Abstract(s)
Introdução | Os dados sobre o comportamento de cerâmicas de matriz resinosa para materiais CAD-CAM atuais são limitados.
Objetivos | É propósito desta revisão narrativa de literatura esclarecer se as restaurações indiretas realizadas com blocos de resina composta/polímeros híbridos em CAD-CAM possuem propriedades mecânicas semelhantes às realizadas em cerâmica.
Metodologia | A pesquisa bibliográfica realizou-se na base de dados de publicações científicas Medline, Science Direct e B-on, publicações em inglês, português ou francês, entre 2010 e 2023 obtiveram-se 96 artigos, dos quais 14 apresentam pertinência para o esclarecimento da questão de investigação que sustenta esta revisão.
Conclusões | Não há consenso quanto à escolha do material mais indicado para a produção de restaurações indiretas. Contudo, os inlays compostos por resina nano cerâmica têm demonstrado oferecer resistência à fratura significativamente maior.
Introduction | Data on the behavior of resin matrix ceramics for current CAD CAM materials is limited. Objectives | It is the purpose of this narrative literature review to clarify whether indirect restorations performed with blocks of composite resin/hybrid polymers in CAD CAM have mechanical properties similar to those performed in ceramics. Methodology | The bibliographic search was carried out in the database of scientific publications Medline, Science Direct and B-on, publications in English, Portuguese or French, in the last 10 years (2012-2023): 96 articles were obtained, of which 14 present pertinences for clarifying the research question that supports this review. Conclusions | There is no consensus regarding the choice of the most suitable material for the production of indirect restorations. However, inlays composed of nanoceramic resin have been shown to offer significantly greater resistance to fracture.
