“…Similar to the present study, Demirbuga et al found that there were significant differences between the bond strengths of preheated and nonheated composites to dentin surfaces. 23 Goulart et al evaluated the microtensile bond strength and adhesive interfaces of indirect restorations luted with preheated composite resin. 12 One resin cement (RelyX ARC) and two composite resins (Venus and Z250 XT) were used in their study, and the materials were preheated to 64°C.…”

Aim: To evaluate the shear bond strength (SBS) of resin cements, flowable composites, and a preheated composite in luting glass-ceramic to dentin. Materials and Methods: In total, 108 noncaries human third molar teeth embedded in acrylic blocks, grinded from the occlusal surfaces until dentin was exposed, and divided into 9 randomized groups ( n = 12). In total, 108 ceramic samples prepared in disc shape (3mm × 3mm) from IPS e. max CAD (Ivoclar Vivadent) blocks. Four adhesive resin cements: Variolink Esthetic DC (Ivoclar Vivadent), G-CEM LinkForce (GC), Panavia V5 (Kuraray Noritake), Maxcem Elite Chroma (Kerr), and three flowable composites: G-ænial Universal Flo (GC), Herculite XRV Ultra Flow (Kerr), Vertise Flow (Kerr), and one preheated composite: Enamel Plus HRI (Micerium) luted to the prepared occlusal surfaces of the teeth with total-etch, self-etch, and self-adhesive protocols. Then samples were thermocyled (5,000 cycles, 5–55°C, dwell time 20 s). SBS test was performed in a universal testing machine (at 0.5 mm/min). Failure modes were examined under a stereomicroscope at ×25 magnification. Data were analyzed using Kruskal–Wallis and Dunn–Bonferroni tests ( α = 0.05). Results: There were statistically significant differences among material types ( P < .05). Highest SBS values found in G-ænial Universal Flo (15.43 ± 5.67), and the lowest values obtained in Maxcem Elite Choroma (SA) (1.25 ± 1.47). There were no significant differences between self-etch (Panavia V5, Maxcem Elite Choroma [SE]) and self-adhesive (Maxcem Elite Choroma [SA], Vertise Flow) protocols ( P > .05). Conclusion: Flowable composites can be alternatives to resin cements when bonded with total-etch procedures. Bond strength of self-etch and self-adhesive applications is still to be developed.

“…Then, the third tested hypothesis that the filler content and the pre-heating would have influence on the bond strength to the enamel was rejected. However, other studies did find differences in the bond strength between pre-heated and non-heated conventional composites and dentin (19). In this study, it was chosen to use enamel as a substrate because it is more homogeneous than dentin and also because it allows to test the bond strength after the passage of light through the ceramic veneer and resin material.…”

The aim of this study was to evaluate of pre-heating, filler contents and ceramic thickness on film thickness, microshear bond strength, degree of conversion and color change on ceramic veneers. Two experimental composites were prepared (Bis-GMA/UDMA/BisEMA/ TEGDMA), with different amounts of filler (65% or 50%wt) simulating a conventional and a flowable composite. The flowable (F) was used at room temperature and, the conventional either at room temperature (C) or pre-heated (CPH). Disk-shaped ceramics with different thickness (0.4 mm, 0.8 mm, 1.5 mm) were prepared. The film thickness was evaluated according to the ISO 4049 (n=10). The microshear bond strength (n=10) was evaluated in enamel using tubing specimens light-cured through the ceramic veneer. The degree of conversion was evaluated using Raman spectroscopy. The color change of the ceramic restorations (n=10) was evaluated by spectrophotometry. The results were submitted to 2-way ANOVA and Tukey’s post hoc test (a=5%). For the film thickness 1-way ANOVA was used (a=5%). The C presented the thicker film thickness; the CPH produced a similar film thickness in comparison to the F. All composites showed similar microshear bond strength. The degree of conversion of the F was higher than the C and CPH. The degree of conversion of the composites photo-activated through a 0.4 mm was higher than the composites photo-activated through thicker ceramics. The C showed the highest color change, while the CPH showed similar color change to the F. In conclusion, pre-heated conventional composites seem to be a potential alternative to lute ceramic veneers such as the flowable composites.

“…Dessa forma, o pré-aquecimento de resina composta antes da fotopolimerização teve muitas vantagens potenciais, como o aumento o grau de conversão de monômero e aumento da dureza da superfície. Além disso, estudos anteriores mostraram que o procedimento de pré-aquecimento aumentou o fluxo e melhorou a adaptação da resina nas paredes da cavidade e, portanto, microinfiltração potencialmente reduzida (Demirbuga et al, 2016). Todavia, Salgado et al (2010), enfatizou que em condições isotérmicas o pré-aquecimento de composto (60Cº) é capaz de aumentar a conversão de monômero, conforme a mobilidade molecular é aumentada e a frequência de colisão de espécies reativas é aumentada, tendo assim melhores propriedades mecânicas.…”

Devido ao grande apelo estético com o decorrer dos anos associado há técnicas minimamente invasivas, a odontologia contemporânea aposta em materiais com ótimas características estéticas e mecânicas, dessa forma os cirurgiões dentistas buscam apostar no uso do pré-aquecimento das resinas compostas como material cimentante para restaurações indiretas, visto que suas propriedades ópticas e mecânicas propõem uma melhor estética e uma melhor adaptação marginal em comparação aos cimentos resinosos. O objetivo deste trabalho é revisar a literatura a cerca das características ópticas e mecânicas dos diferentes materiais utilizados como agente cimentantes em restaurações indiretas, enfatizando a estabilidade de cor ao longo prazo, adaptação marginal, toxicidade, grau de conversão dos monômeros e praticidade clínica. Para tanto, foi realizada uma busca eletrônica na base de dados Sistema Online de Busca e Análise de Literatura Médica (PubMed), utilizando os seguintes descritores em inglês: thermoactivated resin, temperature e dental veneers, cadastrados no Mesh (Medical Subject Headings) combinado entre si pelo operador boleano “AND”. Após a delimitação de 10 anos para a busca, foram encontrados 50 artigos. Destes, foram selecionados 13 estudos, com base na leitura de títulos e resumos. Em suma, as resinas pré-aquecidas apresentam ótimas características mecânicas e ópticas, no entanto cabe ao cirurgião-dentista escolher qual técnica é mais viável em sua pratica clínica.
