Description

Dispositivo para la práctica de la ortodoncia.Device for the practice of orthodontics.

Campo de la técnicaTechnical field

La presente invención concierne a un dispositivo para la práctica de la ortodoncia, y más particularmente a un dispositivo del tipo denominado "bracket" que suele aplicarse eventualmente sobre un diente de un usuario/a para servir de soporte a un elemento corrector del mal posicionamiento o inclinación de tal diente.The present invention concerns a device for the practice of orthodontics, and more particularly to a device of the type called "bracket" that is usually applied possibly on a tooth of a user to support to a corrective element of the bad positioning or inclination of such tooth.

Antecedentes de la invenciónBackground of the invention

Existen muchas personas, especialmente pero no exclusivamente niños, que necesitan usar dicho tipo de dispositivos de ortodoncia, comúnmente llamados "bracket" y que sostienen y retienen un alambre constitutivo de un arco que recorre parte de la dentadura y que sirve para corregir una mala inclinación o mal posicionamiento de uno o varios de sus dientes. En el caso de los niños, y debido a su crecimiento continuo, es probable que este alambre o el mismo "bracket" deba retocarse de vez en cuando para adaptarse a cada nueva situación del diente o de la dentadura. Igualmente, es probable que deba recambiarse parte del "bracket" cuando dicha parte se halle desgastada por el uso. Asimismo será conveniente una operación periódica de mantenimiento y limpieza del propio "bracket". Es por ello que tales dispositivos deben prestarse a un fácil manejo para facilitar la intervención de un odontólogo o especialista.There are many people, especially but not exclusively children, who need to use such devices of orthodontics, commonly called "bracket" and that hold and they retain a wire constituting an arc that runs through part of the denture and that serves to correct a bad inclination or bad positioning of one or more of your teeth. In the case of children, and due to their continued growth, it is likely that this wire or the bracket itself must be retouched from time to time to adapt to each new situation of the tooth or denture. Likewise, part of the "bracket" when said part is worn out by use. A periodic maintenance operation will also be convenient and cleaning of the bracket itself. That is why such devices must lend themselves to easy handling to facilitate intervention of a dentist or specialist.

Se conocen numerosos antecedentes aplicados a la finalidad de la presente invención, pudiendo citar el documento WO 2010/000883 que describe un "bracket" de plástico con tapa-clip autoasociada y variable, y un proceso de fabricación, cual "bracket" es del tipo de material plástico u otro material termoplástico que comprende dos partes: una base que se fija a un diente, y una tapa o cubierta con clip de sujeción. La base tiene un surco para sostener un alambre del arco corrector dental, que se retiene usando la cubierta con clip. Dicha base tiene un pivote de autocentraje que conecta con una cavidad de la cubierta. La misma cubierta o tapa está diseñada en diferentes formas y tamaños y se puede cambiar durante el tratamiento de la ortodoncia para reemplazar el desgaste de la propia cubierta o para cambiar la acción del "bracket", de una acción pasiva a otra activa o viceversa.Numerous antecedents applied to the purpose of the present invention, citing WO document 2010/000883 describing a plastic "bracket" with self-associated and variable lid-clip, and a process of manufacturing, which bracket is of the type of plastic material or another thermoplastic material comprising two parts: a base that it is fixed to a tooth, and a cover or cover with clamping clip. The base has a groove to hold a corrective arch wire dental, which is retained using the clip cover. That base has a self-centering pivot that connects with a cavity of the cover. The same cover or cover is designed in different shapes and sizes and can be changed during the treatment of the orthodontics to replace the wear of the cover itself or to change the action of the "bracket", from one passive action to another active or vice versa.

De hecho, la tapa del documento citado WO 2010/000883 es deslizable sobre la base en el sentido longitudinal del alambre corrector, y tiene una abertura en la que debe quedar encajado el citado pivote o pivotes de la base para inmovilizar la posición de cierre de la propia tapa sobre la base. Para intervenir sobre el alambre corrector hay que separar completamente la tapa de la base.In fact, the cover of the cited document WO 2010/000883 is slidable on the base in the longitudinal direction of the correction wire, and has an opening in which it should be fitted said base pivot or pivots to immobilize the closing position of the lid itself on the base. To intervene the cover must be completely separated from the correction wire base.

