Prettau®, the zirconia from the Dolomites for the patients you value

Inspired by the base properties of zirconia, MDT Enrico Steger founded his Zirkonzahn company in 2003 with the aim of getting the best out of this dental material. In the heart of the Alps, Zirkonzahn’s team constantly works to imbue zirconia with unique properties, to infuse it with luminosity and extraordinary attributes. The result is a special material: Prettau® zirconia. A material conceived, produced and tested without compromise, to ensure the best quality.


Prettau Bridges (monolithic, 14-unit bridges made with Prettau) have been used for more than 15 years to provide patients with aesthetic and long-lasting restorations. Starting from classic Prettau zirconia (1200 MPa), the range has been expanded over the years with new materials, to meet dentists’ and patients’ requests. Prettau 4 Anterior (670 MPa), with its extremely high translucency, is the ideal alternative to lithium disilicate. Prettau 2, on the other hand, combines its high flexural strength (1300 MPa) with excellent translucency, becoming the optimal solution for particularly aesthetic full-arch bridges, both monolithic and reduced.

With the Dispersive® line, the path of monolithic design has been brought a step forward: indeed, Dispersive materials are characterised already during the manufacturing process by a natural colour gradient thanks to a special technique that does not blend colours into layers but disperses them evenly. The latest innovation within Zirkonzahn’s range of zirconia materials is Prettau 3 Dispersive. The material is already provided with a triple gradient of natural colour, flexural strength and translucency. Therefore, it is particularly suitable for the production of monolithic natural-looking restorations:

  • Zirconia with Gradual-Triplex-Technology: triple gradient with natural colour as well as increasing flexural strength and translucency values:
    • Cervically increasing flexural strength; extremely high flexural strength at the tooth neck;
    • Incisally increasing translucency; highly translucent incisal edge; and
    • Colour gradient which reproduces the natural tooth colours from dentine to enamel.
  • Colour scheme from A1-D4 as well as 3 bleach shades; special zirconia shade guides in the shape of premolar as well as lower and upper incisors (also customisable!);
  • Manual colouring and further characterisation is no longer required, but can be performed to achieve more patient-specific results; and
  • Especially suitable for monolithic design, which avoids ceramic chipping.
