Porcelain Fused to Zirconia

A zirconia substructure provides warmer, more lifelike tones when compared to conventional PFM. Our PFZ features the durability of a zirconia coping with the superior aesthetics of porcelain stacked by our master ceramists. With copings fabricated harnessing the precision of CAD/CAM technology, our PFZ seats easily and with little to no chairside adjustment.

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.

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.

Feather-edge margin preparations are indicated for full-cast restorations.

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).