También el documento US 2003/0049582 trata de un "bracket" con soporte de ortodoncia que incluye una base de soporte de resina para un arco de alambre y una cubierta unida a la misma base mediante una unión tipo bisagra, con dos pares de tiras que van de la base a la cubierta y permiten la apertura y el cierre de la cubierta sobre la base; en la posición de cierre, una prominencia de la cara interior de la cubierta presiona sobre el alambre. Para cambiar el dispositivo hay que quitar todo el conjunto: base de soporte y
cubierta.
Also document US 2003/0049582 deals with a "bracket" with orthodontic support that includes a resin support base for a wire arch and a cover attached to the same base by means of a hinge type joint, with two pairs of strips that they go from the base to the cover and allow the opening and closing of the cover on the base; in the closed position, a prominence of the inner face of the cover presses on the wire. To change the device you have to remove the whole set: support base and
cover.

Otro documento WO 93/41795 ilustra y describe un "bracket" para ortodoncia que básicamente presenta un cuerpo base que ofrece un surco longitudinal para paso de un alambre corrector dental. De dos paredes laterales interiores de dicho surco sobresalen unos salientes que dicho alambre debe salvar al introducirlo mediante presión en dicho surco; luego, el propio alambre queda retenido por tales salientes. En tal realización no se ilustra ni describe ninguna tapa ni cubierta; la retención de dicho alambre se confía únicamente a los citados salientes.Another document WO 93/41795 illustrates and describes a Bracket for orthodontics that basically has a body base that offers a longitudinal groove for passage of a wire Dental Corrector. Of two inner side walls of said groove protruding protrusions that said wire must save the introduce it by pressure into said groove; then his own wire is retained by such protrusions. In such an embodiment I don't know illustrates or describes any cover or cover; holding said wire is entrusted only to the said projections.

Por otro lado, existen varios documentos relativos al mismo tema de ortodoncia que se centran en el material y fabricación del soporte del "bracket" y en las particularidades de la cara inferior del soporte para fijar éste a la superficie de un diente, e incluso el documento US 2006/0170124 cita la inclusión de un aditivo antibacteriano en el soporte del propio "bracket".On the other hand, there are several documents related to the same topic of orthodontics that focus on the material and manufacture of the bracket bracket and in the particularities of the underside of the support to fix it to the surface of a tooth, and even document US 2006/0170124 cites the inclusion of an antibacterial additive in the support of own bracket.

Descripción detallada de un ejemplo de realizaciónDetailed description of an embodiment example

Haciendo referencia en primer lugar a la figura 1, en la misma se aprecia el presente dispositivo compuesto principalmente por una tapa 1 y un cuerpo base 2, ambos de polisulfona, preferentemente transparente. Dicha tapa 1 consiste en una pieza de configuración delgada y contorno aproximadamente cuadrado, siendo de destacar el que dos lados opuestos 5,6 de la misma tapa perpendiculares a la trayectoria que sigue un alambre corrector dental 3, están biselados en sentidos opuestos constituyendo entre ambos una sección en forma de cola de milano. Asimismo, un primer borde longitudinal 8 de la misma tapa 1 lleva un entrante 9 de contorno parcialmente circular, mientras que en el centro, aproximadamente, de dicha tapa 1 hay una ventana pasante 10 de la cual desciende por la cara interior de la misma tapa 1 un apéndice elástico a modo de lengüeta 11; la tapa se completa con una concavidad 13 de su cara superior próxima a un segundo lado longitudinal 14 opuesto al primero.Referring first to the figure 1, the present composite device is appreciated therein mainly by a cover 1 and a base body 2, both of polysulfone, preferably transparent. Said cover 1 consists of a piece of thin configuration and approximately contour square, being that two opposite sides 5.6 of the same cover perpendicular to the path followed by a wire dental corrector 3, are beveled in opposite directions constituting between them a section in the form of dovetail. Also, a first longitudinal edge 8 of the same cover 1 carries a incoming 9 of partially circular contour while in the center, approximately, of said cover 1 there is a through window 10 from which descends on the inside of the same lid 1 a elastic appendix as a tongue 11; the cover is completed with a concavity 13 of its upper face next to a second side longitudinal 14 opposite the first.

