Abstract EN
Background: As the development of zirconia crown using CAD/CAM technology, the usage of full zirconia crown is gradually increased.
The aim of this in-vitro study was to evaluate and contrast the vertical marginal fit of single allceramic translucent zirconia crowns constructed from different brands translucent zirconia blanks.
Materials and Methods: An acrylic resin model of a left maxillary premolar was prepared all around the tooth with (1 mm) depth and 3D scanning to get fifteen STL files, then distributed into three groups (Imes-icor, Whitepeaks and Dental direct), 3D scanning and milling machine by Imes-icor CAD/CAM devise.
Marginal gaps along vertical planes were measured at four indentations at the (mid mesial, mid distal, mid buccal, mid palatal) using a light microscope at a magnification of x100.
One-way ANOVA, LSD tests were performed to determine the mean and standard deviation of the three blanks groups.
Results: Statistically high significant difference (p < 0.00) was found between the groups.
The marginal gap value of the groups varied Whitepeaks crowns was (105.42 ± 7) μm, which was significantly higher than the two overall mean marginal gap measured for the Imes-icor crowns (59.3 ± 4) μm and Dental direct crowns (54.5 ± 4.9) μm, the Dental direct which was lowers overall mean vertical gap measurement.
Conclusions: The marginal gap values of Dental direct crowns is considerably lower than that of Whitepeaks crown, The marginal gap values of all the groups made of monolithic high translucent Y-TZP demonstrated acceptable marginal gaps values.
