HILDEN, Germany: By providing a natural colour gradient and high translucency, the modern multilayered zirconia KATANA Zirconia STML (Kuraray Noritake Dental) meets high aesthetic demands in restorative dental procedures. Clinicians who wish to achieve further characterisation and optical adjustment to the adjacent teeth have two options: veneering with feldspathic ceramic or glazing and individualisation with ceramic stains.
