INTEGRITY NOBLE WHITE PORCELAIN ALLOY A white, noble, 75% Pd porcelain dental alloy with a small percentage of silver, INTEGRITY is considered to be “tried and true.” INTEGRITY’s uniform, light-gray oxide makes opaque coverage easy. Well known for its small grain size, INTEGRITY is resistant to hot tearing. INTEGRITY has a coefficient of thermal expansion that works with all major porcelains on the market. Coefficient of Thermal Expansion Grain Size Contains less than 1% Ruthenium, Rhenium Tensile Yield Strength Tensile Elongation Classification - Noble Ultimate Tensile Strength 114,000 psi (790 MPa) Elastic Modulus PROCESSING TECHNIQUE WAXING Wax to a minimum thickness of 0.4mm for single units and 0.5mm for bridge work. Indirect spruing with 10 gauge sprues from an 8 gauge runner bar is recommended. If multiple units are individually sprued in a single ring, units should be separated by a minimum of 4mm (3/16”). A high heat phosphate bonded investment must be used. A carbon free investment is preferred. Melt in a high heat crucible using a multi-orifice torch with gas pressure at 10psi and oxygen pressure at 20psi. The ingots will melt together forming a single fluid pool. Heat with the reducing portion of the flame. Cast after heating for 10 seconds after the melt surface appears free of oxides. The casting temperature is 2475ºF (1355ºC). Do not use a casting flux. Finish all surfaces to receive porcelain coverage with aluminum oxide stones and discs. Blast surfaces with nonrecycled, 50 micron, white aluminum oxide at a pressure of 80psi. Ultrasonically clean for 10 minutes in distilled or deionized water. Oxidize under vacuum by heating from 1200º to 1850ºF (650º to 1010ºC) at 145°F/min (80°C/min). Hold for 5 minutes under vacuum at the upper temperature. Remove, bench cool, and proceed with opaquing according to the porcelain manufacturer’s instructions.
