Objective: To evaluate the mechanical behavior of stress and microstrain (von Mises yield criterion); in different thicknesses of buccal maxillary bone plates. Methods: The finite element method was used for modeling the maxillary anterior area with three different buccal bone thickness 0.5, 1 and 1.5 mm. An implant-supported restoration was modeled as well, to which a static load of 200 N was applied. Stress and microstrains were obtained in the buccal bone plates at 2, 4 and 6 mm from the alveolar crest towards the apical direction, both in cancellous and cortical bone. Results: Based on the finite element method, it was found that in the thickness of 0.5 mm of buccal bone plate (cortical) with 2 mms height, results showed stress von Mises (31 056 mpa) and displayed microstrains (2 154 µε). As the thickness increased to 1.5 mm with the 2 mm height results stated (22 913 mpa and 1 570 µε). This same trend was observed in the other two heights. Conclusions: The highest values von Mises and micro deformation were found on the crest of the buccal plate with 0.5 mm thickness and decreasing as the volume of cancellous bone increased towards apical direction.La restauración implantosoportada en la zona maxilar anterior debe contar con un mínimo de tabla ósea vestibular que permita una transmisión de esfuerzos sin sobrecarga patológica. Objetivo: Evaluar la distribución de esfuerzos von Mises y microdeformaciones en diferentes espesores de la tabla vestibular en el segmento anterosuperior del maxilar. Métodos: Se utilizó el método de elementos finitos para modelar la zona anterior del maxilar superior con tres diferentes espesores de tabla ósea vestibular (0,5, 1 y 1,5 mm), más una restauración implantosoportada, a la cual se aplicó una carga estática de 200 N (Newtons). Se evaluaron esfuerzos y microdeformaciones de las tablas óseas vestibulares a 2, 4 y 6 mm de la cresta ósea en dirección apical, tanto en el hueso esponjoso como en el cortical. Resultados: De acuerdo al método de elementos finitos se encontró que en el espesor 0,5 mm de tabla ósea vestibular (cortical) y a 2 mm de altura, se presentaron esfuerzos von Mises (31 056 mpa) y microdeformación (2 154 µε), y a medida que el espesor óseo aumentó a 1,5 mm en la altura de 2 mm, se encontró (22 913 mpa y 1 570 µε), esta misma tendencia se observó en las otras dos alturas. Conclusiones: Los mayores valores von Mises y de microdeformación se encontraron en la cresta ósea de la tabla vestibular de 0,5 mm de espesor y disminuyeron a medida que el volumen de hueso esponjoso aumentó en dirección apical.Universidad Nacional Mayor de San Marcos, Facultad de Odontología2018-09-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/odont/article/view/1515010.15381/os.v21i3.15150Odontología Sanmarquina; Vol. 21 No. 3 (2018); 195-203Odontología Sanmarquina; Vol. 21 Núm. 3 (2018); 195-2031609-86171560-9111reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/odont/article/view/15150/13141Derechos de autor 2018 Julio Cesar Escobar Restrepo, Juan David Serna Ceballos, Federico Latorre Correa, Junes Abdul Villarraga Ossahttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/151502018-09-18T12:31:52Z
