Hybrid layer - 5Y/3Y multicolored zirconia
Nacera® Pearl Natural zirconia gives all constructions - from single crowns to large fully anatomical implant-supported restorations - a lifelike character, as the natural color gradient and translucency of the teeth are revealed in natural transitions after sintering. 16 shades, two bleach shades according to the VITA® shade guide and a specially developed bleach shade cover all common tooth shades and meet the highest esthetic demands.
Perfectly suitable for:
All indications: from monolithic single crowns to complex superstructures for the anterior and posterior region.
