Prettau® 3 Dispersive® - Zirconia with triple gradient 

 
 
 
 

*

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 in the shape of a premolar as well as lower and upper incisors. Only if the material of the shade guide and the material of the zirconia structure are identical is it possible to achieve a restoration colour as close as possible to the patient’s natural teeth.

 

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
  • 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
