Abstract(s)
A cimentação é considerada o procedimento mais crítico das restaurações indiretas e o cimento utilizado é considerado o elo mais fraco da estrutura formada pela associação peça protética-cimento-dente. A comparação entre resinas compostas pré-aquecidas e cimento de resina é crucial no contexto dos procedimentos odontológicos. Os compósitos pré-aquecidos representam uma tendência crescente para a cimentação adesiva de restaurações indiretas. Por outro lado, o cimento de resina é tradicionalmente usado para a cimentação de restaurações indiretas. Este cimento proporciona uma ligação confiável entre a restauração e a estrutura dentária subjacente.
Objetivo: Avaliar e comparar as resinas compostas pré-aquecidas e o cimento de resina utilizados como agentes cimentantes em restaurações indiretas, enfatizando a estabilidade de cor a longo prazo, adaptação marginal, toxicidade, grau de conversão dos monômeros e eficácia clínica.
Materiais e métodos: Para tal, foi realizada uma busca eletrônica nas bases de dados PubMed, Scopus, Scielo e Medline utilizando as seguintes palavras-chave em inglês: thermoactivated composite resin, temperature, resin cement, indirect restorations, cadastrados no MeSH (Medical Subject Headings) combinados entre si pelo operador booleano “AND”. Os critérios de inclusão definidos para a seleção dos artigos foram: artigos publicados em português, inglês, italiano, espanhol e francês; artigos na íntegra que retratassem a temática referente à revisão integrativa e artigos publicados e indexados nos referidos bancos de dados nos últimos dez anos.
Resultados: Os cimentos resinosos fotopolimerizáveis são os que mais se adequam à cimentação de restaurações indiretas, pela estabilidade de cor que apresentam e pelo seu maior tempo de trabalho, relativamente aos cimentos de polimerização dupla ou aos cimentos quimicamente ativados. De forma a uniformizar procedimentos de cimentação, é extremamente vantajoso poder utilizar-se um único material, com capacidade para cimentar com qualidade e longevidade diversos materiais restauradores.
Conclusão: Tanto as resinas compostas pré-aquecidas como os cimentos resinosos são boas alternativas para cimentar restaurações indiretas em cerâmica.
Cementation is considered the most critical procedure in indirect restorations, and the cement used is regarded as the weakest link in the structure formed by the prosthetic piece-cement-tooth association. The comparison between preheated composite resins and resin cement is crucial in the context of dental procedures. Preheated composites represent a growing trend in adhesive cementation of indirect restorations. On the other hand, resin cement is traditionally used for the cementation of indirect restorations. This cement provides a reliable bond between the restoration and the underlying dental structure. Objective: To evaluate and compare preheated composite resins and resin cement used as cementing agents in indirect restorations, emphasizing long-term color stability, marginal adaptation, toxicity, monomer conversion rate, and clinical effectiveness. Materials and methods: For this purpose, an electronic search was carried out in the PubMed, Scopus, Scielo, and Medline databases using the following keywords in English: thermoactivated composite resin, temperature, resin cement, indirect restorations, registered in MeSH (Medical Subject Headings) combined using the boolean operator “AND”. The inclusion criteria for article selection were: articles published in Portuguese, English, Italian, Spanish, and French; full articles addressing the theme of the integrative review; and articles published and indexed in the referenced databases within the last ten years. Results: Light-cured resin cements are the most suitable for cementation of indirect restorations due to their color stability and longer working time compared to dual-polymerized or chemically activated cements. In order to standardize cementation procedures, it is highly advantageous to use a single material capable of ensuring quality cementation and longevity for various restorative materials. Conclusion: Both preheated composite resins and resin cements are good alternatives for cementing indirect ceramic restorations.
