description |
Maxillary expansion is an orthodontic procedure that is used to treat the transverse maxillary deficiency. This procedure increases the transversal measurement of the maxilla taking advantage of the presence of the fibrous tissue that joins the two horizontal portions of the palate, known as midpalatal suture. To overcome some adverse effects that are generated with this treatment, or to make changes in the technique, it is necessary to understand the behavior of the suture and the surrounding tissues. Consequently, this work seeks to evaluate the midpalatal suture formation processes, and its response to the presence of external loads such as those generated during the expansion, from both an experimental and computational perspective. Therefore, the project was developed by means of an experimental model, a computational mechanobiological model, a biomechanical computational model in 2D and a biomechanical computational model in 3D. For the development of the experimental model, an in vivo procedure was standardized to observe the effect of tensile loads on cellular activity inside the suture and on the expressions of some molecular factors located at the bone–suture–bone interface. The procedure can be used as a reference for future research on this suture. With respect to the mechanobiological model, the mathematical model proposed achieves to reproduce the cellular migration phenomena that are carried out as a consequence of the expansion loads application and simulates the remodeling processes that occur at the bone margins, replicating the initial states of the midpalatal suture morphology in humans and generating more complex interdigitation patterns in expanded sutures. In relation to the biomechanical models, it was possible to evaluate the influence of certain parameters, such as the interdigitation degree and the anchorage type used, in the structural behavior of the oral cavity when it is subjected to an maxillary expansion treatment. The experimentally findings and the biomechanical models derived from this research can be used by dentists and clinicians to understand some events that happen into the oral cavity during the period of treatment. On the other hand, the mechanobiological model could be the first approach looking for reproduce the molecular and cellular interaction into the midpalatal suture, when a maxillary expansion is applied, by a combination of a basic chemotaxis model and a reaction–diffusion model. |

Este procedimiento incrementa la medida transversal del maxilar aprovechando la presencia del tejido fibroso que une las dos porciones horizontales del paladar, conocido como sutura medial palatina. Para superar algunos efectos adversos que se generan con este tratamiento, o realizar cambios en la técnica, es necesario entender el comportamiento de la sutura y de los tejidos que la rodean. En consecuencia, este trabajo busca evaluar los procesos de formación de la sutura medial palatina, y su respuesta a la presencia de cargas externas como aquellas generadas durante la expansión, desde una perspectiva tanto experimental como computacional. Por lo tanto, el proyecto fue desarrollado por medio de un modelo experimental, un modelo computacional mecanobiológico, un modelo computacional biomecánico en 2D y un modelo computacional biomecánico en 3D. Para el desarrollo del modelo experimental se estandarizó un procedimiento in vivo que permitió observar el efecto de las cargas de tensión sobre la actividad celular al interior de la sutura y sobre las expresiones de algunos factores moleculares localizados en la interfaz hueso–sutura–hueso. El procedimiento podrá ser utilizado como referencia para la realización de futuras investigaciones en esta sutura. Con respecto al modelo mecanobiológico, el modelo matemático planteado logra reproducir los fenómenos de migración celular que se producen como consecuencia de la aplicación de cargas de expansión y simula los procesos de remodelado que acontecen en los márgenes óseos, replicando los estados iniciales de la morfología de la sutura medial palatina en humanos y generando patrones de interdigitación de mayor complejidad en suturas expandidas. En relación a los modelos biomecánicos, fue posible evaluar la influencia de ciertos parámetros, como el grado de interdigitación y el tipo de anclaje empleado, en el comportamiento estructural de la cavidad oral cuando es sometida a un tratamiento de expansión del maxilar. Los hallazgos experimentales y los modelos biomecánicos derivados de esta investigación pueden ser utilizados por odontólogos y clínicos para comprender algunos eventos que ocurren en la cavidad oral durante el período del tratamiento. Por otro lado, el modelo mecanobiológico podría ser el primer enfoque que busca reproducir la interacción molecular y celular en la sutura medial palatina, cuando se aplica una expansión del maxilar, mediante una combinación de un modelo de quimiotaxis básico y un modelo de reacción–difusión.Doctoradoapplication/pdfspaUniversidad Nacional de Colombia Sede Bogotá Facultad de IngenieríaFacultad de IngenieríaUniversidad Nacional de Colombia Sede Bogotá Facultad de Ingeniería Departamento de Ingeniería Mecánica y Mecatrónica Ingeniería MecatrónicaIngeniería MecatrónicaUniversidad Nacional de Colombia Sede Bogotá Facultad de Ingeniería Departamento de Ingeniería Mecánica y Mecatrónica Ingeniería Mecánica Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Mecatrónica Ingeniería MecánicaIngeniería Mecánica62 Ingeniería y operaciones afines / EngineeringGuerrero Vargas, José Alejandro (2019) Biomechanical and mechanobiological model of the midpalatal suture formation process, by computational simulation.
