Hybrid layer – 5Y/3Y multicolored zirconia
Nacera® Pearl Natural is suitable for the fabrication of highly aesthetic restorations with large spans. The different translucencies and flexural strengths from cervical toincisal ensure stability and aesthetics. The hybrid layer from the “blue-cold” aesthetic line has a precise layering and fits perfectly into the row of teeth.
Benefits:
- Highest precision due to distortion-free material
- High process reliability during processing – no indication restrictions due to >800 MPa in the incisal area
- Fast and cost-effective for natural-looking fully anatomical (monolithic) restorations
