Selon une autre caractéristique additionnelle du dispositif selon l'invention, l'électrode est prévue apte à être mise en contact avec le gel lors de la constitution dudit gel par la mise en relation des compartiments. Selon un premier mode de réalisation du dispositif selon l'invention, il consiste en un réceptacle réalisé dans un matériau non-conducteur électriquement, destiné à recouvrir une dent ou plusieurs dents d'une arcade ou des deux arcades, tandis que l'électrode consiste en des moyens conducteurs aptes à s'étendre à l'intérieur dudit réceptacle pour venir au contact du' gel, et à être connectés aux moyens de transmission du courant.According to another additional feature of the device according to the invention, the electrode is provided capable of being brought into contact with the gel during the constitution of said gel by bringing the compartments into contact. According to a first embodiment of the device according to the invention, it consists of a receptacle made of a material electrically non-conductive, intended to cover a tooth or several teeth of an arcade or two arches, while the electrode consists of conductive means able to extend inside said receptacle to come into contact with the ' gel , and to be connected to the current transmission means.

L'invention concerne divers dispositifs de support de produit actif, à savoir de gel conducteur et renfermant des produits de blanchiment tels que du peroxyde. Ces dispositifs consistent en des réceptacles réalisés dans un matériau non-conducteur électriquement, et qui présentent des formes différentes selon leur utilisation.The invention relates to various active product support devices, namely conductive gel and containing bleaching products such as peroxide. These devices consist of receptacles made of an electrically non-conductive material, and which have different shapes according to their use.
Le réceptacle consiste en une gouttière en forme de U, destinée à couvrir une arcade dentaire en entier en vue du traitement de toutes les dents de cette arcade.The receptacle consists of a U-shaped groove, intended to cover an entire dental arch for the treatment of all the teeth of this arch.
Le réceptacle consiste aussi en une gouttière double, susceptible de couvrir simultanément les deux arcades dentaires.The receptacle also consists of a double gutter, capable of simultaneously covering the two dental arches.
Le réceptacle se présente encore sous la forme d'une enveloppe apte à contenir une seule dent, ou sous la forme d'une enveloppe apte à contenir plusieurs dents.The receptacle is still in the form of an envelope adapted to contain a single tooth, or in the form of an envelope capable of containing several teeth.
Quelle que soit sa forme, chacun de ces réceptacles comporte un embout de connexion permettant de le relier au générateur/contrôleur de courant du dispositif pour le blanchiment, en vue de transmettre ce courant au gel contenu dans les réceptacles.Whatever its shape, each of these containers contains a connection tip for connection to the generator / current controller of the device for bleaching, for the purpose of transmitting this current to the gel contained in the receptacles.
On notera que l'embout de connexion peut également être prévu apte à véhiculer de la lumière, dans le cas de l'utilisation d'une activation photonique, et que dans ce cas le réceptacle est prévu apte à diffuser cette lumière soit au travers d'un réseau optique, soit en étant réalisé dans un matériau transparentNote that the connection tip may also be provided capable of conveying light, in the case of the use of a photonic activation, and that in this case the receptacle is provided able to diffuse this light either through an optical network, either by being made of a transparent material
On notera par ailleurs que les réceptacles sont bien entendu prévus aptes à permettre une adaptation sur, respectivement, une ou plusieurs dents, en tenant compte de la présence des dents adjacentes. •Note also that the receptacles are of course designed to allow adaptation to, respectively, one or more teeth, taking into account the presence of adjacent teeth. •
La transmission du courant est réalisée via une électrode qui peut prendre différentes formes. Ainsi, on peut avoir un réceptacle contenant du gel dans lequel est noyée une électrode se présentant sous la forme d'un fil conducteur.The current is transmitted via an electrode which can take different forms. Thus, one can have a receptacle containing gel in which is embedded an electrode in the form of a conductive wire.
Selon une variante, l'électrode se présente sous la forme d'un dépôt ou d'une nappe conductrice recouvrant partiellement ou totalement le fond du réceptacle.According to a variant, the electrode is in the form of a deposit or a conductive sheet covering partially or totally the bottom of the receptacle.
Les réceptacles peuvent être mis en œuvre de manières très différentes, selon notamment leur destination, c'est-à-dire par exemple, s'ils sont destinés à être utilisés chez le praticien ou en privé.The containers can be implemented in very different ways, depending in particular on their destination, that is to say, for example, if they are intended to be used at the practitioner or in private.
Les réceptacles peuvent • ainsi être conditionnés vides en prévision d'être remplis de gel juste avant l'utilisation, lequel est alors conditionné en tube ou seringue, tandis que l'électrode peut être prévue à demeure dans le réceptacle, ou bien mise en place avant remplissage de gel. • the elements may thus be packaged voids forecast to be filled with the gel just prior to use, which is then packaged in a tube or syringe, while the electrode may be provided permanently in the receptacle, or establishment before gel filling.
