Comparison of the marginal fit of soft-machined monolithic zirconia crowns
Abstract
Aims: The aim of this study was to compare the marginal fit of five different soft machined monolithic zirconia materials.
Methods: A mandibular right first molar on an acrylic model was prepared with standardized dimensions using diamond burs. Fifty metal duplicates were fabricated via laser sintering with Co-Cr alloy and divided into five groups (n=10). All duplicates were scanned using a CAD/CAM system, and zirconia crowns with a 1.5mm occlusal thickness and 20µm cement space were produced. Following sintering, marginal gaps were measured using the silicone replica technique. The obtained silicone replicas were sectioned into four parts mesiodistally and buccolingually using a scalpel. The marginal gaps of the samples were examined using a stereomicroscope under 10×magnification. Marginal gap measurements were performed at four specific points where the crown margin was closest to the cemento-enamel junction: mesial, distal, buccal, and lingual. For each crown, the measurements were repeated three times, and the mean value was recorded. A total of 600 measurements were performed for 50 crowns. Statistical analysis was conducted using one-way ANOVA and Tukey’s HSD test (p<0.05).
Results: Significant differences were found among the zirconia groups (p<0.001). Zenostar exhibited the highest marginal gap (92±22µm), followed by Katana (81±18µm) and Incoris TZI (66±20µm). The lowest values were recorded in the Bruxzir (46±9µm) and Prettau (48±23µm) groups. Zenostar and Katana showed significantly larger marginal gaps compared to Prettau and Bruxzir (p<0.05), while Incoris TZI presented intermediate values without significant differences.
Conclusion: All tested monolithic zirconia materials demonstrated clinically acceptable marginal fit. However, notable differences were observed among materials, with Bruxzir and Prettau showing superior marginal fit compared to Zenostar and Katana.
