ABSTRACT

RESUMEN: Introducción: El patrón de crecimiento facial se establece antes de la aparición del primer molar permanente. Un exceso de crecimiento vertical facial, corresponde a individuos de cara larga, con ángulos goniacos abiertos, alturas faciales inferiores aumentadas y músculos masticatorios de menor área transversal. Esto se asocia a presentar mordida abierta anterior, mordida cruzada, clase II esquelético, entre otros. El entrenamiento muscular masticatorio podría controlar el excesivo crecimiento vertical, generando fuerzas opuestas que favorezcan un crecimiento horizontal. Objetivo: Describir el efecto del entrenamiento muscular masticatorio en el desarrollo del patrón vertical facial en niños. Método: Se realizó una revisión narrativa mediante búsqueda electrónica en las bases de datos PubMed, EBSCO, Scopus, Cochrane, Trip Database y Epistemonikos. Se utilizaron las palabras clave: "músculos masticatorios", "maseteros", "temporales", "masticación", "ejercicio", "entrenamiento", "crecimiento vertical", "patrón vertical", "dolicofacial", "control vertical". Los términos MeSH: "músculos masticatorios", "ejercicio". Resultados: Se seleccionaron 15 artículos de los cuales 9 son ensayos clínicos, 4 son reportes de caso y 2 son estudios observacionales transversales. Conclusiones: El entrenamiento muscular masticatorio tiene efectos positivos, favoreciendo un mayor crecimiento horizontal en niños con patrón vertical. No obstante, faltan estudios y ensayos clínicos para establecer y cuantificar los cambios morfológicos generados por el entrenamiento muscular.


ABSTRACT: Background: The pattern of facial growth is established before the eruption of the first permanent molar. An excess of vertical facial growth corresponds to individuals with long faces, open gonial angles, higher inferior facial heights and smaller masticatory muscles associated with different dental anomalies like anterior open bite, Brodie bite, skeletal class II and others. The masticatory muscle training could control the excessive growth in the vertical dimension, making opposing forces that will favor the horizontal growth in the patient. Objective: Describe the effect of the masticatory muscle training in the development of the vertical pattern in children. Method: A narrative review was done by an electronic research in PubMed, EBSCO, Scopus, Cochrane, Trip Database y Epistemonikos. The following key words were used: "masticatory muscles", "masseter", "temporalis", "mastication", "chewing", "exercise", "training", "vertical growth", "vertical pattern", "dolichofacial", "vertical control". The MeSH terms: "masticatory muscles", "exercise". Results: Fifteen articles were selected, 9 of them were clinical trials, 4 were case reports and 2 were observational studies. Conclusions: The literature review shows that the masticatory muscle training has positive effects, favoring the horizontal growth in children with vertical facial pattern. Nevertheless, there is a lack of studies and clinical trials, that could help us to establish and quantify the morphological changes made by the masticatory muscle training.

ABSTRACT

Cuando se presenta apiñamiento severo, en muchas ocasiones la ubicación que adoptan las estructuras dentarias dificultan el tratamiento, por lo cual se sugiere extracciones asimétricas para permitir de esta manera un tratamiento menos prolongado y con resultados satisfactorios. En este artículo se reporta un caso de biprotrusión dentaria tratado con extracciones de 4 premolares, en una paciente femenina de 20 años y 6 meses, Clase II esquelética, hiperdivergente, con un patrón dolicofacial, Clase III molar bilateral, Clase I canina bilateral, línea media superior coincidente e inferior 4 mm desviada a la izquierda, y no presenta hábitos. En los objetivos de tratamiento se planteó: extracciones asimétricas de primeros premolares superiores e inferiores, corregir el apiñamiento maxilar y mandibular, obtener líneas medias coincidentes, obtener la Clase I molar bilateral, mantener la Clase I canina bilateral. Se logró corregir el apiñamiento severo con una forma de arco adecuada.


In cases of severe crowding, many times the location of dental structures impede treatment, so asymmetrical extractions is suggested to allow a less prolonged treatment with satisfactory results. This article presents a case of dental extractions biprotrution treated with 4 premolars reported, a case of 20 years and 6 months old female patient, skeletal Class II, hyperdivergent, with bilateral dolichofacial pattern, molar Class III bilateral, canine Class I bilateral, upper midline coincident and lower midline 4mm left deviated, is reported and no habits. The goals of treatment are proposed: a symmetric extractions of first premolars upper and lower, correct the maxillary and mandibular crowding, achieve midlines, and obtain bilateral Class I molar and maintain bilateral Class I canine. It was possible to correct severe crowding with a suitable form of arch.

ABSTRACT

Objetivo: avaliar cefalometricamente a influência do Bionatorde Balters no plano oclusal em pacientes dolicofaciais portadoresde maloclusão de Classe II de Angle associadas ao retrognatismomandibular, durante a fase de crescimento. Metodologia:a amostra consistiu de 40 telerradiografias obtidas em doistempos (T1: inicial; T2: após bionatorterapia) de 20 pacientes,sendo 10 do sexo masculino e 10 do sexo feminino com idadesvariando entre 7 e 15 anos (média de 9,03). Resultados e Conclusões:constatou-se um controle bastante eficiente da inclinaçãodo plano oclusal, provocando sua rotação anti-horária, o que éconsiderado essencial na estabilidade dos resultados.


Aim: the purpose of this study is a cephalometric evaluationof the influence of the Balters Bionator on the occlusal plane indolichofacial patients with mandibular Class II malocclusionduring growth period. Methods: the sample comprised of 40 lateralcephalograms taken at two times (T1: initial; T2: after bionatortherapy)from 20 patients, 10 females and 10 males withage ranging between 7 and 15 years (average 9,03). Results andconclusions: an efficient control of the occlusal plane inclinationwas evidenced resulting counter clockwise rotation which wasessential for the achievement and stability of the results.
