Objetive. The purpose of this study was to know and determine the microstrain and stress distribution in bucal bone, regenerated and rehabilitated with an implant using the finite element analysis (FEA). Methods. The thickness of maxillar bone modeling with bucal bone regeneration was 1.5 mm with a dental implant in position of the central incisor (Cancellous, cortical and regenerated bone, implant and prosthetic components). The variables were the modulus of elasticity and Poisson`s ratio for all the components in the model. A load of 200 N was applied to the palatal surface of the crown in order to calculate the microstrain stress distribution of the bone. Results. The maximum equivalent stress values of von Mises were found in the cortical bone (44.89 MPa) surrounding the neck of the implant and concentrated on the first four implant threads adjacent to the native bone in the palatal ...

For an implant-supported restoration of the maxillary anterior area; the buccal bone plate should have a minimum thickness to ensure an optimal and predictable behavior of soft tissue. 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 hei...

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 es...
