Zirconia
Layered
Layered Zirconia is 100% metal-free, a feature that prevents gingival darkening and removes the possibility of exposing metallic margins if gum recession begins. Layered Zirconia exhibits the most natural looking of all restorations as it utilizes porcelain glass to mimic the nuances of natural teeth. For multi unit bridges that extend beyond 3 units and still require a high degree of natural vitality, Layered Zirconia is the ideal choice.
