-          Prettau^® 2 and Prettau^® 2 Dispersive^® are highly translucent zirconia typologies with excellent flexural strength. Furthermore, their outstanding aesthetic properties allow the design of monolithic restorations, preventing the risk of ceramic chipping. With Prettau^® 2 and Prettau^® 2 Dispersive^®, it is therefore possible to provide patients with biocompatible, individual and highly stable dental restorations, from single crowns to full arches. Compared to Prettau^® 2, the Dispersive^® typology is already provided with a slight natural colour gradient during the production process.

-          With the new Prettau^® 3 Dispersive^® zirconia, the concept of Gradual-Triplex-Technology was introduced: in addition to the colouring, also translucency and flexural strength levels change. In this way, while the incisally increasing translucency results in a highly translucent incisal edge, the cervically increasing flexural strength leads to an extremely high flexural strength at the tooth neck. Prettau^® 3 Dispersive^® is particularly suitable for monolithically designed restorations and can be used for the fabrication of single crowns up to bar-supported multi-unit bridges.

-          Prettau^® 4 Anterior^® and Prettau^® 4 Anterior^® Dispersive^® have been specially designed for the anterior region and are therefore characterised by a particularly high translucency. However, both materials are also perfectly suited for the posterior region. The Dispersive^® version features a natural colour gradient evenly distributed throughout the material for a dispersive effect. These two types of zirconia are suitable for the production of single crowns, inlays, onlays, veneers and three-unit bridges.

For a final result which matches with the colour of the patient's natural teeth, special shade guides were developed: Zirkonzahn Shade Guides are composed of monolithic zirconia sample teeth in the shape of premolars, upper and lower incisors, and they are available in Prettau® 2 Dispersive®, Prettau® 3 Dispersive® and Prettau® 4 Anterior® Dispersive® zirconia.
