The effect of oxidation heat treatment of porcelain bond strength in selected base metal alloys.
Base metal alloys have been widely used for fixed partial dentures in the past decade. The oxidation heat treatment (degassing) of these alloys is a controversial step to prepare the metal surface for bonding porcelain. This study evaluated the effect of oxidation heat treatment on the porcelain bond strength of base metal alloys and investigated composition changes that may have occurred during this process.
