SUMMARY Objective To evaluate the shear bond strength (SBS) of three self-adhesive resin cements and a resin-modified glass ionomer cement (RMGIC) to different prosthodontic substrates. Materials and Methods The substrates base metal, noble metal, zirconia, ceramic, and resin composite were used for bonding with different cements (n=12). Specimens were placed in a bonding jig, which was filled with one of four cements (RelyX Unicem, Multilink Automix, Maxcem Elite, and FujiCEM Automix). Both light-polymerizing (LP) and self-polymerizing (SP) setting reactions were tested. Shear bond strength was measured at 15 minutes and 24 hours in a testing device at a test speed of 1 mm/min and expressed in MPa. A Student t-test and a one-way analysis of variance (ANOVA) were used to evaluate differences between setting reactions, between testing times, and among cements irrespective of other factors. Generalized linear regression model and Tukey tests were used for multifactorial analysis. Results Significantly higher mean SBS were demonstrated for LP mode relative to SP mode (p<0.001) and for 24 hours relative to 15 minutes (p<0.001). Multifactorial analysis revealed that all factors (cement, substrate, and setting reaction) and all their interactions had a significant effect on the bond strength (p<0.001). Resin showed significantly higher SBS than other substrates when bonded to RelyX Unicem and Multilink Automix in LP mode (p<0.05). Overall, FujiCEM demonstrated significantly lower SBS than the three self-adhesive resin cements (p<0.05). Conclusions Overall, higher bond strengths were demonstrated for LP relative to SP mode, 24 hours relative to 15 minutes and self-adhesive resin cements compared to the RMGICs. Bond strengths also varied depending on the substrate, indicating that selection of luting cement should be partially dictated by the substrate and the setting reaction.

Purpose: The aim of the study was to evaluate the shear bond strength of CAD/CAM ceramics to dentin after cementation with conventional or self-adhesive resin cements. Methods: Three self-adhesive, self-etching cements (Panavia SA, RelyX U200, Maxcem Elite), and one conventional cement (Panavia V5), were selected to lute three CAD/CAM ceramics (IPS Empress CAD, IPS e.max CAD, IPS e.max ZirCAD) onto the dentin. The bond strength was evaluated using a shear strength test according to the PN-EN ISO 29022:2013-10. Evaluation of the differences was performed using the Statistica software. Failure modes were analyzed using a light microscope. Results: All the studied cements differed (regardless of the ceramic type) in the bond strength. The highest bond strength was observed in Panavia V5, lower – in RelyX U200 and Panavia SA, and the lowest – in Maxcem. For IPS e.max ZirCAD, it was observed that compared to Panavia V5, the other cements were characterized by a significantly higher bond strength. For the IPS Empress CAD and the IPS e.max CAD, Panavia V5 displayed the highest bond strength. For all the studied self-adhesive cements, the failure of adhesion between the cement and dentin was predominant mode. Conclusions: Significant differences were found in the shear bond strengths of the CAD/CAM ceramics luted to dentin using tested self-adhesive and conventional cements. The bond strength depended on the combination of ceramic and cement. The IPS e.max ZirCAD had the highest bond strength to dentin after cementation with RelyX U200, while the IPS Empress CAD and IPS e.max CAD – with Panavia V5.

Com o aumento da exigência estética dos pacientes e o desenvolvimento de materiais e técnicas odontológicas restauradoras problemas como alteração de cor e forma tem sido melhor resolvidos garantindo naturalidade e longevidade aos procedimentos restauradores. Este trabalho objetivou apresentar um relato de caso clínico de reabilitação estética do sorriso, descrevendo protocolo clínico de laminados cerâmicos e coroas totais “metal free” desde o planejamento até a cimentação definitiva. Paciente do gênero feminino, apresentou insatisfação com a estética de seu sorriso, principalmente em relação a coloração de seus dentes. Durante avaliação clínica, constatou-se comprometimento estético dos elementos dentais 11, 12 e 21 com alteração de cor e desequilíbrio dimensional. Esses dentes tinham grande restaurações resina composta, o que os tornava opacos e sem brilho. O tratamento proposto consistiu na realização de clareamento dental e posteriormente laminados cerâmicos nos dentes 12, 13, 14, 22, 23 e 24 e coroas totais “metal-free” nos elementos 11 e 21, utilizando um sistema cerâmico a base de dissilicato de lítio. Após o relato deste caso clínico, pode-se concluir que com o advento das cerâmicas ácido sensíveis e da cimentação adesiva os tratamentos reabilitadores estéticos têm proporcionado um resultado estético e funcional satisfatório.Descritores: Facetas Dentárias; Odontologia; Dentística Operatória.ReferênciasLima AF, Carvalho JFO, Cravo FL.

The aim of this study was to compare the shear bond strength (SBS) of two resin cements bonded to four leucite-reinforced ceramics after one week and one year of aging. Material and methods: Forty ceramic blocks (4 mm wide, 14 mm length, and 2 mm thick) were used (1 week) and reused at the back side (1 year). The blocks were abraded with aluminum oxide (90 µm) and randomly divided into eight groups for each time. Two dual resin cements (RelyX ARC and RelyX U200 self-adhesive, 3M ESPE) were bonded to ceramics Creapress (CRE – Creation / Klema), Finesse All-Ceramic (FIN – Dentsply / Ceramco), IPS Empress Esthetic (IEE – Ivoclar Vivadent) and Vita PM9 (PM9-Vita). For each resin, time, and ceramic block, after applications of the 10% hydrofluoric acid (for 1 min) and silane, 3 Tygon cut tubes were positioned over each block and filled in with the resin cements (light-cured for 40 s). The tubing molds were removed to expose the bond specimens as cylinders (area=0.38 mm2) stored in relative humidity at 24±2°C for one week and at 37±2°C for one year. All bonds were tested in an Instron in shear (applied of the base cylinder with a thin wire - 0.25 mm) at speed of 0.5 mm/min, until failure. Results: The results were analyzed by ANOVA (resin cements, ceramic systems, and time) and Tukey test (p<0.05) for rank ordering of SBS. The FIN and IEE ceramics did not show significant SBS decreasing on aging with U200. The mean SBS decreasing for all the ceramics was 36% with ARC and 14% with U200 cement. Conclusion: The SBS of ARC cement were significantly lower for all ceramics with aging than that of U200 cement. The SBS of ARC cement was also weakened by aging. FIN ceramic + U200 cement proved to be the most stable and strongest bond strength, and PM9+ARC cement proved to be the weakest bond strength with low stability.
