Porcelain-Fused-to-Zirconia (PFZ) restorations are formed by porcelain being veneered over zirconium oxide. They have become popular with both dentists and patients as they combine strength, durability and aesthetics.
PFZ has improved aesthetics over monolithic zirconia. High-strength restorations are possible in zirconia in load-bearing areas with veneered porcelain in non-load bearing areas. Avoid use in bruxers or patients with parafunctional activities.
