One high gold and five low gold porcelain bonding alloys were examined for dimensional changes after fusion of the porcelain. With the same processing techniques applied, the individual firings resulted in varying changes in the accuracy of fit of the tested alloys. Averaging at -0.09 mm Bond-on 4 showed the greatest marginal discrepancies and this was the only alloy that displayed a statistically significant difference to Degudent U.
