Resumo: | AbstractIntroduction The biomechanical behavior of endodontically treated teeth depending on the selected restorative material and tooth situation to be restored.Objective To analyze by the two-dimensional finite element method the biomechanical behavior of different diameters in intraradicular posts and teeth with coronal remaining of 2mm.Material and method Six models were made with three types of posts, as follows: Glass fiber post, carbon fiber post, and cast metal post, both with diameter # 1 (1.1 mm in diameter) and # 2 (1.3 mm of diameter). The modeling was performed using the Rhinoceros 4.0 program. The FEMAP 10.2 and NEiNastran 9.2 programs were used to develop finite element models. The loading used was 100N for axial and oblique forces. The results were visualized using the von Mises stress map. The statistical analysis was made using analysis of variance (ANOVA) and Tukey post-test, with a significance level of 5%.Result The oblique loading stress values were higher than the axial loading (p<0.001) for both situations. The glass fiber post showed the lowest concentrations of stress on both loads (p<0.001). The carbon fiber post presented significant difference compared to the cast metal post, only in the oblique load (p=0.007). The diameter did not increase the stress of the evaluated posts (p=0.302).Conclusion The fiber posts were more favorable for restoration of endodontically treated teeth; the increase of diameter did not influence the increase of tension; the oblique load was more harmful for both posts and tooth structure. |

A modelagem foi realizada através do programa Rhinoceros 4.0, e em seguida nos programas FEMAP 10.2 e NeiNastran 9.2 para desenvolvimento d os modelos de elementos finitos. Nos carregamentos foram utilizadas forças de 100N axial e oblíquo. Os resultados foram visualizados pelo mapa de tensão von Mises, e pela análise de variância (ANOVA) e pós-teste Tukey, com nível de significância à 5%.Resultado O carregamento oblíquo apresentou maiores valores de tensões (p<0,001). O pino de fibra de vidro apresentou menores concentrações de tensões em ambos os carregamentos (p<0,001). O pino de fibra de carbono apresentou diferença significativa em relação ao núcleo metálico somente no carregamento oblíquo (p=0,007). O diâmetro não influenciou para o aumento de tensões dos retentores avaliados (p=0,302).Conclusão Os pinos de fibras são mais favoráveis para restaurações de dentes tratados endodonticamente; O aumento do diâmetro não influenciou no aumento de tensões; A carga oblíqua é mais prejudicial à tanto para o retentor quanto para a estrutura dentária.Universidade Estadual Paulista Faculdade de Odontologia de AraçatubaUniversidade Federal de Alfenas Faculdade de OdontologiaUniversidade Estadual Paulista Faculdade de Odontologia de AraçatubaUniversidade Estadual Paulista Júlio de Mesquita FilhoUniversidade Estadual Paulista (Unesp)Universidade Federal de Alfenas Faculdade de OdontologiaLemos, Cleidiel Aparecido AraujoAlmeida, Daniel Augusto De FariaBatista, Victor Eduardo De SouzaMello, Carol CantieriVerri, Fellippo RamosPellizzer, Eduardo PizaMazaro, José Vitor Quinelli2018-11-12T17:27:08Z2018-11-12T17:27:08Z2016-06-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article171-176application/pdfhttp://dx.doi.org/10.1590/1807-2577.21215Revista de Odontologia da UNESP.
