ABSTRACT
Statement of the Problem:
The castability of nonprecious gold color alloy using torch/ centrifugal and induction/vacuum-pressure casting techniques has not been studied yet.Purpose:
This study was conducted to compare the castability of nickel chromium, cobalt-chromium and nonprecious gold color alloy using torch/centrifugal and induction/ vacuum-pressure casting techniques. Materials andMethod:
In this in vitro study, a total number of 54 identical acrylic wax meshes were prepared and divided into 6 different groups of 9 each. Group 1 nickel-chromium alloy, which was casted with induction technique. Group 2 nickel-chromium alloy was casted with centrifugal technique. Group 3 cobalt-chromium alloy was casted with induction technique. Group 4 cobalt-chromium alloy was casted with centrifugal technique. Group 5 nonprecious gold color alloy was casted with induction technique. Group 6 nonprecious gold color alloy was casted with centrifugal technique. Then castability of specimens was measured using modiï¬ed Whitlock's method. The results were analyzed using two way ANOVA and post hoc tests.Results:
ANOVA test revealed no statistically significant difference between different alloys with a p Value of 0.313. Moreover, it represented no significant differences within the groups regarding alloy types and casting techniques with a p Value of 0.511 and 0.682, respectively.Conclusion:
No significant difference was found in the castability value of nickel-chromium, cobalt-chromium, and nonprecious gold color alloys. In addition, the castability value of three alloys tested in this study was not different by using torch/centrifugal or induction/vacuum-pressure casting machines.
