Our porcelain-fused-to-zirconia crown and bridge restorations feature a solid zirconia substructure with porcelain layering. PFZ provides a combination of strength and esthetics in a long-lasting solution. PFZ is ideal for esthetic restorations because it provides more room for ceramic veneers. Indicated for anterior and posterior crowns, crowns over implants, and bridges of up to 14 units. Not indicated for bruxing patients. Flexural strength up to 1200 MPa. Available in all VITA® classical and 3D shades.
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

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).
