RESUMO

Occlusal plane (OP) is one of the essential factors affecting craniofacial morphology and function. The OP not only assists in diagnosing malocclusion but also serves as an important reference for making treatment plans. Patients with different types of malocclusions have different forms of OP. Compared with patients with standard skeletal facial type, the occlusal plane of patients with skeletal class Ⅱ and high angle is steeper, while that of patients with skeletal class Ⅲ and low angle is more even. In orthodontic treatment, adjusting and controlling the OP can promote the normal growth and development of the mandible in most patients with malocclusion during the early stage of growth, while causing favorable rotation of the mandible in some adults with mild-to-moderate malocclusion. For moderate-to-severe malocclusion, the OP rotation by orthodontic-orthognathic treatment can achieve better long-term stability. This article reviews the evolution of the definition of OP and its implications for diagnosing and the guiding treatment of malocclusion.

RESUMO

En la población joven venezolana las maloclusiones representan un importante problema de salud bucal. Resulta útil la aplicación de métodos diagnósticos cefalométricos como el propuesto por Petrovic que permitan identificar el potencial de crecimiento mandibular del paciente como un instrumento para seleccionar la modalidad de tratamiento. El propósito de esta investigación fue identificar los grupos rotacionales y las categorías auxológicas en pacientes venezolanos, de ambos géneros, entre 7 y 10 años, que acudieron a la Facultad de Odontología de la UCV, durante el periodo 2006-2010. Se aplicó el método cefalométrico de Petrovic para la identificación del tipo rotacional y categoría auxológica en las radiografías cefálicas laterales de pacientes sin tratamiento ortopédico ni ortodóncico previo. El tipo rotacional más frecuente fue el P1N, seguido por R2D, R1N y P2D; en ambos géneros el tipo rotacional P1N fue el más frecuente, sin embargo en el género femenino, también se observaron los tipos P2D, R2D y R1N. El grupo rotacional más frecuente fue P1NOB y en segundo lugar R1NOB. Los grupos rotacionales P1NOB y R1NOB fueron los más frecuentes en las niñas y P1NOB en los niños. La determinación del tipo rotacional y la categoría auxológica es una herramienta diagnóstica importante para orientar el plan de tratamiento más acorde según el potencial de crecimiento del paciente...


In the young venezuelan population, malocclusions are an important oral health problem. It is useful the application of cephalometric diagnostic methods as the proposed by Petrovic that allows to identify the mandibular growth potential of the patient as a tool to select the appropriate treatment modality. The aim of this study was to identify the rotational auxologic groups and categories in Venezuelan patients for both genders, age between 7 and 10 years, who had been attended in the Faculty of Dentistry of the Universidad Central of Venezuela, during the period 2006-2010. Was applied Petrovic cephalometric method for identifying the rotational type and auxologic category in the cephalic lateral radiographs of patients without previous orthodontic or orthopedic treatment. The most frequent rotational type was P1N, followed by R2D, R1N and P2D; in both genders P1N rotational type was the most common, however in the female gender, P2D, and R2D and R1N types were also observed. The most frequent rotational group was P1NOB and secondly R1NOB. R1NOB and P1NOB were rotational groups most frequent in girls and in boys was P1NOB. The determination of the rotational type and auxologic category is important to guide the treatment plan according to the patient's growth potential...

RESUMO

El plano oclusal ha sido un elemento importante en cirugía ortognática durante los últimos 20 años. Las investigaciones iniciales demostraron que las características faciales están altamente asociadas a la posición mandibular; siendo así, la rotación del plano oclusal permite una reposición oclusal diferente de la inicial, además una relación facial tanto vertical como anteroposterior favorable en términos de estética y proporciones faciales. Las investigaciones realizadas para cuantificar y caracterizar este movimiento han sido limitadas, pero auspiciosas; se ha determinado que la rotación del plano oclusal es un movimiento estable y versátil, siendo útil en diferente tipos de pacientes. El objetivo de este estudio es identificar las principales características asociadas a la rotación del plano oclusal así como analizar las principales investigaciones al respecto.


Occlusal plane has been an important element in orthognatic surgery during these last 20 years. The primary investigations have shown that facial characteristics are highly associated to mandibular positioning. Thus, occlusal plane rotation allows an acclusal plan different from the initial one, even as vertical and anterior-posterior positioning more favorable en endings of aesthetic. Besides the studies carried through to measure y to characterize these movements are limited, they are favorable. They have demonstrated that occlusal plane rotation versatile y stable, being useful en different types of facial deformities. The meaning of this work are identify the more important characteristic about occlusal plane rotation as well analyze the most cited articles in the literature.
