Zirconia with Gradual-Triplex Technology: natural colour gradient, extremely high bending strength and highly translucent cutting edge – Available now!

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 for the upper, lower and posterior region. 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.

Properties at a glance

  • Zirconia with Gradual-Triplex Technology: Triple gradient with natural colouring as well as increasing bending strength and translucency values
  • Cervically increasing flexural strength; extremely high flexural strength at the neck of the tooth
  • Incisally increasing translucency; highly translucent incisal edge
  • Merging colour gradient that reproduces the natural tooth colours from dentine to enamel
* Average value of the biaxial bending strength from several test series
  • Colour scheme from A1-D4 as well as 3 Bleach shades; special zirconia shade guides in the shape of a premolar as well as lower and upper incisors (also customisable!)
  • Manual colouring with Colour Liquids is not required anymore, but can be done with Colour Liquid Prettau® Aquarell intensive colours to achieve a more patient-specific result
  • No limitations! Can be used for single crowns, inlays, onlays, veneers, bars and multi-unit bridges (reduced or fully anatomical), especially suitable for monolithic design
  • Fast sintering of single crowns possible
  • No ceramic chipping (thanks to the full anatomical design)
  • Personalisation after sintering with ICE Stains Prettau® and ICE Stains 3D by Enrico Steger

Processing

  • Placing the designed structure in the Zirkonzahn.Nesting software according to the displayed colour gradient
  • CAM-dry processing
  • Sintering (1500 °C); fast sintering of single crowns possible
  • Glazing with 3D Glaze Base, Glaze Plus
  • High gloss polishing
  • Insertion: Cementation or screwing
