Abstract
La oclusión y maloclusión en Ortodoncia fueron descritas en 1899 en la clasificación de Angle mediante la relación mesiodistal de las coronas de los primeros molares permanentes. Esta clasificación se suplementó en 1972 con las Seis Llaves de la Oclusión Ideal de Andrews, lo que supuso la primera orientación para los valores de angulación y torque en la práctica clínica. JUSTIFICACIÓN Desde que Andrews preconizase los cánones de oclusión en forma de las Seis Llaves de la Oclusión Ideal, otros autores han estimado la angulación e inclinación de la corona en pacientes con oclusión ideal para conocer si existían diferencias entre ellas. Estos valores tienen repercusión en la estética de la sonrisa y en la función. HIPÓTESIS No existirán diferencias estadísticamente significativas en los valores de angulación e inclinación propuestos por Andrews y los de los pacientes con oclusión ideal no tratados con ortodoncia de esta investigación. OBJETIVOS El objetivo principal fue verificar si se cumplen las Seis Llaves de la Oclusión Ideal para una muestra de pacientes españoles con oclusión ideal no tratados ortodóncicamente...
Occlusion and malocclusion in Orthodontics were presented in detail in 1899 in Angle’s classification using the mesiodistal ratio of the crowns of the first permanent molars. This classification was supplemented in 1972 with Andrews' Six Keys to Optimal Occlusion, representing the first guidance for angulation and inclination values in clinical practice.JUSTIFICATION Ever since Andrews recommended his occlusion guidelines in the form of his Six Keys to Optimal Occlusion, other authors have estimated the crown angulation and inclination in patients with optimal occlusion to see if there are any differences between them. These values affect smile aesthetics and function. HYPOTHESIS No statistically significant differences will be found between the angulation and inclination values proposed by Andrews and values obtained from patients that have optimal occlusion and have not received orthodontic treatment. OBJECTIVES The main objective was to check whether a sample of Spanish patients that have optimal occlusion and have not received orthodontic treatment meet the Six Keys to Optimal Occlusion...
