“…However, it is essential to acknowledge the limitations of this study due to the absence of scanning electron microscopy, which offers superior microstructural insights. Additionally, surface free energy assessments help predict adhesion quality and pretreatment effectiveness 40 . Given that combining scanning electron microscopy and surface free energy assessments can enhance our understanding of CCRBC bonding properties, future studies should consider these techniques for more comprehensive surface evaluation.…”

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.

Background: The purpose of this study is to investigate the performance and fracture resistance of different resin-matrix ceramics materials as implant-supported single crowns with respect to the abutment design (crown thickness: 1 mm, 2mm and 3 mm). Methods: Forty-eight aboutments and crowns were fabricated on implants right lower first molar simulating. Two resin-matrix ceramics materials for dental crowns were selected for study, (1)glass-ceramic in a resin interpenetrating matrix (Vita Enamic, Vita, Germany) and (2) resin-based composite with nanoparticle ceramic filler (Lava Ultimate, 3M ESPE, USA). The abutment is designed into the following three types: 1 mm thickness crown + custom titanium abutment, 2 mm thickness crown + custom titanium abutment and 3 mm crown + prefabricated titanium abutment. The experiment was divided into 6 groups (n=8) according to the crown materials and the abutment designs. After 10,000 thermocycling, fracture resistance was measured using a universal testing machine. The statistical differences in various groups were analyzed with ANOVA test followed by a post hoc Tukey’s honestly significant difference test. The surface of the fractured specimen was examined with the scanning electron microscopy (SEM). Results: 2-way ANOVA revealed that the factor of the abutment designs (F=28.44，P=1.52x10-8<0.001) and the crown materials (F=4.37，P=0.043<0.05) had a significant effect on the fracture resistance of implant crown restoration. The Lava Ultimate-2 mm group showed the highest fracture resistance of 2222.74±320.36 N, and the Vita Enamic-3 mm group showed the lowest fracture resistance of 1204.96±130.50 N. Most of the 1 mm and 2 mm groups had partial crown fracture that could be repaired directly with resin, while the 3 mm group had longitudinal fracture of the crown, and the crown was detached from the abutment. Conclusion: Based on the in vitro data of this study, the fracture resistance of the 2 mm thick resin-matrix ceramics crown design is higher than that of the 1 mm and 3 mm groups. The 2 mm thick resin-matrix ceramics crown and personalized abutment are an option to replace zirconia as an implant crown restoration.
