DD Bio ZA Zirkonoxid

These blanks are distinguished by their enhanced strength and long-term hydrothermal stability. An absolutely homogenous structure is achieved through a specially developed production process. The blanks are optimised for rapid milling strategies and provide excellent edge stability and green body breaking strength during processing.

The blanks are optimised for Amann Girrbach Ceramill Motionâ*system. All blanks consist of pre-sintered zirconium dioxide stabilised with yttrium oxide (3Y-TZP-A).
