“…In partial ceramic restorations IDS is thought to improve the adhesion resulting in improvement of the fracture strength. [37] Although we did not find any statistically significant difference in the performance of partial restorations using IDS or DDS some failures only occurred in the DDS group; tooth chipping and fractures. When using IDS with indirect bonded restorations, the delayed placement of the restorations and postponed occlusal loading facilitates the dentin bond to develop without stress.…”

ObjectivesThe survival and success rate and the quality of survival of partial ceramic restorations bonded employing Immediate (IDS) or Delayed Dentin Sealing (DDS) in vital molar teeth were evaluated in a randomized clinical trial with within-subject comparison study.Materials and Methods 30 patients received two lithium disilicate ceramic (IPS-e.max press, Ivoclar Vivadent) partial restorations on vital first or second molar teeth (N=60). The two teeth randomly received either IDS (test group, n=30) or DDS (control group, n=30). Partial ceramic restorations were luted (Variolink Ultra, Ivoclar Vivadent) two weeks after preparation. Evaluations were performed at 1 week, 12 months and 36 months post-operatively, using qualitative (FDI) criteria. Representative failures were evaluated microscopically (SEM) and by means of simplified qualitative fractography analysis. ResultsOne absolute failure occurred in the DDS group due to (secondary) caries. The overall survival rate according to Kaplan-Meier after 3 years was 98.3% (FDI criteria score 1-4, n=59) and the overall success rate was 85% (FDI criteria score 1-3, n=51), with no significant difference between restorations in the IDS and DDS group (p=0.32;Kaplan-Meier, Log Rank (Mantel-Cox), CI=95%). For the quality of the survival, no statistically significant differences were found between IDS and DDS (p=0.7;, CI=95%) restorations on any followup timepoints for any of the FDI criteria (Wilcoxon, McNemar, p>0.05).. ConclusionAdhesively luted partial ceramic restorations in vital molar teeth have a good prognosis, however IDS did not show any differences in success and survival rates after 3 years of function.

“…The sample size of each group was ten in the present study; however, Quinn and Quinn recommended a sample size of 30 when Weibull analysis should be conducted . However, several studies have been conducted on fewer than 30 specimens, and Weibull analysis was used . Although a smaller sample size yielded enough data to analyze the Weibull modulus, it is a limitation of the current study.…”

“…In Sieper's study, VITA SUPRINITY ® showed higher strength with a fracture resistance that was even higher for reduced thicknesses (0.8-1 mm) compared with IPS e.max CAD ® . Likewise, in an assay of adhesion to dentin, Van den Breemer [46] found improvements in the behavior of ceramic materials when the adhesion technique involved immediate dentin sealing, as this established higher bond strength at the tooth-cement-restoration interfaces. However, Carvalho et al [37] did not find significant differences when comparing the fracture resistance of lithium disilicate and RNC after cyclic isometric loading.…”

“…Its composition includes pre-hydrolyzed silane monomers, which are known to present less stability and efficacy than non-hydrolyzed silane [45]. These characteristics could influence the adhesion process of this resin nanoceramic, making its cement-restoration interface more susceptible to hydrolytic degradation in the oral medium in the long term [46].…”

Background and Objectives: To evaluate in vitro the fracture resistance and fracture type of computer-aided design and computer-aided manufacturing (CAD-CAM) materials. Materials and Methods: Discs were fabricated (10 × 1.5 mm) from four test groups (N = 80; N = 20 per group): lithium disilicate (LDS) group (control group): IPS e.max CAD ® ; zirconium-reinforced lithium silicate (ZRLS) group: VITA SUPRINITY ® ; polymer-infiltrated ceramic networks (PICN) group: VITA ENAMIC ® ; resin nanoceramics (RNC) group: LAVA™ ULTIMATE. Each disc was cemented (following the manufacturers' instructions) onto previously prepared molar dentin. Samples underwent until fracture using a Shimadzu ® test machine. The stress suffered by each material was calculated with the Hertzian model, and its behavior was analyzed using the Weibull modulus. Data were analyzed with ANOVA parametric statistical tests. Results: The LDS group obtained higher fracture resistance (4588.6 MPa), followed by the ZRLS group (4476.3 MPa) and PICN group (4014.2 MPa) without statistically significant differences (p < 0.05). Hybrid materials presented lower strength than ceramic materials, the RNC group obtaining the lowest values (3110 MPa) with significant difference (p < 0.001). Groups PICN and RNC showed greater occlusal wear on the restoration surface prior to star-shaped fracture on the surface, while other materials presented radial fracture patterns. Conclusion: The strength of CAD-CAM materials depended on their composition, lithium disilicate being stronger than hybrid materials.
