Resumo: | Background: Adhesive cementation is essential for the longevity of indirect esthetic restorations. However, polymerization shrinkage of resin cement generates stress, which may cause failures in the tooth–restoration interface. So, understanding of the biomechanics of resin cement is important for predicting the clinical behavior of an esthetic indirect restoration. Aims: To analyze the stresses generated during polymerization shrinkage of self-curing resin cement in ceramic and in indirect resin (IR) restorations, using the finite-element method (FEM). Settings and Design: Numerical study using the finite-element analysis. Materials and Methods: A three-dimensional (3D) model of a second molar restored with ceramic or IR onlay restoration was designed. The polymerization shrinkage of self-curing resin cement was simulated in FEM software using an analogy between the thermal stress and the resulting contraction of the resin cement. The localization and values of tensile stresses in the dental structure, cement, and adhesive layer were identified. Results: The location and value of the tensile stresses were similar for the two restorative materials. High tensile stresses were identified in the axiopulpal wall and angles of the tooth preparation, with the major stresses found in the cement located in the axiopulpal wall. Conclusions: The high stresses values and their concentration in the angles of the prepared tooth emphasize the importance of round angles and the use of cements with lower rates of shrinkage. |

Entretanto, a contração de polimerização do cimento resinoso gera tensões, que podem causar falhas na interface dente-restauração. Assim, o entendimento da biomecânica do cimento resinoso é importante para prever o comportamento clínico de uma restauração estética indireta. Objetivos: analisar as tensões geradas durante a contração de polimerização do cimento resinoso autopolimerizável em restaurações cerâmicas e de resina indireta (IR), utilizando o método dos elementos finitos (MEF). Configurações e projeto: estudo numérico utilizando análise de elementos finitos. Materiais e métodos: um modelo tridimensional (3D) de um segundo molar restaurado com restauração cerâmica ou IR onlay foi projetado. A contração de polimerização do cimento resinoso autopolimerizável foi simulada no software FEM utilizando uma analogia entre a tensão térmica e a contração resultante do cimento resinoso. A localização e os valores das tensões de tração na estrutura dentária, cimento e camada adesiva foram identificados. Resultados: a localização e o valor das tensões de tração foram semelhantes para os dois materiais restauradores. Altas tensões de tração foram identificadas na parede axiopulpar e nos ângulos do preparo dentário, sendo as maiores tensões encontradas no cimento localizadas na parede axiopulpar. Conclusões: os elevados valores de tensões e sua concentração nos ângulos do dente preparado enfatizam a importância dos ângulos arredondados e da utilização de cimentos com menores taxas de retração.engUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA ESTRUTURASIndian journal of dental researchBiomecânicaCimentos dentáriosMétodo dos elementos finitosResinas dentáriasAdesivos dentináriosAdhesionBiomechanicsDental cementFinite-element methodPolymerization shrinkageAnalysis of stresses during the polymerization shrinkage of self-curing resin cement in indirect restorations: a finite-element studyAnálise de tensões durante a contração de polimerização de cimento resinoso autopolimerizável em restaurações indiretas: estudo de elementos finitosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://journals.lww.com/ijdr/fulltext/2014/25060/analysis_of_stresses_during_the_polymerization.14.aspxTulimar Machado Pereira CornacchiaGuilherme Costa Carvalho SilvaClaudia Silami de MagalhãesAllyson Nogueira MoreiraEstevam Barbosa de Las Casasapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
