Abstract
Actualmente sigue existiendo un amplio marco de desconocimiento rodeando la maloclusión esquelética de clase III. Se conoce la existencia de diversos subgrupos de fenotipos de las clases III, pero siguen siendo pocos los estudios que investigan esta diferenciación. En población española sigue sin existir un claro marco de caracterización de los distintos subtipos. La identificación y descripción detallada de subtipos fenotípicos en nuestra población diana, permitirá obtener criterios objetivos para el desarrollo de estudios futuros, analizando respuestas en el tratamiento y analizando factores etiológicos y diferenciadores de cada sub-fenotipo. Objetivos: El objetivo principal de este estudio es clasificar la maloclusión esquelética de clase III en diversos subgrupos dependiendo de las características fenotípicas que se determinen en la medición cefalométrica de un grupo de sujetos con maloclusión de clase III y de origen español. Como objetivos secundarios se pretende conocer la existencia de diferencias entre los diversos sub-fenotipos en diferentes poblaciones, establecer un modelo de cluster ajustados a la población española con maloclusión esquelética de clase III, determinar la prevalencia de cada sub-fenotipo y la prevalencia según el género, y definir un modelo de cluster en población española de clase III esquelética en base a medidas proporcionales...
There is still a large framework of ignorance surrounding class III skeletal malocclusion today. Several subgroups of class III phenotypes are known to exist, but there are still few studies investigating this differentiation. In the Spanish population there is still no clear framework to characterize the different subtypes. The identification and detailed description of phenotypic subtypes in our target population, will allow to obtain objective criteria for the development of future studies, analyzing responses in the treatment and analyzing etiological and differentiating factors of each subphenotype. Objectives: The main objective of this study is to classify class III skeletal malocclusion into different subgroups depending on the phenotypic characteristics determined in the cephalometric measurement of a group of subjects with class III malocclusion and of Spanish origin. As secondary objectives, we intend to know the existence of differences between the different subphenotypes in different populations, to establish a cluster model adjusted to the Spanish population with class III skeletal malocclusion, to determine the prevalence of each subphenotype and the prevalence according to gender, and to define a cluster model in the Spanish population with class III skeletal malocclusion based on proportional measures...
