Our Prettau® Dispersive® zirconia materials are provided with a gentle and natural colour shading already during the manufacturing process thanks to a smooth, dispersive shade transition. With the new Prettau® 3 Dispersive® zirconia, we have now developed a zirconia material with a triple gradient by using the Gradual-Triplex-Technology. In addition to the colouring, also translucency and bending strength levels change. While the incisally increasing translucency results in a highly translucent incisal edge, the cervically increasing flexural strength results in an extremely high flexural strength at the tooth neck. Accordingly, Prettau® 3 Dispersive® can be used for all kinds of zirconia restorations, although it is particularly suitable for monolithic restorations. For a material-identical determination of the patient's tooth colour, special zirconia shade guides with sample teeth made of Prettau® 3 Dispersive® are available in the shape of a premolar as well as lower and upper incisors. If the material of the shade guide and the material of the zirconia crown are identical, it is ensured that the colour of the zirconia restoration corresponds 1:1 with the natural tooth colour of the patient.
