IPS Emax thumbnail Simply Z Layered


United Dental Lab’s porcelain-fused-to-zirconia restorations are available as our high-quality Simply Z – Layered solution. Simply Z – Layered combines the translucent esthetics of porcelain with the exceptional strength of zirconia for a long-lasting anterior solution. This PFZ is highly customizable and is available either with fully-layered porcelain or with a micro cutback on the facial surface. The practically indestructible zirconia substructure has a high flexural strength of up to 1,450 MPa. These restorations are hypoallergenic and biocompatible. It is a preferable alternative to PFM restorations due to its high esthetics and elimination of common esthetic challenges that are typical of metal-based products. These issues include discoloration and a dark line that appears along the gingiva. These crowns have a warmer, lifelike coloration when compared to their PFM counterparts.

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

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

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).
