A Zirconia crown is made from a hard ceramic material that is practically indestructible. Because of this, it is particularly used for posterior crowns and multi-unit bridges. Zirconia’s durability makes it particularly useful for those patients with bruxism or a hard bite.
Full-contour zirconia is known for its superior strength and is best suited for patients with a heavy bite, bruxism, or even heavy canine guidance.
Layered zirconia restorations combine both the highest esthetics and the strength and flexibility you need for all posterior and anterior cases. Additionally, extensive laboratory testing has shown the fracture toughness and flexural strength of zirconia are significantly higher than that of alumina or any other all-ceramic materials.
Porcelain fused-to-zirconia (PFZ) involves fabricating a full-contour zirconia crown. A window on the face of the crown is cut out so as not to compromise the strength of the zirconia. Then, an overlay of translucent porcelains is layered and baked on. External stains are applied for characterization with incredible results. PFZ is the ultimate solution to the clinician who desires durability and esthetics!
