PFZ

High Precision Dental Laboratory offers highly esthetic porcelain-fused-to-zirconia restorations, which are an all-ceramic alternative to porcelain-fused-to-metal crowns. Our skilled team of craftsmen skillfully layer esthetic porcelain on top of a zirconia substructure. PFZs match the strength of PFM crowns without risking the common esthetic challenges, such as discoloration or the dark line that can appear along the gingiva. Our digitally innovative team uses the most advanced CAD/CAM technology to ensure every PFZ crown provides consistently accurate fit. Due to zirconia's natural translucency, these crowns are warmer and provide superior lifelike coloration when compared to their PFM counterparts.

Features:

  • Hypoallergenic
  • Biocompatible
  • Lifelike Esthetics
PFZ

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).
