description In oral implantology, the implant-pillar interface has been a subject of research and constant evolution, mainly from the biomechanical and biological point of view. Objective: To assess the gap in the implant-abutment interface in internal and external hexagonal connection implants by means of scanning electron microscopy (SEM). Materials and Methods: In vitro study in 24 implants (Bionnovation®) divided into two groups (n = 12): internal and external hexagonal connection. For the experiment, straight pillars with 30N of torque were screwed. In turn, 6 implants per group underwent 500,000 cycles of dynamic loading; Subsequently, the space of the pillar implant interface at 3 points of all samples was evaluated by MEB, the means of the results of each specimen were supported in Excel tables and analyzed in the BioEstat 5.3 program. Results: Using a T test for independent samples, with a significance of 95%, a very significant difference was found after the application of the dynamic load in the external hexagon implants (p = 0.0002). In the internal hexagon implants there was also a statistical difference (p = 0.03). Between the external and internal hexagon implants there were very significant differences in the accuracy of the adjustment in the abutment implant interface before and after the application of the dynamic loads (p = <0.0001 and p = 0.0003 respectively). Conclusions: Dynamic loads significantly increased the discrepancy in the implant-abutment connection of the external and internal hexagon implants (p = <0.05); additionally, the gap distance was greater for external hexagon implants in contrast to Internal Hexagon implants before and after dynamic loading, being very significant (p = <0.0003).

Objetivo: Valorar el espacio o “gap” en la interfase implante-pilar en implantes de conexión hexagonal interna y externa por medio de microscopía electrónica de barrido (MEB). Materiales y Métodos: Estudio in vitro en 24 implantes (Bionnovation®) divididos en dos grupos (n=12): conexión hexagonal interna y externa. Para el experimento, se atornillaron pilares rectos con 30N de torque. A su vez 6 implantes por grupo se sometieron a 500000 ciclos de carga dinámica; posteriormente, se evaluó por MEB el espacio de la interfase implante pilar en 3 puntos de todas las muestras, las medias de los resultados de cada espécimen se respaldaron en tablas de Excel y se analizaron en el programa BioEstat 5.3. Resultados: Mediante test T para muestras independientes, con una significancia del 95%, se encontró una diferencia muy significativa luego de la aplicación de la carga dinámica en los implantes de hexágono externo (p= 0.0002). En los implantes de hexágono interno también existió diferencia estadística (p= 0.03). Entre los implantes de hexágono externo e interno existieron diferencias muy significativas en la precisión del ajuste en la interfase implante pilar antes y después de la aplicación de las cargas dinámicas (p= <0.0001 y p= 0.0003 respectivamente). Conclusiones: Las cargas dinámicas aumentaron significativamente la discrepancia en la conexión implante-pilar de los implantes de hexágono externo e interno (p= < 0.05); adicionalmente, la distancia del “gap” fue mayor para los implantes de hexágono externo en contraste con los implantes de Hexágono Interno antes y después de la carga dinámica, siendo muy significativo (p= < 0.0003).Universidad Central del Ecuador2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmltext/htmlhttps://revistadigital.uce.edu.ec/index.php/odontologia/article/view/211810.29166/odontologia.vol22.n1.2020-21-35Odontología; Vol. 22 Núm. 1 (2020): Enero - Junio; 21-351390-996710.29166/odontologia.vol22.n1.2020reponame:Revista Odontologíainstname:Universidad Central del Ecuadorinstacron:UCEspahttps://revistadigital.uce.edu.ec/index.php/odontologia/article/view/2118/2127https://revistadigital.uce.edu.ec/index.php/odontologia/article/view/2118/2188https://revistadigital.uce.edu.ec/index.php/odontologia/article/view/2118/2189Derechos de autor 2020 José Paul Cerda Altamirano, Kleber Vallejohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccess2020-08-20T18:28:34Zoai:revistadigital.uce.edu.ec:article/2118Portal de revistashttps://revistadigital.uce.edu.ec/Universidad públicahttps://uce.edu.ec/**Ecuador*1390-99671390-7468opendoar:02020-08-20T18:28:34Revista Odontología - Universidad Central del Ecuadorfalse
