The total of 149 slices were analysed with stereomicroscope for microleakage and sealant penetration. The key difference between infiltration and percolation is that the infiltration refers to the filtration of rainwater from the surface of the ground while percolation refers to the filtration of infiltered water through soil particles and porous materials such as fractured rocks etc. Group 1 with bulk technique (4 mm) and group 2 … percolation. Rinke et al. Once the dental pieces were prepared, the teeth were mounted in a Type IV ResinRock plaster base (WhipMix, Louisville, Ky) with the main teeth axis oriented perpendicularly to the pedestal surface to simulate an arch, and thus facilitating the creation of an individual tray and impression. Flowable resin composite when used as a 1mm thick liner under a packable resin composite at the gingival margins showed overall less microleakage than the other two groups to some On the other hand, the second hypothesis, whether there is no correlation between marginal discrepancy and microleakage, was confirmed. On the other hand, percolation involves filtration through a porous material. Moreover, after full polymerization or setting of the cement, no microleakage Microleakage levels were highest in the charisma group, while statistically there was no significant difference between the tPh Spectrum and Gradia Direct Anterior groups (p>0.05). This data also revealed that significant statistical differences were found for 2% basic fuchsine solution microleakage in Cerec inLab CAD/CAM ceramic crown-copings when compared with the Procera and KaVoEverest systems. ... percolation. Holmes, J.R., Bayne, S.C., Holland, G.A. Conclusions: Cerec inLab CAD/CAM crown-copings showed significantly higher values for microleakage and marginal discrepancy in comparison with Procera and KaVo Everest CAD/CAM crown-copings.
