ABSTRACT: The finite element method was used to analyze the stresses in teeth restored with posts. The variables studied were material and modulus of elasticity of dowel. Methods: the model of the post-restored tooth involved dentin, ligament, cortical and trabecular bone, gingiva, metal-ceramic crown, and gutta-percha. The dowels were made of zirconium, base metal and noble metal casting alloys. The dowel was cemented with resin luting agents. The variable included was modulus of elasticity and Poisson’s ratio. A load of 200 N was applied to the crown an angle of 45 degrees in order to calculate the stress distribution and tensile shear also von misses stresses. Results: showed von Misses stress in dentin: Noble metal alloys 105.1899 N/mm2, base metal alloys 69.86746 N/(mm2) and zirconia 69.06321 N/mm2. Von Misses stress in dowel: Noble metal alloys 210.3797 N/mm2, base metal alloys 349.3373 N/mm2 and zirconia 345.3161 N/mm2. Conclusions: within the limitations of the study, it was found that increasing the elastic modulus of the post l was found to cause decreased dentin stress. |

Métodos: el modelo del diente restaurado con poste está formado por dentina, ligamento, hueso cortical y trabeculado, corona metal-cerámica y gutapercha. El poste fue hecho de zirconia, aleación de metal base y metal noble. El poste fue cementado con cemento resinoso. Las variables incluidas en el modelado fueron módulo de elasticidad y razón de Poisson para todos los componentes del modelo. Se aplicó una carga de 200 N en la corona con una inclinación de 45º para calcular la distribución de los esfuerzos tanto tensiles, compresivos y de Von Mises. Resultados: se muestra el esfuerzo Von Mises en la dentina: aleación de metal noble 105,1899 N/mm2, aleación de metal base 69,86746 N/mm2 y zirconia 69,06321 N/mm2. El esfuerzo Von Mises en el perno: aleación de metal noble 210,3797 N/mm2, aleación de metal base 349,3373 N/mm2 y zirconia 345,3161 N/mm2. Conclusiones: con las limitantes de este estudio, se encontró que el incremento en el módulo de elasticidad de los postes causa disminución de los esfuerzos en la dentina.application/pdfspaUniversidad de Antioquia, Facultad de OdontologíaMedellín, Colombiahttps://creativecommons.org/licenses/by-nc-sa/4.0/https://creativecommons.org/licenses/by-nc-sa/2.5/co/Atribución-NoComercial-CompartirIgual 2.5 Colombia (CC BY-NC-SA 2.5 CO)info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Técnica de perno-muñónAnálisis elementos finitosAleaciones de cerámica y metalEndodonciaPost and core techniqueFinite element analysisMetal ceramic alloysEndodonticsDistribución de los esfuerzos en un incisivo central superior restaurado con diferentes postesStress distribution of an upper central incisor restored with different postsArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionRev Fac Odontol Univ Antioq5914919Revista Facultad de Odontología Universidad de AntioquiaPublicationORIGINALSanchezHugo_2007_DistribucionIncisivoPostes.pdfSanchezHugo_2007_DistribucionIncisivoPostes.pdfArtículo de investigaciónapplication/pdf507653https://bibliotecadigital.udea.edu.co/bitstreams/fb7f9acf-02b7-40f0-b7da-a5d557eeedcb/download257a5746d8d088680fe2316132683098MD51trueAnonymousREADCC-LICENSElicense_urllicense_urltext/plain;
