Our PFZ crowns and bridges are an excellent alternative to PFM crowns. They are practically indestructible because of their high flexural strength of up to 1,450 MPa. They are also hypoallergenic and biocompatible. Crafted by layering porcelain over a zirconia substructure, they provide the durability of PFM crowns while reducing esthetic challenges, such as discoloration or the dark line that can appear along the gingiva. They require conventional cementation and are also a good option for ceramic veneers. Through the use of advanced CAD/CAM technology, they provide a consistently accurate fit. Due to zirconia's natural translucency, these crowns are warmer and provide excellent lifelike coloration when contrasted to their PFM counterparts.

Additonal Information


A CAD/CAM substitute for traditional PFM, our porcelain-fused-to-zirconia can be used for anterior and posterior crowns, crowns over implants, and bridges of up to fourteen units.

  • Attachment cases
  • Cases with less than 1 mm clearance
  • Bruxism
  • Patients who have broken a PFM crown
  • Cases that require bonding

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).

  • D2740 Crown - porcelain / ceramic substrate

Global Laboratories provides exceptional restorations with lifelike esthetics through the combination of scientific expertise and artistic craftsmanship.
