Más en particular, el objeto de la invención se centra en un dispositivo de ortodoncia del tipo que tiene como finalidad producir la expansión entre las piezas dentarias de la parte derecha e izquierda del paladar, el cual presenta una innovadora configuración que, ventajosamente, permite realizar dicha operación permitiendo regular de manera independiente el grado de expansión a implementar en la parte anterior y en la parte posterior del paladar, de forma que proporciona mayor efectividad ajustándose a las diferentes necesidades de cada caso y, además, su diseños sencillo y diáfano, facilita la limpieza e higiene. More particularly, the object of the invention is focused on an orthodontic device of the type that aims to produce the expansion between the teeth on the right and left side of the palate, which has an innovative configuration that, advantageously, allows to perform This operation allows to independently regulate the degree of expansion to be implemented in the anterior and posterior part of the palate, so that it provides greater effectiveness adjusting to the different needs of each case and, in addition, its simple and diaphanous designs, facilitates Cleaning and hygiene.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector técnico de la ortodoncia, centrándose particularmente en los aparatos y dispositivos destinados a producir la expansión del paladar . The scope of the present invention is framed within the technical sector of orthodontics, focusing particularly on the devices and devices intended to produce the expansion of the palate .
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Los dispositivos expansores de paladar usados actualmente en ortodoncia llevan mecanismos expansores que producen una expansión paralela la parte derecha e izquierda del paladar, bien entre una pieza dentaria de la parte derecha del paladar respecto a otra de la parte izquierda, o bien entre conjuntos de piezas dentales de la zona derecha y la zona izquierda. The palate expander devices currently used in orthodontics have expander mechanisms that produce a parallel expansion of the right and left part of the palate, either between a tooth on the right side of the palate with respect to another on the left side, or between sets of pieces of the right zone and the left zone.
En muchas ocasiones, sin embargo, el paciente tiene un paladar de suficiente anchura en la parte posterior y estrecho en la parte anterior, o al contrario . On many occasions, however, the patient has a palate of sufficient width at the back and narrow at the front, or vice versa.
En estos casos la expansión en paralelo no es una solución adecuada, pues la expansión de la zona estrecha conlleva la misma expansión de la zona que tiene anchura adecuada, y por tanto lo que solucionamos por un lado lo estropeamos por el otro. Asi pues, el dispositivo expansor de paladar objeto de la invención que se reivindica, tiene como finalidad solucionar de forma sencilla y versátil estos problemas, debiendo señalarse que, al menos por parte del solicitante, se desconoce la existencia de ningún otro dispositivo o invención de aplicación similar que presente unas características técnicas, estructurales y constitutivas semejantes a las que presente el que aquí se preconiza y cuyos detalles caracterizadores en encuentran convenientemente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva del mismo. EXPLICACIÓN DE LA INVENCIÓN In these cases, parallel expansion is not an adequate solution, since the expansion of the narrow zone entails the same expansion of the area that has adequate width, and therefore what we solve on the one hand we spoil on the other. Thus, the palate expander device object of the invention claimed is intended to solve these problems in a simple and versatile manner, it should be noted that, at least by the applicant, the existence of any other device or invention of similar application that presents technical, structural and constitutive characteristics similar to those presented herein and whose characterizing details are conveniently included in the final claims that accompany the present specification thereof. EXPLANATION OF THE INVENTION
De forma concreta, lo que la invención propone, como ya se ha apuntado anteriormente, es un dispositivo para producir la expansión entre piezas o grupos de piezas dentarias de la parte derecha e izquierda del paladar, y que presenta la particularidad de contar con una configuración estructural diseñada para poder realizar dicha operación regulando de manera independiente la expansión de la parte anterior y la posterior del paladar. Specifically, what the invention proposes, as already noted above, is a device to produce the expansion between pieces or groups of teeth on the right and left side of the palate, and which has the particularity of having a configuration structural design designed to perform said operation by independently regulating the expansion of the anterior and posterior part of the palate.
Para ello el dispositivo está formado por diversas piezas que se acoplan entre si, comprendiendo una placa guia central, dos tornillos de regulación, y cuatro deslizaderas, dos con rosca a derechas y dos con rosca a izquierdas. For this, the device is formed by various parts that are coupled together, comprising a central guide plate, two adjustment screws, and four sliders, two with right-hand thread and two with left-hand thread.
