DD Bio Z – High Strength (HS)
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 balanced composition and fine grain structure ensure excellent technical properties.
- highest flexural strength
- high aging resistance
- homogenous density
- excellent fitting
- best coloring results with our DD Shade Concept® Liquids
