PFZ

Porcelain-fused-to-zirconia restorations from Blackburn are a high-quality alternative to PFM crowns. They are fabricated with a durable zirconia substructure that has esthetic porcelain layered on top. PFMs provide the strength of PFMs without the common esthetic challenges, such as discoloration or the dark line that can appear along the gingiva. We utilize advanced CAD/CAM technology to ensure they offer extremely precise fit. With zirconia's natural translucency, these crowns are warm and offer lifelike esthetics.

  • Hypoallergenic
  • Biocompatible
  • Improved Esthetics over PFMs
  • Requires Conventional Cementation
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).
