The porcelain-fused-to-zirconia restorations from Lintec Dental Labs™ offer unparalleled esthetics for the anterior. Fabricated by layering esthetic porcelain on top of a durable zirconia substructure, this restoration benefits from high flexural strength and translucency. Unlike porcelain-fused-to-metal restorations, PFZs do not suffer from common esthetic disadvantages like discoloration or graying along the gingiva line. Due to zirconia's natural translucency, these crowns offer a warmer, lifelike coloration that will perfectly complement and blend in with your patient's preexisting dentition.

The ideal preparation for PFZs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.
- Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
- Maxcem Elite (Kerr)
- Panavia F 2.0 (Kuraray) - ideal for short, tapered preparations
- Glass ionomer cement (GC Fuji, GC America)
If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).
