Resumo
Introdução: Os materiais híbridos polímero-cerâmica são um novo tipo de material maquinável CAD/CAM. Eles combinam as vantagens do polímero e da cerâmica. Comparados com materiais de alto módulo de elasticidade, como zircônia e alumina, os materiais híbridos polímero-cerâmica apresentam menor concentração de tensão na estrutura dentária e na interface de união. Objetivos: Avaliar os protocolos de cimentação viáveis para as cerâmicas híbridas por meio de uma revisão de escopo. Métodos: A presente revisão de escopo foi baseada nos critérios do PRISMA, no qual foi realizado uma busca eletrônica em sete bases de dados: Web of Science, Embase, PubMed, Clinical Trials, Scopus, Cochrane, Periódicos da Capes. Foram usados os seguintes descritores: ‘cerâmica híbrida’, ‘protocolo de tratamento de superfície’ e qual o ‘teste de união’. Os artigos duplicados e os estudos que não atenderam aos critérios de inclusão baseados nos descritores mencionados foram excluídos. Os artigos foram analisados e selecionados por meio da plataforma Rayyan. Resultados: Dos 158 artigos identificados, 22 estudos foram incluídos. Os materiais utilizados pelos autores foram as cerâmicas híbridas: Vita Enamic, Lava Ultimate, Cerasmart, Shofu Block, ILc Epricord e Crystal Ultra. Os diferentes tratamentos de superfície abordados nos estudos envolviam o uso de: ácido fluorídrico (HF), jateamento com partículas de óxido de alumínio e/ou sílica, silano, laser e adesivos e primers universais. Microtração, microcisalhamento, tração e cisalhamento foram os ensaios de resistência de união utilizados. Conclusão: Com os estudos que foram incluídos nessa revisão, foi possível observar que a corrosão feita pelo HF continua sendo o padrão ouro para o tratamento de superfícies em cerâmicas híbridas.
Introduction: Polymer-ceramic hybrid materials are a new type of CAD/CAM machinable material. They combine the advantages of polymer and ceramic. Compared to high modulus repair materials such as zirconia and alumina, hybrid polymer-ceramic materials have lower stress concentrations in the tooth structure and bonding interface. Objectives: To evaluate viable cementation protocols through a integrative review and meta-analysis. Methods: This systematic review was based on the PRISMA criteria. An electronic search was carried out in seven databases: Web of Science, Embase, PubMed, Clinical Trials, Scopus, Cochrane, Periodicals of Capes. The following inclusion criteria were used: hybrid ceramics, surface treatment protocol and which union test was presented, discarding duplicate articles and studies that did not meet the inclusion criteria. The articles were analyzed and selected through the RayYan platform. Results: Of the 158 articles identified, 23 studies were included in this review. The materials used by the authors were the hybrid ceramics: Vita ENAMIC, LAVA ULTIMATE, Cerasmart, Shofu Block, and the possible surface treatment protocols presented involving the use of: HF, Alumina blasting with or without silica, Silane, Laser and adhesive. The tests were carried out at different times and concentrations of the analyzed materials. Conclusion: With the studies that were included in this review, it was possible to show that the corrosion made by HF continues to be the gold standard for the treatment of surfaces in hybrid ceramic.
