“…Glass ceramics strengthened with lithium disilicate (13), zirconia strengthened by lithium silicate and hybrid porcelain material have recently been developed (14). The principal motivation behind these improvements is to produce restorations that are durable and resistant to forces in oral cavity without affecting esthetic outcomes (15). Fracture tests of ceramic materials are performed with shear tests, three or four point bending tests by planning geometric examples.…”

INTRODUCTION:Ceramic inlays have picked up prominence due to their superior esthetic characteristics and work-ability. In addition, they allow chair-side restorations to be completed in one appointment. OBJECTIVE:The aim of this study was to assess the in-vitro fracture resistance of three CAD/CAM ceramic materials. MATERIALS AND METHOD: Mesio-occluso-distal (MOD) inlays (n=33) were fabricated from three CAD/CAM materials: Lithium disilicate glass ceramic (IPS-EMAX CAD), Zirconia-reinforced lithuim silicate (CELTRA-DUO) and hybrid composite filled with zirconium silicate particles (SHOFU HC BLOCK). Digital impressions of the inlay cavities prepared in the maxillary first premolar teeth were taken by CEREC scanner then the restorations were milled using CEREC MCXL milling machine. Samples were cemented to MOD inlay cavities with resin cement (RelyX U200, 3M ESPE) and then fracture resistance test was performed by the Universal Testing Machine. RESULTS:The fracture resistance values of inlays fabricated from lithium disilicate EMAX CAD (1104.627) was higher than those from CELTRA DUO (937.024) followed by those of SHOFU (724.417). There was a statistical significance between group A (EMAX) and group C (SHOFU) p=0.005. The mode of failure of the restorations presented mixed types of failure (cohesive and catastrophic). CONCLUSION: Strengthening with zirconia particles did not have a positive influence on the fracture resistance of neither the glass ceramic nor the composite resin materials tested.

The aim of this study was to investigate the effect of deposition temperature on the structural, optical, morphological and dielectric properties of yttria-stabilised zirconia (YSZ) films prepared by sol-gel spin-coating method. X-ray diffraction (XRD) measurements of YSZ films showed that the peaks of the cubic phase were prominent and the peak intensities increased with deposition temperature. The crystallite size, dislocation density and microstrain of the thin films were identified by XRD. It was observed that the crystal size of the YSZ thin films increased from 16 nm to 22 nm with the deposition temperature. The surface roughness of the thin films was found to have changed as revealed by Atomic Force Microscopy (AFM) measurements. The roughness increased from 7.72 nm to 11.92 nm with increasing temperature. The optical transmittance of the YSZ thin films was investigated in the wavelength range 200-900 nm and was found to increase slightly with increasing deposition temperature. Metal-Oxide-Semiconductor (MOS) devices were fabricated from these YSZ materials for dielectric characterization. The dielectric properties of the Ag/YSZ/n-Si MOS structure were investigated. It was found that the capacitance, conductivity and other dielectric parameters of these structures are strongly frequency dependent.

The aim of this study was to systematically compare the bond strength of self-adhesive and self-etch or total-etch resin cement to zirconia. The PubMed, ISI (all), and Scopus databases were searched for the selected keywords up to November 1, 2021, without date or language restrictions. In vitro studies comparing the bond strength of self-adhesive and self-etch or total-etch resin cement to zirconia were eligible for inclusion in the study. The selected articles were divided into four groups based on the type of resin cement and the storage time. Statistical analysis was performed using the Biostat Comprehensive Meta-Analysis Software version 2 (α = 0.05). The effect of conventional cement ( Glass Ionomer (GI), Resin Modified Glass Ionomer (RMGI) and zinc phosphate) was analyzed using descriptive analysis. The initial search yielded 376 articles, of which 26 were selected after a methodological assessment. Two reviewers independently extracted data and assessed the risk of bias. The results showed that the immediate or delay bond strength of the self-adhesive resin cement to zirconia has no significant difference with the bond strength of self-etch resin cement to zirconia. The immediate and delay bond strength of total-etch cement-zirconia was significantly lower than that of self-adhesive cement-zirconia (P = 0.00). A descriptive analysis of the selected articles showed that the bond strength of self-adhesive resin cement to zirconia was significantly higher than total-etch cement. The results of the meta-analysis showed that both self-adhesive and self-etch resin cement (if applied according to their manufacturer’s instruction) are suitable for bonding to zirconia.

Abstract: In this study, we measured the bond strength; our most durable resistance groups were found to be, in order, Panavia-ceramics >Panavia-metal >Panavia-Zr >self-adhesive-ceramics >self-adhesive-Zr >and self-adhesive-metal.