Il est également possible de prévoir un réceptacle prêt à l'emploi, et dans ce cas jetable après utilisation, contenant le gel et l'électrode, lesquels sont alors isolés de l'air ambiant par l'intermédiaire d'un film à enlever avant utilisation.It is also possible to provide a receptacle ready for use, and in this case disposable after use, containing the gel and the electrode, which are then isolated from the ambient air by means of a film to be removed before use.
Cette version prête à l'emploi permet avantageusement de pré- closer ie produit actif.This ready-to-use version advantageously makes it possible to pre-close the active product.
Selon une variante, adaptable pour l'un et l'autre des dispositifs précités, et dans le but d'un résultat optimal, le gel peut être préparé juste avant utilisation par le mélange de plusieurs composants maintenus préalablement isolés les uns des autres, ainsi que de l'air ambiant. Ceci présente un intérêt du point de vue efficacité, notamment du fait de la relative instabilité de la molécule de peroxyde, en sorte qu'il est préférable de mélanger le peroxyde et Pactivateur au dernier moment.According to one variant, adaptable for the one and the other of the aforementioned devices, and for the purpose of an optimal result, the gel can be prepared just before use by the mixture of several components kept previously isolated from each other, as well as only ambient air. This is of interest from the point of view of efficiency, in particular because of the relative instability of the peroxide molecule, so that it is preferable to mix the peroxide and the activator at the last moment.
Dans une forme préférentielle de 'réalisation, le dispositif selon l'invention consiste en un réceptacle, mono ou multi-dents, présentant au moins deux compartiments contenant chacun un composant, et agencés en sorte de pouvoir, dans un mouvement, rompre la paroi séparant les deux compartiments en sorte de réaliser le mélange de deux composants.In a preferred embodiment of 'the invention, the device according to the invention consists of a receptacle, mono or multi-tooth, having at least two compartments each containing one component, and arranged so as to be able, in a movement, breaking the wall separating the two compartments so as to achieve the mixing of two components.
On notera que le mouvement permettant la mise en présence des différents composants, peut consister en une succession de mouvements assimilable à un malaxage permettant d'obtenir un mélange homogène.Note that the movement allowing the bringing into contact with the different components, may consist of a succession of movements comparable to a mixing to obtain a homogeneous mixture.
De manière non limitative, un tel réceptacle peut se présenter sous la forme d'une cartouche venant de l'aboutement de deux éléments tubulaires, conçus aptes à permettre le coulissement de l'un dans l'autre, et contenant chacun un produit constitutif du gel à savoir pour l'un du peroxyde et pour l'autre un activateur. On comprendra que le coulissement aboutit, après rupture ou escamotage d'une paroi de séparation, au mélange des deux composants.In a nonlimiting manner, such a receptacle may be in the form of a cartridge coming from the abutment of two tubular elements, designed capable of allowing the sliding of one into the other, and each containing a constituent product of the gel to know for one of the peroxide and for the other an activator. It will be understood that the sliding results, after rupture or retraction of a partition wall, the mixture of the two components.
Selon une variante, le réceptacle incorpore l'électrode, et le mouvement permettant le mélange des composants et la constitution du gel a également pour effet de mettre en place l'électrode dans le gel.Alternatively, the receptacle incorporates the electrode, and the movement allowing the mixing of the components and the constitution of the gel also has the effect of setting up the electrode in the gel.
Selon une autre variante, le réceptacle et l'électrode sont disjoints, et le mouvement d'assujettissement de l'électrode au réceptacle a pour effet le mélange des composants et la constitution du gel. Selon un . autre mode de réalisation du dispositif selon l'invention, ce dernier se présente sous ia forme d'une bande de matériau souple et non-conducteur, destinée à être appliquée par une face sur .une ou plusieurs dents.According to another variant, the receptacle and the electrode are disjoint, and the securing movement of the electrode to the receptacle has the effect of mixing the components and constituting the gel. According to one . Another embodiment of the device according to the invention, the latter is in the form of a strip of flexible material and non-conductive, intended to be applied by one face on one or more teeth.
La bande incorpore une multiplicité de cavités s'ouvrant sur la face et dont le fond est garni d'un élément conducteur de courant lui- même relié au travers, d'un fil aux moyens de transmission du courant, tandis que les cavités sont remplis de gel.The strip incorporates a multiplicity of cavities opening on the face and whose bottom is lined with a current-conducting element itself connected thereto, from a wire to the current transmission means, while the cavities are filled. of gel.