Volviendo a la figura 1, el cuerpo base 2, por su parte, presenta una configuración a modo de bloque que tiene una primera cara 33 que sirve, como ya es conocido, de apoyo y fijación sobre un correspondiente diente (no mostrado) mediante la aplicación de un cemento o composición adhesiva convencional. Asimismo el citado cuerpo base presenta una segunda cara 17 donde destaca un surco longitudinal 16 a propósito para que pase por él una porción 3 del citado alambre corrector dental y quede sostenida dicha porción en el mismo surco 16. Sobre la segunda cara 17 del cuerpo base 2, concerniente a tal surco 16, hay un gran rebajo 18 interrumpido por dicho surco que lo divide en dos partes: una parte 18a y una parte 18b. La parte 18a está abierta por ambos lados longitudinales, mientras que la parte 18b está abierta por un lado hacia aquel surco 16, pero su otro lado queda cerrado por una porción longitudinal 22. Los otros dos lados 24,25 del citado rebajo, perpendiculares al surco 16, presentan sendas inclinaciones de sentidos opuestos e idénticas a los biselados citados 5,6 de la tapa 1, constituyendo el citado rebajo 18 una guía para introducción y deslizamiento de aquella tapa 1.Returning to figure 1, the base body 2, for on the other hand, it presents a block-like configuration that has a first face 33 that serves, as is already known, support and fixation on a corresponding tooth (not shown) by application of a cement or conventional adhesive composition. Also, the said base body presents a second face 17 where a longitudinal groove 16 on purpose so that a portion 3 passes through it of said dental correction wire and said portion is held in the same groove 16. On the second face 17 of the base body 2, concerning such a groove 16, there is a large recess 18 interrupted by said groove that divides it into two parts: a part 18a and a part 18b Part 18a is open on both longitudinal sides, while part 18b is open on one side towards that groove 16, but its other side is closed by a longitudinal portion 22. The other two sides 24.25 of said recess, perpendicular to the groove 16, have different inclinations of opposite directions and identical to the bevels mentioned 5.6 of the cover 1, constituting the cited below 18 a guide for introduction and sliding of that cover 1.

De la referida porción longitudinal 22 que cierra el rebajo 18b sobresale una protuberancia preferentemente circular 27 alineada con el citado entrante 9 de la tapa 1, cuando dicha tapa está acolada al cuerpo base 2. E inmediatamente cerca de un lado donde la parte de rebajo 18a queda abierta hacia el exterior, existe un rehundido 29 que por un extremo desemboca en el surco 16, no es tan profundo como éste, y está alineado con la lengüeta 11 de la tapa 1, y por el otro extremo, tal rehundido está cerrado por una porción de pared 30. En dos costados longitudinales del mismo cuerpo base 2 existen sendos entrantes 31,32 á propósito para asir dicho cuerpo.Of said longitudinal portion 22 which close the recess 18b a protrusion protrudes preferably circular 27 aligned with said inlet 9 of cover 1, when said cover is attached to the base body 2. And immediately near one side where the recess portion 18a is open towards the outside, there is a recess 29 that ends at the end groove 16, is not as deep as this one, and is aligned with the tab 11 of the cover 1, and at the other end, such recess is closed by a portion of wall 30. On two longitudinal sides of the same base body 2 there are both incoming 31.32 on purpose to grab that body.

