Prettau® 4 Anterior® is a new and highly biocompatible zirconia material from Zirkonzahn. Due to its high translucency it is ideally suited for use in the anterior tooth region and hence offers an ideal alternative to lithium disilicate. Moreover, it is also perfectly appropriate for use in the posterior tooth region.
RANGE OF APPLICATIONS
Partial and single crowns
Inlays, onlays and veneers
Bridges with max. 3 elements
Extremely translucent zirconia for the elaboration of single crowns, inlays, onlays, veneers and at maximum 3-unit bridges (full contoured or reduced structures for ceramic layering)
Flexural strength of 670 MPa (University of Pennsylvania)
Particularly suited for the anterior tooth region
Ideal alternative to lithium dislicate
Also perfectly appropriate for posterior tooth restorations
Higher translucency due to optimised microstructure of the zirconia
No ceramic chipping and abrasion to the antagonist tooth
Contrary to glass ceramics it distinguishes itself not only through the higher flexural strength, but also through its processing method:
As for Prettau® Zirconia, also for processing of Prettau® 4 Anterior® neither water cooling nor diamond drills are required. The material is milled dry and with common zirconia burs. This results in shorter milling times, lower material consumption and tool wear. The material can be processed with Zirkonzahn Milling Units M1, M1 Wet, M1 Wet Heavy Metal, M4, M5 Heavy and M6 Wet Heavy Metal. No upgrade is necessary.
