Description
Nacera® Pearl blanks are available in seven dyed colour nuances. Highly translucent zirconium dioxide homogeneously shaded in all 16 vita classic colors and two bleach-colors.
Nacera® Pearl shaded is a German premium-product made of translucent zirconium dioxide, that guarantees natural-looking restorations. The combination of extreme flexural strength (1400 MPa) and high translucency allows a multiple-indicative use and meets the restorative requirements in dental CAD/CAM processes.
Nacera® Pearl shaded is not only frequently used for monolithic full contour restorations, but it also provides a reliable basis for substructures in the layering technique. Our shaded blanks speed up the production considerably while simultaneously increasing the aesthetic quality of the results.
Benefits & Indication: The 16 Vita classical colors and the two bleach-shades can be reached easily and selectively; Multiple indication – extreme flexural strength paired with high translucency for all requirements; Shaded blanks increase the reliability of production processes and colors, thereby eliminating the danger of white spots during regrinding; Economical, as no dipping or drying necessary; Excellent Machine-ability: Thin margins can be milled without having to worry about chipping or cracks. Lifetime of milling burs increases up to 15 %; Natural aesthetic for monolithic restoration; Flexural strength 1400 MPa (biaxial)
