PFZ (Porcelain Fused to Zirconia)

PFZ (Porcelain Fused to Zirconia),

Metal Free

Porcelain fused to zirconia provides the best of both worlds.  Porcelain's translucency and characteristics without the worry of dark metal showing through near the margins.

Details

ADA Codes
  • D2740 crown – porcelain/ceramic substrate

  • D6740 crown – porcelain/ceramic (bridge units)
Features
  • Hypoallergenic
  • Biocompatible
  • Improved Esthetics over PFMs
  • Requires Conventional Cementation
Indications

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.

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

The ideal preparation for PFZs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.

Cementation
  • 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)
Notes

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).
