What are the full specifications of a PFZ restoration?

This article is a quick-reference specification sheet for the PFZ (Porcelain Fused Zirconia) restoration. The narrative articles (material science, indications, preparation, records, workflow, seating, and administration) expand on each line below.

At-a-glance specifications

Specification Detail
Description A strong 4Y zirconia core layered with porcelain; balances strength and esthetics while being more affordable than full precious-metal options
Materials 4Y zirconia core and low-fusing porcelain; copings available in regular, translucent, and bleached shades
Applications Anterior crown, anterior bridge
Tooth shades All 16 VITA shades and 4 bleach shades (Vita Classical and Vita 3D-Master veneering systems)
Strength (ROE listed) 250 MPa
Esthetics ★★★★★
Wear ★★★★
Patient visits (est.) 2
Days in lab 9 days in lab (does not include shipping)
Warranty 2 years
Records Traditional or digital impressions, impression of prepared teeth, opposing and bite registration, and shade
Preparation Chamfer or shoulder prep with 4–8° axial wall taper; minimum 1 mm marginal reduction; minimum 1.5 mm occlusal clearance; minimum 1.5–2.0 mm occlusal reduction; no knife-edge margins or sharp/right angles
Seating Clean the inside of the crown with cleaning solution; cement with resin-modified glass ionomer, dual-cure resin cement, or zinc phosphate cement

Reading the strength figure

ROE lists PFZ at 250 MPa in its fixed-restoration comparison. As with any layered restoration, this figure reflects the veneering ceramic rather than the zirconia coping; the 4Y zirconia core itself provides the structural strength, which is why PFZ remains a reliable full-coverage option despite a modest ceramic-strength number.

Benefits summary

ROE's PFZ page highlights a high level of lifelike esthetics, superior marginal fit with optimal porcelain support, and highly predictable, durable outcomes. The metal-free zirconia core also eliminates gray margins and supports favorable soft-tissue response.

For prices, do not quote a figure; direct the reader to the pricing request page.
