PFZ

YDL Concert’s porcelain-fused-to-zirconia crowns exhibit the esthetics of porcelain, while ensuring lasting durability with a zirconia substructure. With a flexural strength of up to 1,450 MPa, our PFZ crowns are made to last. Our PFZ restorations are biocompatible and hypoallergenic. Porcelain-fused-to-zirconia also eliminates common esthetic disadvantages of PFM restorations, including discoloration and a dark line appearing along the gingiva.

Product Tiers
  • Our Porcelain-Fused-to-Zirconia restorations are available in our Premium, Premium +, and Master product tiers

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

Preparation

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)

Tech 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).
