PEARL

 

Highly translucent zirconium oxide for natural-looking.

Available in white and in several colored shades, it provides the ideal basis for dental aesthetics. The blanks, each industrially manufactured in Germany using modern equipment, can be processed in most available milling machines and are characterized by their consistent color results and excellent machinability. Finished with a stain-and-glazing technique or using minimal stratification by Cut-Back, Nacera® Pearl is always a reliable quality foundation for monolithic crowns and bridges, as well as abutments and screw retained restorations. Furthermore, the shaded  blanks speed up the production process considerably, because manual shading by dipping is no longer necessary. Thereby the reliability of colors and production processes increases, eliminating even the danger of white spots during grinding.


Flexural Strength

4-point bending strength (MPa) DIN EN ISO 6872. The higher the fl exural strength of zirconia (ZrO2) the better the stability under masticatory loading.

Flexural Strength

Translucency

The higher the translucency the more permeable the material is to light. (Less Opacity)Translucency
