Doceram, Nacera® Pearl Multi-Shade of highly translucent zirconium dioxide. A New ergonomic multi-layered system.
After sintering, Multi-Shade blanks replicate the smooth transition of colors you can observe in real teeth, thereby full contour as well as substructures constructions with a natural appearance.
To achieve most common tooth colors, Nacera® Pearl Multi-Shade blanks are available in the Vita shades A, B, C, and D. Their application is quite simple: Depending on the height positioning, for example, the colors A3, A2 or A1 can be attained in an A-blank. The same is true for the other shades. The structural height of 18 mm ensures that sufficient space for vertical
shifting is available. Thus, you receive an efficient and ergonomic multi-layered system, which covers almost all Vita classic shades with only four different blanks. Finished with a stain-and-glazing technique or using minimal stratification
by Cut-Back, Nacera® Pearl is always a reliable quality foundation formonolithic constructions, that meet the highest requirements for natural aesthetics.
Advantages: Highly translucent multi-layered system; Natural and smooth transitions from cervical to incisal; Extremely efficient: one blank covers three shades; Quick and economical for natural-looking monolithic restorations; Flexural strength (biaxial): 1400 MPa; Excellent Machinability: Thin margins can be milled without having to worry about chipping or cracks; Lifetime of milling burs increases up to 15 %
