high strength – cubic zirconia system
DD cube ONE® – the first cubic zirconia with unique break protection factor. The multi-indicative ceramic combines translucency and robustness to enable highly aesthetic full contour restorations and more.
Through a newly developed material composition (4Y-TZP) and optimised manufacturing processes, a hybrid micro-structure is set in the ceramic. The crystal structure of DD cube ONE® has a perfect ratio between cubic and tetragonal zirconium oxide particles.
The defined amount and controlled size of the cubic crystals reduce the refraction index and increases the translucency. The dominant, smaller, tetragonal crystals increase the stability.
The perfect balance between mechanical robustness and translucency.
