Prettau® Anterior is a highly biocompatible zirconia material from Zirkonzahn. Due to its high translucency, it is reportedly ideally suited for use in the anterior tooth region.
Moreover, it is also appropriate for use in the posterior tooth region. Prettau® Anterior can be used for partial and single crowns, inlays, onlays, veneers and bridges (with a maximum of three elements).
According to a test procedure for determining the flexural strength, carried out at the University of Pennsylvania, Prettau® Anterior has been able to achieve a value of 670 MPa. Contrary to glass ceramics, it distinguishes itself not only through higher bending strength, but also through its processing method, since neither water cooling nor diamond drills are required. The material is milled dry and with common zirconia burs.
Prettau® Anterior is also engineered to be highly translucent and esthetic. In combination with the Colour Liquid Prettau® Anterior Aquarell especially developed for this purpose, the ICE Zirkon Malfarben, fully anatomical restorations are now also possible in the anterior tooth region. In this way, the problem of ceramic chipping in the anterior tooth region can be avoided. Prettau® Anterior is a polychrome (multi-colored) material. This means that a Prettau® Anterior restoration can be colored in several colors already before the sintering process. Finally, Prettau® Anterior is sintered at only 1,500° C, reportedly resulting in shorter sintering times.
