How do you seat and cement a PFZ restoration?

A PFZ is designed for conventional cementation, which keeps delivery straightforward. Disciplined cement control is what separates a clean, durable result from one prone to gingival problems and recurrent decay.

Cement options and seating

Clean the inside of the crown with a cleaning solution before delivery. ROE specifies cementing PFZ with resin-modified glass ionomer, dual-cure resin cement, or zinc phosphate cement. Apply a thin layer of cement along the internal walls, avoiding excess near the margins, then seat the crown under firm finger pressure, have the patient bite down, and stabilize it (for example with a wood stick across the occlusion) while the cement sets.

Why cement volume control is critical

Excess cement is one of the most common and most damaging delivery errors. Studies cited by ROE indicate clinicians routinely use about 20 times more cement than needed, with roughly 95% extruding beyond the margins. Excess subgingival cement drives gingival inflammation, bleeding, and bone loss, and it obscures the margin during cleanup. Apply only a thin film: enough for retention, not enough to extrude.

Clinical rule of thumb: A thin film of cement kept back from the margins protects the tissue, the margin seal, and the longevity of the restoration.

Removing excess and finishing

Remove excess cement while it is still in the rubbery stage, using floss and scalers to clean sub gingivally and around every margin. Then check and adjust proximal contacts, emergence profile, and occlusion in centric and excursive movements, and polish all adjusted surfaces. Thorough cleanup and a smooth, well-adjusted surface support both periodontal health and the long-term durability backed by ROE's 2-year warranty.
