New Prettau® 3 Dispersive® zirconia with Gradual-Triplex-Technology

Zirkonzahn’s Prettau® Dispersive® zirconia materials are already provided with a natural colour gradient during the manufacturing process, thanks to a special technique that does not blend colours into layers but “disperses” them evenly. 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 flexural strength levels change. Whereas 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 final prosthesis with a colour matching with the patient’s natural teeth, a special Prettau® 3 Dispersive® zirconia shade guide is available, with sample teeth in the shape of a premolar as well as upper and lower incisor. 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.
