| description | Factors such as the reduction of existing dental tissue after an endodontic treatment, the design of the carving and the restorative material condition the success of rehabilitation. Objective: To evaluate the compressive strength and failure mode against axial forces of endodontics upper premolars rehabilitated with lithium disilicate crowns. Methodology: thirty healthy upper premolars, which will be randomly classified into three groups, one control group and two experimental ones, all the teeth will be endodontically treated and rehabilitated with lithium disilicate crowns The samples will be subjected to 5000 before being subjected to axial compressive forces with the universal force machine. Results: the compressive strength values are 675.7 N for the control group (D), 1118.5 N for the glass fiber post and crown (C), and 1403.9 N for the endocrowns group (E). The values of endocrowns, to the statistical ANOVA test is of p = 0.000, which indicates that there is a statistically significant difference, to the analysis by pairs, by Tukey’s Post Hoc test, (D) and (C) p = 0.020, (D) with (E) p = 0.000. The Student’s T-test shows Endocrown is the one that most resists compression. Regarding the failure mode, when performing the Chi-square test we have a p = 0.301 between the experimental groups, that is to say that, there is no statistically significant difference of the results obtained in terms of the failure modes. Conclusion: the endocrown is the recommended procedure. |

Objetivo: Evaluar la resistencia compresiva y el modo de falla frente a fuerzas axiales de premolares superiores endodonciados, rehabilitados con coronas de disilicato de litio. Metodología: treinta premolares superiores sanos, aleatoriamente serán clasificados en tres grupos, un grupo control y dos experimentales. Todos los dientes fueron endodonciados y rehabilitados con coronas de disilicato de litio. Las muestras serán sometidas a 5000 ciclos antes de someterse a fuerzas compresivas axiales con la máquina de fuerzas universales. Resultados: Los valores de la resistencia compresiva son para el grupo control (D) 675,7 N, para los grupos experimentales, grupo perno corona (C) 1118,5 N y grupo endocorona (E) 1403,9 N, mediante la prueba Post Hoc de Tukey, Diente (D) y Perno Corona (C) p= 0.020, Diente (D) con Endocorona (E) el p= 0.000, en la relación Perno Corona (C) con Endocorona (E) p = 0.171 > 0.05 es la única relación donde no existe una diferencia significativa entre estas dos variables. La prueba t de Student indica que el tratamiento de Endocorona es la que más resiste a la compresión. En cuanto al modo de fallo, al realizar la prueba de Chi-cuadrado se tiene un p= 0.301. Conclusión: se determina que la endocorona es el procedimiento recomendado.Universidad Central del Ecuador2022-01-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistadigital.uce.edu.ec/index.php/odontologia/article/view/356110.29166/odontologia.vol24.n1.2022-e3561Odontología; Vol. 24 Núm. 1 (2022): Enero - Junio; e35611390-9967reponame:Revista Odontologíainstname:Universidad Central del Ecuadorinstacron:UCEspahttps://revistadigital.uce.edu.ec/index.php/odontologia/article/view/3561/4411Derechos de autor 2022 Grace Anabel Balladares Araujo, Julio Humberto Fernández Freire, Daniela Cristina Dávila Gallardohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccess2022-02-04T11:50:11Zoai:revistadigital.uce.edu.ec:article/3561Portal de revistashttps://revistadigital.uce.edu.ec/Universidad públicahttps://uce.edu.ec/**Ecuador*1390-99671390-7468opendoar:02022-02-04T11:50:11Revista Odontología - Universidad Central del Ecuadorfalse |