En la práctica (figura 2), tras la adhesión del cuerpo base 2 á una cara de un diente (no ilustrado) y pase del alambre corrector dental 3 por el surco 16 del mismo cuerpo base 2, la tapa 1 deberá introducirse inicialmente por deslizamiento en la parte del rebajo guía 18a del propio cuerpo base 2, en cuyo momento la lengüeta 11 resbala forzadamente sobre la porción de pared 30 que cierra el rehundido del cuerpo base 2, elevándose dicha lengüeta gracias a su elasticidad e introduciéndose momentáneamente en la abertura
10.
In practice (figure 2), after the adhesion of the base body 2 to a face of a tooth (not illustrated) and pass the dental corrector wire 3 through the groove 16 of the same base body 2, the cover 1 should initially be introduced by sliding in the part of the guide recess 18a of the base body 2 itself, at which time the tongue 11 slips forcefully on the wall portion 30 that closes the recess of the base body 2, said tongue rising due to its elasticity and being momentarily inserted into the opening
10.

Una vez que haya salvado dicha porción 30 que cierra el rehundido 29 (figura 3) la lengüeta 11 recobrará su posición descendida, entrando en el rehundido 29 y la tapa 1 podrá seguir deslizándose por el rebajo 18b hasta hacer tope con la porción 22 que cierra dicha parte de rebajo 18b y encajar a presión el entrante elástico 9 de la tapa 1 en la protuberancia 27 del cuerpo base 2 (figura 4).Once you have saved that portion 30 that close the recess 29 (figure 3) the tongue 11 will recover its position lowered into recess 29 and cover 1 may continue sliding down recess 18b until it stops portion 22 closing said recess portion 18b and snapping the elastic recess 9 of the lid 1 in the extrusion 27 of the base body 2 (figure 4).

Para facilitar la elasticidad del citado entrante 9 de la tapa 1, se ha previsto que dicho entrante comunique con un corte longitudinal parcial 30 de la misma tapa. Este corte 30 permitirá la eventual separación de los dos lados del propio entrante 9.To facilitate the elasticity of the aforementioned incoming 9 of the cover 1, it is provided that said incoming communicate with a partial longitudinal cut 30 of the same lid. This cut 30 will allow the eventual separation of the two sides of the own incoming 9.

Para acceder y manipular el citado alambre 3 (figura 5), un odontólogo o especialista sirviéndose de un instrumento puntiagudo (no ilustrado) que encajará en la concavidad 13 de la tapa 1, podrá deslizar ésta hacia atrás, abriéndola hasta el punto en que su lengüeta 11 haga tope con la porción 30 del rehundido 29, con lo que el cuerpo base 2 quedará parcialmente abierto, lo suficiente para dejar al descubierto la porción de alambre 3 que pasa por el surco 16, con lo que el odontólogo podrá intervenir fácilmente en ella.To access and manipulate said wire 3 (figure 5), a dentist or specialist using a pointed instrument (not illustrated) that will fit into the concavity 13 of cover 1, you can slide it back, opening it until the point where its tongue 11 abuts the portion 30 of the recessed 29, so that the base body 2 will be partially open, enough to expose the portion of wire 3 that passes through groove 16, so that the dentist can intervene easily in it.

En definitiva, gracias al entrante 9 de la tapa 1 encajado en la protuberancia 27 del cuerpo base 2, la tapa permanece asegurada y cerrada sobre la segunda cara 17 del cuerpo base 2 y, gracias a la lengüeta 11 la misma tapa puede retroceder, sin caerse, y dejar al descubierto el surco 16 con el alambre corrector dental 3.In short, thanks to incoming 9 of the lid 1 embedded in the protuberance 27 of the base body 2, the cover remains secured and closed on the second face 17 of the body base 2 and, thanks to the tongue 11 the same cover can go back, without falling, and exposing groove 16 with the wire dental corrector 3.

A un experto en la técnica se le ocurrirán modificaciones y variaciones a partir de los ejemplos de realización mostrados y descritos sin salirse del alcance de la presente invención según está definido en las reivindicaciones adjuntas.A person skilled in the art will come up with modifications and variations from the examples of embodiment shown and described without departing from the scope of the present invention as defined in the claims attached.
