Resumo: | Objective: The aim of the present study was to compare the fracture strength of endodontically restored teeth with glass-fiber pin and experimental pin of computer-aided design / computer-aided manufacturing (CAD / CAM). Methodology: A total of 20 bovine incisors with sectioned crowns and roots were prepared with 15mm length were randomly divided into two groups (n = 10): G1 - pin fiber glass (control) and G2 - pin machined (experimental). In both groups, the samples had their root canals treated endodontically. The roots were included in acrylic resin, the pins cemented with dual resin cement and subsequently subjected to the compression fracture strength test at a speed of 0.05 mm / min under a 45 ° angle in a universal test machine until the fracture. The values of fracture resistance were submitted to Student's t-test with the SPSS program with a significance level of 5%. Results: According to the tests, the results required strength at fracture was lower in the pre-fabricated custom (48.2kgf) fiber pin group than the group of pins milled by the CAD / CAM system (56.9kgf), however no there was a statistical difference between them (p = 0.26). With a mean SD ± 14.6 for the first and ± 19.0 for the second group. Conclusion: Fiber pins developed by CAD / CAM technology may appear as a viable alternative for intraradicular restorations of endodontically treated elements, since there was no statistical difference in fracture resistance with pre-fabricated pins. |

Metodología:Se preparar um total de 20 bovinos incisivos com coroas e raizes seccionadas com uma longitude de 15 mm e se dividir aleatoriamente nos grupos (n = 10): G1 - pasador de fibra de vidro (controle) e G2 - pasteurizador mecanizado (experimental) . Em ambos os grupos, as muestras tratam endodonciamente o condutor radicular. As raizes se incrementam na resina acrílica, os pinheiros se cimentam com o elemento de resina dupla e, posteriormente, sometieron a resistência à resistência ou a fratura por compressão a uma velocidade de 0,05 mm / min, no ângulo de 45 ° em uma máquina de prueba universal hasta La fractura. Os valores de resistência à fratura são emitidos pelo aluno t-Student com o programa SPSS com um nível de significância de 5%. Resultados:segun os pruebas, os resultados solicitados que a fenda de fratura menor for no grupo de pinheiros de fibra pré-fabricados personalizados (48,2 kgf) que no grupo de pinheiros fresados pelo sistema CAD / CAM (56,9 kgf), sem embargo nenhum diferença estatística entre ellos (p = 0,26). Com uma mídia de ± 14,6 para o primer e ± 19,0 para o segundo grupo. Conclusão: Os pasteurizadores de fibra desarrolados pela tecnologia CAD / CAM aparecem como uma alternativa viável para as restaurações intraradiculares de elementos endodônticos, você não tem um hub diferencial estatístico na resistência a fraturas com pasteurizadores pré-fabricados.Objetivo: O objetivo do presente estudo foi comparar a resistência à fratura de dentes causados pela restauração endodonticamente restaurada com pino de fibra de vidro e pino experimental de fibra de vidro usada pelo método auxiliado por computador / fabricação auxiliada por computador (CAD / CAM). Metodologia: Um total de 20 bovinos incisivos com coroas seccionadas e raízes foram preparadas com 15mm de comprimento foram divididos aleatoriamente em dois grupos (n = 10): G1 - fibra de vidro (controle) G1 - e G2 - fibra de vidro (experimental) . Em ambos os grupos, como peças que tiveram seus condutores radiculares usados endodonticamente.Como as raízes foram incluídas em resina acrílica, os pinos cimentados com cimento resinoso duplo e posteriormente, o teste de resistência à fratura por uma velocidade de 0,05 mm / min, sob uma pressão de 45 ° na máquina de ensaio universal até uma fratura . Os valores de resistência a fratura foram submetidos a teste t-Student com o programa SPSS com nível de significância de 5%. Resultados: acordo com testes, os resultados da força requerida para fratura foi menor no Grupo de pinos de fibra pré-fabricados personalizados (48,2kgf) do que Grupo de pinos fresados pelo sistema CAD / CAM (56,9kgf), porém não mostra diferença estatística entre eles (p = 0,26). Com média de DP ± 14,6 para o primeiro e de ± 19,0 para o segundo grupo. Conclusão: Os pinos de fibra expandida pela tecnologia CAD / CAM podem surgir como alternativa viável para restaurações intrarradiculares de elementos usados endodonticamente, uma vez que não apresentem diferenças estatísticas de resistência à fratura com fragmentos pré-fabricados.Research, Society and Development2020-06-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/490510.33448/rsd-v9i7.4905Research, Society and Development; Vol. 9 No. 7; e884974905Research, Society and Development; Vol. 9 Núm. 7; e884974905Research, Society and Development; v. 9 n. 7; e8849749052525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/4905/4312Copyright (c) 2020 Raquel Adriano Dantas, Letícia Ataíde Delgado, Ana Karina Almeida Rolim, Jéssica Nespolo Martins, Vagner Leme Ortega, Guilherme da Gama Ramosinfo:eu-repo/semantics/openAccessDantas, Raquel AdrianoDelgado, Letícia AtaídeRolim, Ana Karina AlmeidaMartins, Jéssica NespoloOrtega, Vagner LemeRamos, Guilherme da Gama2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4905Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:36.462989Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