La placa guia central provista de guias, una a cada lado, por donde encajan y se desplazan las deslizaderas y que podrá tener longitudes y anchuras diferentes, en función de las dimensiones del paladar, de lo que se quiera ensanchar y de las necesidades del profesional ortodontista . The central guide plate provided with guides, one on each side, where the slides fit and move and that may have different lengths and widths, depending on the dimensions of the palate, what you want to widen and the needs of the professional orthodontist
Los tornillos de regulación están provistos de dos extremos roscados, uno a derechas y otro a izquierdas, donde se insertan en las respectivas roscas de las deslizaderas, tal como se explicará más adelante. La parte central de estos tornillos es ligeramente más gruesa y cilindrica, contando con unos taladros que sirven para insertar una herramienta y realizar el giro del tornillo. Dicha parte cilindrica encaja en una pequeña entalla prevista en cada guia de la placa central, para evitar que los tornillos se desplacen longitudinalmente respecto a la misma. Los tornillos tendrán una longitud total similar a la de la placa guia. The adjustment screws are provided with two threaded ends, one on the right and one on the left, where they are inserted into the respective threads of the sliders, as will be explained later. The central part of these screws is slightly thicker and cylindrical, with holes that serve to insert a tool and make the screw turn. Said cylindrical part fits into a small notch provided in each guide of the central plate, to prevent the screws from moving longitudinally with respect to it. The Screws will have a total length similar to that of the guide plate.
Por último, las deslizaderas son unas piezas que tienen un rebaje que encaja con las guias de la placa guia central, sobre la que se desplazan, y están provistas de un taladro roscado que en dos de ellas es a derechas y en las otras dos a izquierdas, en los que se inserta el tornillo de regulación. Finally, the sliders are parts that have a recess that fits with the guides of the central guide plate, on which they move, and are provided with a threaded hole that in two of them is right and in the other two a left, in which the adjustment screw is inserted.
Estas deslizaderas están provistas asimismo de un orificio en el que se inserta el extremo de alambre que actúa sobre el anclaje de la pieza dentaria a mover. Dicho alambre puede también soldarse sobre la parte superior de la deslizadera, lo que proporcionaría un conjunto de menor en dimensión, unos 4 mm menos, aproximadamente . These slides are also provided with a hole in which the end of the wire acting on the anchor of the tooth to be moved is inserted. Said wire can also be welded on the upper part of the slide, which would provide a set of smaller in size, about 4 mm less, approximately.
Con las descritas piezas, el funcionamiento del dispositivo expansor es el siguiente: With the described parts, the operation of the expander device is as follows:
En cada una de las guías de la placa guía central se montan dos deslizaderas, una con rosca a derechas y otra con rosca a izquierdas, convenientemente insertadas en el lado correspondiente de uno de los tornillos de regulación, los cuales, a su vez, se fijan por su parte cilindrica central en la entalladura de la guía correspondiente, montándose el conjunto en el paladar de forma de una de las guías con su tornillo y sus dos deslizaderas queda en la parte anterior del mismo y la otra en la posterior. In each of the guides of the central guide plate two slides are mounted, one with a right-hand thread and the other with a left-hand thread, conveniently inserted on the corresponding side of one of the adjustment screws, which, in turn, are fixed by its central cylindrical part in the notch of the corresponding guide, the assembly being mounted on the palate in the form of one of the guides with its screw and its two sliders is on the front of the guide and the other on the back.
Haciendo girar uno de los tornillos en un sentido, las deslizaderas insertadas en él se separan, y girando dicho tornillo en sentido contrario, se juntan las deslizaderas. El ajuste del tornillo dispuesto en la guia de la parte anterior es independiente del tornillo de la guia posterior, por lo que puede ajustarse la separación de las piezas dentarias de forma independiente, a voluntad del ortodont ista . By rotating one of the screws in one direction, the sliders inserted in it are separated, and by turning said screw in the opposite direction, the sliders are joined. The adjustment of the screw provided in the guide of the anterior part is independent of the screw of the posterior guide, so that the separation of the teeth can be adjusted independently, at the will of the orthodontist.
Por este motivo, conviene mencionar que, si el ortodontista considera necesario proveer al conjunto con un alambre de unión entre los anclajes de piezas dentarias de un mismo lado, este deberá tener una disposición con elasticidad. For this reason, it should be mentioned that, if the orthodontist considers it necessary to provide the assembly with a connecting wire between the anchors of dental pieces on the same side, it must have an elastic disposition.
En una realización preferida del dispositivo expansor está totalmente realizado en acero inoxidable y tiene una dimensión de unos 15 mm en sentido longitudinal del paladar, mientras que en sentido transversal al paladar, tiene unos 18 mm. Sin embargo, dichas dimensiones son orientativas y se corresponden con otros mecanismos que se usan para expansión paralela con un solo tornillo de regulación, pero obviamente se puede aumentar o reducir su tamaño si ello fuese necesario. In a preferred embodiment of the expander device it is entirely made of stainless steel and has a dimension of about 15 mm in the longitudinal direction of the palate, while in a transverse direction to the palate, it is about 18 mm. However, these dimensions are indicative and correspond to other mechanisms that are used for parallel expansion with a single adjustment screw, but obviously their size can be increased or reduced if necessary.
Visto lo que antecede, se constata que el dispositivo expansor de paladar con regulación anterior y posterior representa una innovación de características desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita. In view of the foregoing, it is found that the palate expander device with anterior and posterior regulation represents an innovation of unknown characteristics until now for this purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that It is requested.
