Oral Z Ultra
Zirconia core with porcelain overlay. With a flexural strength of up to 1,450 MPa, the zirconia substructure is practically indestructible. Like the Oral Z Lingual, Oral Z Ultra is hypoallergenic and biocompatible. Crafted by layering esthetic porcelain over a zirconia substructure, they provide the strength of PFM crowns while eliminating esthetic challenges, such as discoloration or the dark line that can appear along the gum line. They require conventional cementation and are also a good option for ceramic veneers. Through the use of advanced CAD/CAM technology, they provide consistently accurate fit. Due to zirconia's natural translucency, these crowns are warmer and provide superior lifelike coloration when compared to their PFM counterparts.
