Multilayer – 5Y multicolored zirconia
DD cubeX ²® ML is suitable for highly aesthetic restorations up to three sections. The high light transmission through the increased Proportion of the cubic phase in the cubic-tetragonal mixed structure and the stable mechanical properties are perfectly balanced. The integrated color gradient enables the efficient production of Restorations with a natural appearance.
Advantages
- More stable than lithium disilicate with comparable aesthetics
- Our favorite for the front teeth area
- Incisal and dentin layer + 2 transition layers = natural color gradient
- Aesthetic finish with minimal effort
