  title={Marginal and internal gaps of crown and bridge substructure of two all-ceramic systems},
  author={Bundhit Jirajariyavej and Daungjan Siangsiaw and Chuchai Anunmana},
Objective: The objectives of this study were to compare the marginal and internal gaps of two ceramic systems as well as the marginal and internal gaps between single crowns and three-unit fixed dental prostheses (FDPs) substructures. Materials and Methods: Ceramic substructures were fabricated using CAD/CAM (LavaTM Zirconia) and heatpress technique (IPS e.max® Press) as premolar and molar single crowns and three-unit FDPs (4 groups, n=10). Marginal and internal gap widths were determined and… Expand

Figures and Tables from this paper


Precision of fit: zirconia three-unit fixed dental prostheses
The results suggest that the accuracy of both investigated systems is satisfactory for clinical use, and two out of three measurement locations were significantly different. Expand
Internal fit of two all-ceramic systems and metal-ceramic crowns
The internal fit (IF) of glass-infiltrated alumina, yttria-stabilized tetragonal zirconia polycrystals, and metal-ceramic crowns was investigated to find that the total mean achieved by all groups was within the range of clinical acceptability. Expand
Clinical fit of four-unit zirconia posterior fixed dental prostheses.
The values obtained were clinically satisfactory and showed that semisintered zirconia blanks could be used for the fabrication of four-unit FDPs. Expand
A comparison of Vertical Marginal Fit of three different types of All ceramic crown restorations ( An in vitro study )
Background:The objective of this in vitro study was to evaluate and compare the vertical marginal fit of crowns fabricated with three different techniques: ZrO2 CAD/CAM,ZO2; copy-milling machine andExpand
Effect of sintering on the marginal and internal fit of CAD/CAM-fabricated zirconia frameworks.
Marginal and internal fit of both APA and APPA were within clinical acceptance, however, the marginal gap and thickness of the cement layer on the axial surface of the pontic side ofAPA andAPPA were slightly higher than those of the non-pontic side. Expand
Influence of marginal fit and cement types on microleakage of all-ceramic crown systems.
Lower levels of microleakage were recorded with self-adhesive resin cement, while CAD/CAM-fabricated ZrO2 copings showed smaller marginal discrepancy and less microle leakage in comparison to cast Cr-Co. Expand
Evaluation of marginal and internal fit of ceramic crown copings.
Different levels of adaptation were found for the different experimental groups and for theDifferent evaluation methods, however, all IS evaluated showed clinically acceptable values of marginal and internal adaptation. Expand
Marginal fit of 14-unit zirconia fixed dental prosthesis retainers.
Fourteen-unit fixed dental prosthesis showed significantly higher marginal openings than single crowns fabricated under the same conditions, however, both restorations showed clinically acceptable marginal openings. Expand
The influence of finish line curvature on the marginal gap width of ceramic copings.
The greater the finish line curvature, the wider the marginal gap widths for the 3 ceramic systems. Expand
In vitro evaluation of marginal adaptation in five ceramic restoration fabricating techniques.
Marginal adaptation values obtained in the compared systems were within clinically acceptable limits, and cementation causes a significant increase in the vertical marginal discrepancies of the test specimens. Expand
