saves considerable time in the laboratory.
