Perry & Young’s Premier Porcelain-Fused-to-Zirconia has all of the characteristics of our Classic PFZ, but with complex layers for the highest esthetic appearance and also to better match existing teeth. Premier PFZ features custom shading build up by one of our master ceramists. Our Premier PFZ includes a custom shade appointment to match existing teeth.
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).
