Abstract
Purpose: The purpose of this study was analysis of quality of fixed prostheses fabricated by dental CAD/CAM system.
Methods: The ten same cases of stone models were manufactured by dental scannable model, and stone models were scanned using the dental scanner for changing digital model. Ten digital models were completed. The design of zirconia core for zirconia based all-ceramic crown was conducted by the dental CAD program. The samples were fabricated using the pre-sintered zirconia block by dental milling machine. Marginal gaps were analyzed using by silicone replica technique at the eight parts for quality analysis of samples. One-way ANOVA was used for statistical analysis( =0.05).
Results: The mean for marginal gaps were 93.2~99.1 at the eight parts. One-was ANOVA didn’t show significant differences(p=0.089).
Conclusion: The fixed dental prostheses fabricated by dental CAD/CAM were within clinically acceptable range.
