Nacera® Pearl Multi-Shade
The ergonomic system for natural-looking restorations.
We offer a new version of our best material: Nacera® Pearl Multi-Shade zircon oxide. 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 for monolithic constructions, that meet the highest requirements for natural esthetics.
