Abstract
Purpose: The purpose of this study was to evaluate bond strength of Metal Disk alloy and casting alloy.
Methods: Metal specimens were divided into 4 groups for each alloy. Three point flexural test were used to measure the bond strength of CAD/CAM metal alloy and casting alloy. Statistical analysis was done using the Statistical Package for Social Sciences version 19.0 for Windows. As for the analysis methods, the study used Kruskal-Wallis test.
Results: The average bonding strengths of Group 1 to porcelain was 36.7±9.90 MPa, Group 2 to porcelain was 37.68±4.51 MPa, Group 3 to porcelain was 36.43±6.57 MPa, Group 4 to porcelain was 42.88±6.81 MPa, Each group was not significantly different.
Conclusion: Bond strength of Casting alloy is equal to or higher than bond strength of CAD/CAM Metal Disk alloy. Alloy clinical bond strength is 25 MPa, So CAD/CAM Metal Disk alloy can be used as dental material.
