PFZ

At PM Newton Dental Ceramics Dental, we provide a range of PFZ crowns that bring together the strength of a metal crown with the realistic beauty and opalescence of zirconia.

  • 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.
