Processing 


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 and M5 Heavy. No upgrade is necessary.
