Abstract
El tratamiento de las maloclusiones de clase III en la población infantil es uno de los mayores retos en ortopedia dentofacial debido a la alta incidencia en pacientes ortodóncicos, al empeoramiento de las características faciales y oclusales con la edad, y a la incertidumbre de obtener resultados estables que se mantengan en el tiempo.
Actualmente, la máscara facial, con o sin expansión maxilar previa, es uno de los aparatos más utilizados, y la literatura sugiere que, los efectos del tratamiento con máscara facial son una combinación de cambios esqueléticos y dentales en maxilar y mandíbula.
No existen muchos estudios longitudinales sobre el crecimiento en clases III, ni sobre el tratamiento precoz con resultados a largo plazo. A día de hoy no conocemos con certeza el porcentaje de recidivas que indiquen si los pacientes mantienen tras finalizar el crecimiento activo las relaciones dentarias con las que terminaron el tratamiento de ortodoncia, y por ello, nos hemos propuesto valorar la estabilidad a largo plazo del tratamiento temprano de los sujetos de clase III.
OBJETIVO: El objetivo general es determinar si a nivel dentario, el tratamiento temprano de la maloclusión de clase III es estable a largo plazo y una vez finalizado el crecimiento; y a la vez comparar los cambios en las arcadas dentarias tras una fase de retención de 10 años del grupo tratado de clase lll con un grupo tratado de clase l...
Class III treatment in young patients is one of the greatest challenges in orthodontics due to high frequency, worsening of facial and occlusal characteristics with age, and the uncertainty of obtaining stable results over time and after growth is completed. Most common orthopedic treatment of class III consists of maxillary expansion followed by protraction of the maxilla with a chincup or a facemask. The effects of this treatment are a combination of dental and skeletal changes both in the maxilla and the mandible. There is no sufficient data on growth in class III subjects, and there are very few studies on long-term results of early treatment. The percentage of relapse remains uncertain, this is why we believe in the need to study the long-term effects of early treatment in class III malocclusion and determine its stability. OBJECTIVE: The aim of this study is to determine if early class III treatment is stable in the long term, and if therefore patients maintain the same occlusal relationships as at the end of treatment. And also compare these dental changes with a class I control group with at least 10 years of retention...
