Prettau Zirconia is used to realize all kind of restorations. Zirconia is the result of a chemical process: the basis is Zirconia sand, partially stabilized with Yttrium, and made into Zirconia blanks through a mechanical process. Zirconia dioxide is, among the today available dental ceramics, without any doubt the material with the highest stability and fracture toughness.
Zirkonzahn offers, thanks to an optimized microstructure of the Zirconia dioxide, extra translucent Prettau Zirconia. In combination with Prettau Colour Liquids and the stains you can create full Zirconia bridges, eliminating ceramic chipping.
- Higher translucency thanks to the Zirconia‘s optimized microstructure
- No ceramic chipping
- No abrasion vis-à-vis the antagonist tooth
- 200% higher flexural strength thanks to the eliminiation of the veneer ceramics
- Ideal especially in case of implants, reduced available space or restoration with gingival reconstruction
Why use Prettau® Zirconia?
A reoccurring issue in our professional circles is the question whether solid, full-contour Zirconia crowns are at all indicated in the view of aesthetics, abrasion characteristics, compatibility and strength. Can we recommend them to our patients? As far as (full-anatomical-contour) solid Zirconia restorations are concerned, we all agree that a special translucent Zirconia material is needed first. For this reason we have developed the highly translucent Prettau Zirconia which is used in conjunction with a specialized colouring technique that eliminates the use of veneer ceramics entirely. In this way, aesthetically pleasing full-Zirconia (FZ) restorations, i.e. the ‘Prettau Bridge’ can be realized.
Prettau Zirconia comes into a world of its own especially in the field of implant dentistry, in cases of limited available space or restorations with tissue flanges. One of the many advantages is the complete elimination of posterior occlusal chipping because only the labial or buccal surfaces are porcelain veneered; all functional areas are maintained as solid Prettau Zirconia.
