The monolithic zirconia crown (3Y-TZP) had an elastic modulus of 210,000 MPa and a Poisson's ratio of 0.27 [21]. The Elastic modulus for cortical bone was set to 13,700 MPa and the modulus of cancellous bone to 1370 MPa, with a Poisson's ratio of 0.3 [22]. An elastic ...
The purpose of this study was to examine fracture strenght of inlay-retained adhesive bridges made out of different materials. Materials and methods. Six groups of eight specimens were fabricated out of the following materials: 1) metal-ceramics full-crown retained FPDs (control); 2) metal-...
Cylindrical cores were fabricated of either composite resin or heat-pressed zirconia-containing glass-ceramic (IPS Empress Cosmo, Ivoclar Vivadent). Following the construction of different Core materials, samples were subjected to push-out test set-up to Evaluate the impact of ...

Materials and methods: For eight patients who required a singular maxillary central incisor restoration, twenty-four crowns made of zirconia were created. These were grouped into three categories based on the shade and nature of zirconia (Zr) utilized (white core, co...
A crown was manufactured using four types of zirconia and LTD treated. Color measurements were performed, and the color difference (螖E00) before and after LTD was calculated. The microstructure was determined through X-ray fluorescence and X-ray diffractometry. Highly translucent zir...
Amber Lisi-POZ crown was produced by heat-pressing on the zirconia frame. Fracture strength test was performed at 10 degrees of inclination toward the load after bonding crown on metal abutment using dual-curing resin cement. Statistical analysis of fracture strength was conducted through Weibull ...
