PORCELAIN FUSED TO ZIRCONIA
Standard in-lab turn-time: 5 Days
An updated take on conventional PFM, porcelain fused to zirconia crowns place esthetic layered porcelain on a zirconia coping. Digitally fabricated for ultimate precision, the zirconia coping also improves esthetics, eliminating dark areas at the margin and allowing porcelain to appear more lifelike.
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.
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.
- 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).
