Report Errors
Purpose : The purpose of this study was to compare the marginal fit of monolithic zirconia restorations fabricated form the conventional and the digital impression technique.
Materials and methods : Ten patients were restored with monolithic zirconia restorations fabricated from the digital and the conventional impression technique. Before definitive insertion, silicone replicas were produced from all twenty crowns. The silicone replicas were cut in three sections; each section was evaluated at two points. The measurement was carried out by using a measuring microscope (Olympus BX 51) and I-Solution. Data from the silicone replica scores were analyzed by Shapiro-Wilk test for normal distribution and the t-test for equality of two population’s mean. All tests were performed with α-level of 0.05.
Results : The average marginal gaps of monolithic zirconia restorations were 133.81±36.46 μm for the conventional impression technique, 90.07±9.47 μm for the digital impression technique. No statistical differences were found between the two impression techniques
Conclusion : Both prostheses presented clinically acceptable results with comparing the marginal fit.
