No obstante, com- plicaciones asociadas al dise˜no de la conexi´on implante-pilar pueden comprometer el ´exito del tratamiento. Es por esto que el objetivo de este estudio fue llevar a cabo un an´alisis m´as completo del comportamiento biomec´anico de implantes dentales con conexi´on c´onica y hexagonal, evaluando simult´aneamente la formaci´on de microgap y remodelaci´on ´osea. Se construyeron dos modelos CAD tridimensionales (uno por cada tipo de conexi´on) en el software SolidWorks y se exportaron al software de elementos finitos ABAQUS, donde se llevaron a cabo estudios in silico de la formaci´on de microgap en la interfaz implante-pilar, cuando el implante se somete a cargas c´ıclicas. Para el estudio del proceso de remodelaci´on ´osea, se desarroll´o el algoritmo MED, que fue implementado con la subrutina de usuario UMAT de ABAQUS. El estudio de este proceso se enfoc´o en la regi´on periimplantaria, donde se examinaron la variaci´on en la rigidez y den- sidad del tejido ´oseo como resultado de la remodelaci´on, a trav´es de un tiempo de simulaci´on equivalente a 48 meses. Los resultados mostraron que la conexi´on c´onica ofrece mayor resistencia a la formaci´on de microgap en la interfaz implante-pilar, adem´as de proporcionar una mejor distribuci´on de carga sobre el tejido, que se evidenci´o en una mayor densificaci´on y rigidez tisular a la altura del cuello del implante y, en general, en las regiones de inter´es del estudio, respecto a la conexi´on hexagonal interna. La metodolog´ıa propuesta en este estudio permite la evaluaci´on del comportamiento bio- mec´anico de implantes dentales de acuerdo al dise˜no de la conexi´on implante-pilar, donde los an´alisis de formaci´on de microgap y remodelaci´on ´osea se abordan conjuntamente, a diferencia de estudios previos donde dichos an´alisis se llevan a cabo de manera aislada, des- estimando as´ı factores de riesgo que pueden conducir al fracaso del tratamiento. (Texto tomado de la fuente)Currently, dental implant treatment represents the best alternative for the aesthetic and functional replacement of lost teeth. However, complications associated with the design of the implant-abutment connection can compromise the success of the treatment. Therefore, the objective of this study was to conduct a more comprehensive analysis of the biomecha- nical behavior of dental implants with conical and hexagonal connections, simultaneously evaluating the formation of a microgap and bone remodeling. Two three-dimensional CAD models (one for each type of connection) were constructed using SolidWorks software and exported to the finite element software ABAQUS, where in silico studies of the microgap formation at the implant-abutment interface were conducted under cyclic loading conditions. For the study of the bone remodeling process, the MED algorithm was developed and imple- mented with the user subroutine UMAT in ABAQUS. This study focused on the peri-implant region, examining the variation in tissue stiffness and density resulting from remodeling over a simulation period equivalent to 48 months. The results showed that the conical connection offers greater resistance to the formation of a microgap at the implant-abutment interface, in addition to providing a better load distribu- tion on the tissue. This was evidenced by increased tissue densification and stiffness at the implant neck and, overall, in the regions of interest in the study compared to the internal hexagonal connection. The proposed methodology in this study allows for the evaluation of the biomechanical behavior of dental implants according to the design of the implant-abutment connection. The analyses of microgap formation and bone remodeling are addressed together, unlike previous studies where these analyses are carried out in isolation, thereby disregarding risk factors that may lead to treatment failure.MaestríaMagíster en Ingeniería MecánicaBiomecánica Computacionalxvii, 87 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Ingeniería MecánicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá620 - Ingeniería y operaciones afines::629 - Otras ramas de la ingenieríaImplantes DentalesAtención odontológicaDental careDental ImplantsImplantes dentalesInterfaz implante-pilarConexión cónicaConexión hexagonalBone remodelingMicrogap formationFinite element methodAnálisis comparativo del comportamiento biomecánico de la interfaz implante-pilar en implantes dentales con conexión cónica y hexagonalComparative Analysis of the Biomechanical Behavior of the Implant-Abutment Interface in Dental Implants with Conical and Hexagonal ConnectionsTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TM[Abrahamsson et al., 2009] Abrahamsson, I., Linder, E., and Lang, N.
