Prettau® Zirconia: advantages and alternatives of CADdent®

Prettau® Zirconia is a zirconia - developed by Zirkonzahn® - which is shaded prior to the sintering process with the help of specially provided liquids - also by Zirkonzahn® - in order to obtain highly aesthetic, customized frameworks. This work step is also referred to as infiltrating the color. Since the framework soaks up the paint, you will not come across a white framework during subsequent grinding work - unlike with individualization after the sintering process. 

This material is primarily intended for monolithic crown and bridges in order to master challenges such as lack of space, bruxism or ceramic chipping and still achieve an aesthetic solution. But veneer frameworks can also be made from this material and offer a good basis for ceramic veneers - because you can incorporate the color gradient well into the veneer.
 

Different requirements require different solutions

Initially, Zirkonzahn® offered two different materials - Prettau® Zirkon for the restorations in the posterior region and multi-unit bridges and Prettau® Anterior® for restorations in the anterior region up to a maximum of 3-unit bridges. 
In the meantime, industrially shaded materials are also available (Prettau® 2). Prettau® 2 will soon also be available without a color gradient. The flexural strength of this material is similar to that of the original Prettau® Zirconia, with a higher translucency. In order to obtain the most natural color gradient possible, these frameworks can also be customized before sintering. As with all zirconia frameworks, Prettau® Zirconia can also be customized by shading or ceramic veneering after sintering. 

With Prettau® 3 Dispersive®, there is now a material from Zirkonzahn® that not only has a natural color gradient, but also a gradient in terms of flexural strength and translucency. 

The CADdent® alternatives to Prettau® Zirconia

Prettau® Zirkon was the pioneer, but has long since ceased to be the sole ruler in this field. At CADdent® we offer various materials with which you can achieve a result that is equally or even better. Since we can also offer these materials at an even more affordable price, we have removed Prettau® Zirconia from our range.

Restorations of up to 14 units can be implemented in all three materials. In terms of their properties, they are very similar to Prettau® Zirconia. With these three materials, the color is also infiltrated before sintering.

FAB Zirconia 3D is also a white material that is individualized before sintering. Similar to Prettau® 3 Dispersive®, there is a gradient in translucency and flexural strength. These properties make FAB Zirconia 3D - in addition to its high aesthetics - an extremely antagonist-friendly material.

OUR CONCLUSION

We ourselves have worked with Prettau® Zirconia for a long time and - in addition to small challenges regarding the colour - were basically satisfied with it. During regular material tests, however, we were able to identify materials that are in no way inferior to Prettau® Zirconia in terms of properties and aesthetics and at the same time are offered at a more affordable price.
