• With a very wide range of applications – from partial crowns to full arches – Prettau® is the ideal zirconia for solving common problems such as narrow spaces, bruxism or ceramic chipping, providing patients with functional and aesthetic restorations.
• 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.
