TECHNICAL NOTES

If an adjustment is required on the ceramic, ALWAYS CEMENT OR BOND INTO PLACE BEFORE PROCEEDING. Then 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 (Brassler, Shofu and Vident).

Caution: While the recommended glazing temperature is 930° Celsius, the porcelain is very prone to slumping if the oven is not calibrated correctly. Therefore, FOR BEST RESULTS RETURN CROWN TO LAB FOR RESTAIN AND/OR REGLAZE. We cannot guarantee any crown not fired by us.

INDICATIONS / CONTRAINDICATIONS

NobelProcera is recommended for single unit crowns and bridges up to 14 units with a maximum 2 pontic span between abutments.

NobelProcera should not be used on patients with malfunctional occlusion such as bruxers or clenchers. NobelProcera should not be used as abutments for cast partials. NobelProcera should not be used in situations when preparation requirements cannot be achieved and when clearance is less than 1.5 mm. Maryland bridges cannot be fabricated using NobelProcera.

PREPARATION

Use typical all-ceramic preparation parameters: Chamfer or 90° rounded shoulder; 1.5 - 2 mm facial reduction, 2 mm flat occlusal reduction (no fossa prep), and no sharp angles. No bevels or deep shoulder preps. These are necessary to allow for best scanning capabilities.

Chamfer Margins - Correct preparation of the chamfer margins interproximally allows the appropriate bulk of porcelain.

CEMENTATION

Dual cure resins
Glass Ionomer Cement (Fuji GC)
Zinc Phosphate
Polycarboxylate
Resin Ionomer Cement (RelyX by 3M ESPE)
