RESUMO

La principal necesidad de extracción de dientes permanentes a la hora de llevar a cabo un tratamiento ortodóncico se basa fundamentalmente en la obtención de espacio para corregir apiñamientos dentarios, protrusiones o problemas sagitales, consiguiendo así una correcta alineación de los dientes que facilitará la posterior obtención de una oclusión óptima, funcional y estable. Esta alternativa de tratamiento ha sido extensamente debatida en la literatura ortodóncica, generando así una gran controversia a lo largo de los años. Una amplia revisión bibliográfica sobre los factores que pueden verse afectados tras el tratamiento extractivo –perfil facial, estabilidad del tratamiento, estética de la sonrisa, cambios esqueléticos y disfunción craneomandibular- muestra que en ninguno de los casos se aportan mayores ventajas o inconvenientes que con aquellos tratamientos llevados a cabo sin extracciones dentarias (AU)


The main reason to practise permanent teeth extraction in order to perform an orthodontic treatment is focused on achieving a wider space to correct crowding, protrusion or sagital problems. This way, a proper teeth alignment is obtained to ease the treatment with a result of an appropriate occlusion that is also a functional and stable output. This choice has been widely discussed in the orthodontic literature, so a big controversy has been served for years. A review of the literature on the factors being modified during an orthodontic treatment involving the extraction of some teeth –facial profile, treatment stability, esthetic smile, skeletal changing and temporomandibular disfunction- show that no advantages or disadvantages are found while performing a treatment without extractions (AU)

RESUMO

Introducción. La expansión maxilar es uno de los procedimientos terapéuticos más usados en ortodoncia, debido a que no solo afecta a la dimensión transversal, sino que el crecimiento deficiente del maxilar superior puede expresarse en los tres planos del espacio. Numerosos autores han analizado los efectos a nivel transversal de la expansión maxilar en el perímetro de arcada, sin obtener resultados concluyentes. Objetivos. Este trabajo de investigación estudiará la relación que existe entre la expansión maxilar y la ganancia de perímetro de arcada, es decir, investigará qué ganancia de espacio real, para alinear los dientes, se obtiene con la expansión, independientemente del aparato utilizado y de la cantidad de expansión que haya que realizar. Material y Método. Se han seleccionado 50 pacientes de ambos sexos con compresión maxilar y que han sido sometidos a tratamiento ortodóncico mediante expansión maxilar. Se obtuvieron modelos de escayola de los pacientes antes y después de ser tratados y se realizaron medidas lineales para valorar los cambios en la arcada dentaria superior. Resultados. Existe una correlación significativa entre ambas medidas y que, en promedio, por cada milímetro de expansión que se gana, se incrementa aproximadamente 0,65 mm de perímetro de arcada (pendiente = 0,644).Además, existiría la ordenada de 1,349 que refleja un hipotético aumento de 1,35 mm. de la ordenada al inicio de la expansión. Conclusiones. Por cada milímetro de expansión añadido, se ganará 2/3 en el perímetro de arcada y además son la expansión a nivel canino y premolar las que más influyen en la ganancia de perímetro de arcada (AU)


Introduction. The maxillary expansion is one of the therapeutic procedures most used in orthodontics, due to the fact that not only it concerns the transverse dimension, but the deficient growth of the upper jaw can express in three planes of the space. Numerous authors have analyzed the effects to transverse level of the maxillary expansion in the perimeter of arcade, without obtaining conclusive results. Aims. This work of investigation will study the relation that exists between the maxillary expansion and the profit of arch perimeter , that is to say, will investigate what profit of real space, to align the teeth, obtains with the expansion, independently of the used device and of the quantity of expansion that be necessary to realize. Material and Method. There have been selected 50 patients of both sexes by maxillary compression and that have been submitted to orthodontic treatment by means of maxillary expansion. There were obtained models of stucco of the patients before and after being treated and linear measures were realized to value the changes for the maxillary dental arches. Results. A significant correlation exists between both measures and that, in average, for every millimeter of expansion that is gained, increases approximately 0,65 mm of perimeter of arcade (slope = 0,644). In addition, it would exist arranged as 1,349 that reflects a hypothetical increase of 1,35 mm. Of arranged to the beginning of the expansion. Conclusions. For every millimeter of expansion added, it will be gained 2/3 in the perimeter of arcade and in addition they are the expansion to canine level and premolar those who more influence the profit of perimeter of arcade (AU)

RESUMO

Analizamos el problema estético, la relación craneofacial y el problema estructural interno en 511 pacientes españoles maloclusivos de clase 1. Apreciamos cierta tendencia retrognática mandibular y dolicofacial, especialmente a nivel del eje facial, pero no apreciable en todos los parámetros. Estéticamente nuestra población expresó un labio superior largo, mayor protrusión del labio inferior y tendencia hacia la sonrisa gingival. Estructuralmente destacan el pequeño tamaño del cuerpo mandibular y el aumento del ángulo de la deflexión craneal...

RESUMO

En este artículo se presentan los valores cefalométricos del análisis de Ricketts para población española maloclusiva de clase I. Se analizaron para ello 511 pacientes (308 mujeres y 203 varones) maloclusivos de clase I (ll.0 :t 3.1 I años). Los resultados obtenidos muestran múltiples diferencias estadísticamente significativas frente a los valores estándar de Ricketts. Clínicamente el hallazgo más destacado fue la observación de una acusada protrusión incisal superior...

RESUMO

Bionator created by BALTERS comes directly from activator but is smaller allowing its use during day and night to achieve mainly: lip closure, tongue in contact with soft palate, make oral area bigger improving its functionality, get a better maxillary relationship making mandible longer and improve tongue position. The principle that a new neuromuscular pattern conducted by appliance drives to development of a new morphologic pattern. Its activity on neuromusculature is neither well documented nor studied. Actually it is admitted that craniomandibular muscles contraction depends on neural pattern of this muscles during movement. This pattern is modified by continuous sensorial feed-back coming from dentition, T.M.J., and muscular and tendinal length and strength receptors. Clinical studies on mandibular advancement, show that occlusion alteration in sagittal mandibular reposition drives to spontaneous activity changes in muscles and to changes in electromyographic rest of certain muscles like the temporal. In some cases it is founded an increase in molar bite due to anterior mandibular reposition force. Clinical studies on mandibular advancement show changes on mandibular muscles spontaneous activity and possibility of modifications of E.M.G. rest level of temporalis. In some cases an increasing of bite force on first molars is founded. Electromyographic changes appear in children early, and produce a new functional position that changes morphology. Feed-back information comes from periodontal and muscular receptors. Patients treated show lip closure without strength, better tongue positioning and swallowing, and lower tension on suprahyoid muscles.
