“…Micro-shear bond strength tests evaluate the adherence of luting materials and the mechanical behaviour of dental ceramics under a load that induces uniform stress concentration at the adhesive interfaces to determine the weakest area between the bonded surfaces [ 27 ]. In their studies, Farag, Maño and Sarahneh observed that reducing the size of bonded interfaces decreases the frequency of the defects and undesirable variations in the specimens and obtained lesser cohesive failures [ 28 , 29 , 30 ]. The stress distribution in the tested samples may be affected by many variables related to the fabrication of specimens, such as the type of cement, the application and the thickness of the cement layer, and also by the testing parameters, such as the distance from the testing device to the cement cylinder or the angle of force application [ 30 ].…”

A disadvantage of sample fabrication is the absence of the compression on resin cement while it is set on ceramic material, which could create a hydraulic force causing the penetration of the cement in all the micropores [ 14 ].…”

The objective of this study was to evaluate the influence of hydrofluoric acid (HF) and conditioning time on the micro-shear bond strength (µSBS) between dual-cure resin cement and glass-ceramic materials, such as lithium disilicate ceramic (IPS e.max CAD, Ivoclar Vivadent) (EX) and leucite-reinforced ceramic (IPS Empress CAD, Ivoclar Vivadent) (EP), and also a hybrid ceramic (Vita Enamic, Vita Zahnfabrik) (VE). Eighteen sections with 1 mm thickness were cut from each CAD/CAM material and randomly divided into three groups, according to the surface etching time (30 s, 60 s, 90 s). The surface treatment was performed using 9.5% HF acid gel, then resin cement was applied on the prepared ceramic plates and light cured. µSBS values between resin cement and the ceramic material were measured with a universal testing machine at a crosshead speed of 0.5 mm/min until the failure occurred. The fractured surfaces of specimens were microscopically evaluated, and failure modes were classified as: adhesive between resin cement and ceramic, cohesive within ceramic or cement and mixed failure. Surface roughness of etched samples was examined using a scanning electron microscope. Obtained data were statistically analysed using one-way analysis of variance (ANOVA) and Bonferroni post hoc test with a level of significance α = 0.05. The results of the statistical methods applied indicate that µSBS mean difference for leucite-reinforced ceramic (EP) was statistically significant (p < 0.05). However, µSBS values for hybrid ceramic (VE) and lithium disilicate ceramic (EX) were not affected, from a statistical point of view, by the conditioning time (p > 0.05).

Adhesive failures were predominant in polished specimens and after thermal cycling, making these results more informative for comparing different adhesives 21,22,37 …”

ObjectiveObtaining strong resin bonds to computer‐aided design and computer‐aided manufacturing (CAD‐CAM) resin‐based composites with dispersed fillers (CCRBCs) poses a challenge. Therefore, this study aimed to assess the effect of three universal adhesives and a two‐component silane coupling agent on the shear bond strength to three (CCRBCs).Materials and MethodsEight hundred and sixty‐four specimens of Brilliant Crios, Lava Ultimate, and Tetric CAD were polished or grit blasted, bonded with Adhese Universal DC, One Coat 7 Universal (OC7), and Scotchbond Universal Plus Adhesive (SBU) with or without a silane primer. Shear bond strength was measured after 24 h and 10,000 thermocycles. Linear regressions were performed (α = 0.05).ResultsAfter thermocycling, bond strengths were similar for the universal adhesives on polished Brilliant Crios and Lava Ultimate (p ≥ 0.408). Grit blasted Tetric CAD showed no significant differences (p ≥ 0.096). The silane primer had minimal impact on grit blasted Tetric CAD (p ≥ 0.384). The silane primer increased the bond strength of OC7 to Brilliant Crios (p = 0.001) but decreased the adhesion of SBU to Brilliant Crios and Lava Ultimate (p ≤ 0.018).ConclusionsBond strength of universal adhesives varied with CCRBC type. The two‐component silane coupling agent showed mixed effects on adhesive performance.Clinical SignificanceSelecting universal adhesives from the same CCRBC product line does not always guarantee superior bond strength. The efficacy of silane coupling agents differs based on the bonding substrate.

“…It does not require sintering.Fine margins can be achieved. It can be optimally polished with composite polishes, either intraorally or extraorally(32).In the study by Sarahneh et al(33), the highest bond strength values among resin matrix ceramic materials were observed for Grandio block and KZR CAD HR2. The application of only silane agent did not improve the bond strength.…”

CAD/CAM stands for computer-aided design and computer-aided manufacturing. CAD/CAM systems are used to speed up the design and production process in dentistry. With three-dimensional design and milling, various restorations can be fabricated without the need for a physical model. It is possible to scan the oral cavity and take digital impressions. The restoration can be designed with the software's help and fabricated in a shorter time without laboratory stages. In addition, the mechanical strength and edge compatibility of the restorations are improved and the fabrication of aesthetic restorations is aimed. CAD/CAM technology offers advantages such as time savings, elimination of potential errors, ease of use, and treatment quality. With the increasing demand for CAD/CAM restorations, various materials have been developed. Nowadays, CAD/CAM materials are widely available on the market and restorations can be produced from prefabricated blocks and discs. In this review, resin matrix CAD/CAM materials, which are relatively new on the market and claimed to have some positive properties for dental restorations, are described.
