ABSTRACT

Objetivos: Relacionar el plano oclusal con la discrepancia posterior aplicando el cefalograma de kim y el análisis del marco dental del Dr. Sato. Material y métodos: El presente estudio se efectuó en radiografías cefalometricas de 80 pacientes entre las edades de 15 a 25 años de ambos sexos, distribuidas en 4 grupos cuyo tamaño fue determinado por formula: 20 radiografías laterales de pacientes con maloclusión clase II ángulo bajo, 20 con ángulo alto, 20 radiografías de pacientes para maloclusión clase III ángulo bajo y 20 con ángulo alto. La técnica de recolección de datos fue la observación radiográfica, la cual se operatizo a través de su respectivo instrumento. El análisis de los datos se realizó mediante la estadística descriptiva e inferencial: X² y correlación Pearson, usando el paquete estadístico SPSS-21. Resultados: En las maloclusiones II ángulo bajo y alto, y en la clase III ángulo bajo mayormente no presentan discrepancia posterior; en la maloclusión clase III ángulo alto si presenta en su mayoría discrepancia posterior. Las maloclusiones clase II alto y bajo muestran un doble plano oclusal, mientras que las maloclusiones III alto y bajo mayormente presentan un solo plano oclusal. En las maloclusiones clase II con ángulo bajo existe relación directa entre la discrepancia posterior, el plano oclusal. Conclusiones: Con ángulo alto no hay relación en la discrepancia posterior y plano oclusal. En la maloclusión clase III con ángulo alto y bajo no se encontró relación estadísticamente significativa entre discrepancia posterior y plano oclusal. (AU)


Objectives: To relate the occlusal plane to the posterior discrepancy by applying the kim cephalogram and the analysis of the dental framework of Dr Sato. Material and methods: The present study was carried out on cephalometric radiographs of 80 patients between the ages of 15 and 25 years of age, divided into 4 groups whose size was determined by formula: 20 lateral radiographs of patients with malocclusion class II low angle, 20 with high angle, 20 xrays of patients for malocclusion class III low angle and 20 with high angle. The technique of data collection was radiographic observation, which was performed through its respective instrument. Data analysis was performed using descriptive and inferential statistics: X² and Pearson correlation, using the statistical package SPSS-21. Results: In the low and high angle II malocclusions, and in the low angle III class, there is no posterior discrepancy; In the class III malocclusion high angle if it presents in its majority later discrepancy. High and low class II malocclusions show a double occlusal plane, while the high and low III malocclusions mostly present a single occlusal plane. In class II malocclusions with low angle there is a direct relationship between the posterior discrepancy, the occlusal plane. With high angle there is no relation in the posterior discrepancy and occlusal plane. Conclusions: In the class III malocclusion with high and low angle there was no statistically significant relationship between posterior discrepancy and occlusal plane. (AU)

ABSTRACT

O objetivo básico do tratamento de Ortodontia é restaurar a harmonia do esqueleto maxilo-facial através do controle da dimensão vertical e do plano oclusal. O método multi-bráquetes, amplamente usado na terapia ortodôntica, permite o controle tridimensional dos dentes. Durante muito tempo os ortodontistas não aproveitaram esse controle, concentrando-se apenas no movimento mesio-distal, uma vez que a principal técnica para alinhar e melhorar o perfil do paciente era movendo os caninos distalmente, permitindo em seguida a retração dos incisivos. Em 1967, Dr. Young Kim, em Boston, reconheceu a importância da verticalização do eixo dos dentes, do controle vertical e introduziu os "Multiloop Edgewise Arch Wire" (MEAW). Nos anos 80, Dr. Sadao Sato, no Japão, propôs novas ideias para esses arcos, usando-os para diferentes tipos de más oclusões, controlando a dimensão vertical e alterando a inclinação do plano oclusal com notável êxito. Apesar da eficiência biomecânica dos Arcos MEAW, eles demandam muito trabalho, pois são várias dobras complicadas e, para tanto, requerem uma formação específica da técnica. Outro inconveniente desses arcos é o seu volume na boca do paciente, o que dificulta a higiene e também é antiestético. Todos esses fatores têm dificultado a expansão da técnica MEAW, no entanto, foi encontrada uma maneira de mudar a reduzida constante elástica dos arcos MEAW, os quais são feitos com fio Elgilloy 0.16" x 0.22", utilizando um fio estruturado mais simples. Recentemente, foi introduzida no mercado uma nova liga chamada GUMMETAL. As características do GUMMETAL estão perfeitamente adequadas para superar todos os inconvenientes dos arcos MEAW, mencionados anteriormente.(AU)


