Prettau® 4 Anterior® Dispersive® is a polychromatic and highly translucent zirconia material with a merging colour gradient for the manufacture of single crowns, inlays, onlays, veneers up to 3-unit bridges. The new material can be used both for fully anatomical structures as well as for reduced structures with subsequent ceramic layering.
Prettau® 4 Anterior® Dispersive® does not cause ceramic chipping nor abrasion to the antagonist. Due to its excellent aesthetic properties and high translucency, the material is specially designed for the anterior region, but thanks to its high flexural strength of approx. 600 MPa it can also be used for the fabrication of posterior teeth without any issues. For Prettau® 4 Anterior® Dispersive® processing, neither water cooling nor diamond burs are necessary, which makes the material an ideal alternative to lithium disilicate.
The natural colour transition reproduces the natural tooth colours from dentine to enamel, manual colouring of the restoration before sintering is not required anymore. To achieve an even more patient-specific result, the restoration can still be characterised manually if desired. After sintering, the restoration can be personalised with ICE Zirkon Stains Prettau® and ICE Zirkon 3D Stains by Enrico Steger.
OVERVIEW OF THE CHARACTERISTICS:
Polychromatic pre-coloured zirconia with a merging and natural gradient
For the manufacture of single crowns, inlays, onlays, veneers as well as 3-unit bridges (full contour restorations or reduced structures for ceramic layering)
Particularly suitable for the anterior region, but it can also be used in the posterior region
