Z-Plus Hybrid

Our zirconia hybrid restoration is fabricated out of our exceptional Z-Plus and utilizes esthetic porcelain. Available as a micro-cutback with porcelain layering on the facial, this restorative option is ideal for anterior cases. The Z-Plus zirconia ensures strength for a long-lasting solution. The porcelain provides translucent beauty that will allow the crown to seamlessly blend in with the rest of your patient's smile.

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).