The basic goal of orthodontic treatment is to restore the harmony of the maxillofacial skeleton by controlling the vertical dimension and the occlusal plane. The multi-bracket method, widely used in orthodontic therapy, allows three-dimensional control of teeth. For a long time, orthodontists did not take advantage of this control, concentrating only on the mesio-distal movement, since the main technique to align and improve the patient's profile was to move the canines distally, allowing the incisors to retract. In 1967, Dr. Young Kim, in Boston, recognized the importance of vertical axis of the teeth, the vertical control and introduced the Multiloop Edgewise Arch Wire (MEAW). In 1980, Dr. Sadao Sato, in Japan, proposed new ideas for these arches, using them for different types of malocclusions, controlling the vertical dimension and changing the inclination of occlusal plane with remarkable success. Despite the biomechanical efficiency of the MEAW arches, they require a lot of work, as they are several complicated folds and, for that, requires a specific technique training. Another drawback of these arches is the volume in the patient's mouth, which makes hygiene difficult and is also anti-aesthetic. All these factors have made it difficult to expand the MEAW technique, however, a way has been found to change the reduced elastic constant of the MEAW arches, which are made with Elgilloy .016x.022" wire, using a simpler structured wire. Recently, a new alloy called GUMMETAL was introduced in the market. The characteristics of GUMMETAL are perfectly suited to overcome all the drawbacks of the MEAW arches mentioned above.(AU)

ABSTRACT

Multiloop Edgewise Archwire Technique es una técnica desarrollada en los años 60 por Young H. Kim, la cual ha tenido un fuerte desarrollo en los países de Asia, especialmente Japón y Corea, por el Prof. Sadao Sato de la Universidad de Kanagawa, Japón. En la experiencia de la filosofía MEAW se ha dado particular importancia al tratamiento no quirúrgico de clases III y mordidas abiertas esqueletales. La discrepancia posterior (CP), concepto nuevo para la ortodoncia occidental, es considerada para determinar la remoción temprana de los terceros molares debido a su importancia como factor coadyuvante en la recidiva de los tratamientos de ortodoncia, especialmente el apiñamiento incisivo y en particular en la orientación del Dr. Sato, debido a su importancia en el desarrollo de la DP, que como se ha mencionado, es un factor etiopatogénico en el desarrollo de las maloclusiones esqueletales y mordidas abiertas antes, durante y postratamiento de ortodoncia.

ABSTRACT

El tema de la extracción preventiva de los terceros molares, ha estado sometido durante mucho tiempo a un extenso debate. Son muchos los artículos basados en la evidencia, que apuntan a no considerar este procedimiento como una maniobra justificada, si no hay sintomatología que lo amerite. Los resultados de las investigaciones, concluyen especialmente que no hay evidencia que sustente que los terceros molares sean causantes de apiñamiento dentario tardío. Dichas investigaciones no han considerado sin embargo las investigaciones del Profesor Sadao Sato referidas al concepto de discrepancia posterior y los terceros molares, y su rol como factor etiopatogénico en el apiñamiento tardío, desarrollo de mordida abierta y recidiva post tratamiento de ortodoncia. En el presente artículo se desarrolla parte del debate y se presenta la filosofía MEAW – Multiloop Edgewise Arch Wire- como un efectivo método de tratamiento de las secuelas de Discrepancia Posterior.


The subject of the preventive extraction of third molars, has been under an extensive debate during long time. The articles based on the evidence are many, that aim not to consider this procedure like a justified maneuver, if there is no symptoms that justify it. The results of the investigations conclude specially that there is no evidence that it sustains those third molars is causes of delayed dental crowding. These investigations have not considered nevertheless the investigations of Professor Sadao Sato referred to the concept of posterior discrepancy and third molars, and it roll like etiopatologic factor in the delayed crowding, development of open bite and post orthodontic relapse. In the present article part of the debate is presented and it developed the MEAW philosophy - Multiloop Edgewise Arch Wire- like an effective method of treatment of the sequels of Posterior Discrepancy.
