The Effect of Cooling Rate on the Apparent Bond Strength of Porcelain-Metal Couples,

Abstract

The effects of cooling conditions on the apparent bond strength of a dental porcelain fused to a cast substructure were studied. Under the conditions of this investigation, slow cooling of the porcelain-metal composite in an oven or rapid cooling in an ice chest from the maturation temperature of the porcelain resulted in the highest values of apparent bond strength. However, additional factors must be considered in the selection of a particular cooling method. From the present data, it would appear that cooling of a ceramo-metal restoration under a protective cover would provide the least risk to the integrity of the porcelain-alloy bond and to the surface of the porcelain.
