- Abstract
- Purpose: This study aimed to investigate the shear bond strength for non-precious alloy castings without beryllium, which has been used repeatedly for economical reason.
Methods: The Schmitz-Schulmeyer test method was used to evaluate the shear bond strength between the nonberyllium Ni-Cr alloy Vera Bond 2V(AlbaDent, Inc. USA) and the Ceramco 3(Dentstply, York, PA, USA) porcelain powder.
The maximum loading and shear bond strength were measured. The average shear strength( ) was analyzed with the one-way ANOVA and the Tukey’s test( =.05). The fracture specimens were examined using Microscope to determine the failure pattern.
Results: The mean shear bond strengths(SD) in MPa were group A(100% new metal) control 28.72(3.31); group B(50% new + 50% reused) 27.28(1.13); group C(all reused) 26.61(5.47). Microscope examination showed that group A and B specimens presented mixed failure, and group C specimens showed adhesive failure.
Conclusion: In conclusion, forward this non-precious alloy dose not contain beryllium for how should use a more systematic study and for future advanced research is performed giving effect to be considered desirable.