En pratique, après enlèvement d'un film de protection, on applique la bande par sa face sur la ou les dents à traiter, en sorte d'obtenir une répartition du gel à la surface de la ou les dents, puis on active les moyens de transmission du courant pour entamer le processus. On décrit maintenant un autre mode de réalisation du dispositif selon l'invention qui est plus particulièrement destiné au traitement des dents dévitalisées, telle qu'une dent dans laquelle est pratiquée une cavité coronaire en remplacement de la pulpe dentaire. Cette cavité coronaire est remplie d'un matériau conducteur qui peut être du gel, dans lequel est introduite une électrode qui en l'occurrence consiste en une simple sonde conductrice noyée dans le matériau conducteur, et liée aux moyens de transmission du courant, par l'intermédiaire d'un fil isolé.In practice, after removal of a protective film, the strip is applied by its face to the tooth or teeth to be treated, so as to obtain a distribution of the gel on the surface of the tooth or teeth, and the means are activated. of current transmission to start the process. Another embodiment of the device according to the invention is described which is more particularly intended for the treatment of devitalized teeth, such as a tooth in which a coronal cavity is used in place of the dental pulp. This coronal cavity is filled with a conductive material which may be gel, into which is introduced an electrode which in this case consists of a simple conductive probe embedded in the conductive material, and connected to the current transmission means, by the intermediate of an insulated wire.
Il y a lieu de noter qu'il peut être nécessaire d'isoler la partie canalaire de la dent afin d'éviter la fermeture du circuit par le biais de celle-ci. Il est donc prévu d'intercaler entre le gel conducteur et la partie canalaire un élément isolant se présentant sous la forme d'une pâte ou analogue en matériau non conducteur, déposé dans le fond de la cavité coronaire. De manière avantageuse, le matériau conducteur est recouvert d'une couche d'un matériau non-conducteur qui permet d'isoler complètement le matériau conducteur et l'électrode du reste de la bouche.It should be noted that it may be necessary to isolate the canal part of the tooth in order to avoid closing the circuit through it. It is therefore planned to insert between the conductive gel and the canal part an insulating element in the form of a paste or the like of non-conductive material deposited in the bottom of the coronal cavity. Advantageously, the conductive material is covered with a layer of a non-conductive material which allows to completely isolate the conductive material and the electrode from the rest of the mouth.
Le matériau consiste en un ciment isolant appliqué par-dessus le gel, et qui de préférence est prévu apte à permettre l'évacuation des gaz susceptibles d'être produits lors du traitement, ce qui peut être obtenu par une certaine porosité de ce ciment.The material consists of an insulating cement applied over the gel, and which preferably is provided capable of allowing the evacuation of the gases that may be produced during the treatment, which can be obtained by a certain porosity of this cement.
Selon un mode de réalisation plus abouti, l'électrode est enfouie dans le matériau conducteur, lequel est recouvert du matériau non- conducteur, tandis qu'un capuchon recouvre la dent pour constituer une électrode externe.According to a more successful embodiment, the electrode is buried in the conductive material, which is covered with the non-conductive material, while a cap covers the tooth to form an external electrode.
Le capuchon est réalisé en matériau non-conducteur, il comporte intérieurement un élément- conducteur relié à un fil en liaison avec les moyens de transmission du courant. Le capuchon est destiné à contenir un matériau conducteur tel que du gel, ce qui permet de fermer le circuit au niveau de la dent, et de réaliser le traitement depuis, simultanément, l'intérieur et l'extérieur de la dent.The cap is made of non-conductive material, it internally comprises a conductive element connected to a wire in connection with the current transmission means. The cap is intended to contain a conductive material such as gel, which closes the circuit at the level of the tooth, and to perform the treatment since, simultaneously, the inside and outside of the tooth.
On notera que pour les autres modes de réalisation du dispositif selon l'invention, l'électrode destinée à fermer le circuit se présente sous la forme un élément conducteur dont la forme est prévue apte à s'adapter à la partie du corps sur laquelle il doit être assujetti. Cette électrode peut ainsi prendre différents aspects, elle peut consister, non limitativement, en un fourreau à enfiler sur le doigt, en un élément imbibé disposé dans la bouche, en un cavalier enfourché sur une lèvre, en une pince apte à être disposée sur un membre à-même la peau, sur le bras par exemple.Note that for the other embodiments of the device according to the invention, the electrode intended to close the circuit is in the form of a conductive element whose shape is provided adapted to adapt to the part of the body on which it must be subject. This electrode can thus take different aspects, it can consist, without limitation, in a sheath to slip on the finger, a soaked element disposed in the mouth, a jumper mounted on a lip, a clamp adapted to be disposed on a member of the same skin, the arm for example.
Par ailleurs, quel que soit le mode de réalisation précédemment décrit, le dispositif selon l'invention est de préférence utilisé en association avec des moyens permettant d'isoler électriquement certaines parties de Moreover, whatever the embodiment previously described, the device according to the invention is preferably used in combination with means making it possible to electrically isolate certain parts of
la bouche, telles que les gencives, les couronnes métalliques, voire certaines dents qui ne doivent pas être traitées, ces moyens consistant en des produits isolants applicables par badigeonnage, pulvérisation, moulage etc.the mouth, such as gums, metal crowns, even some teeth that must not be treated, these means consisting of insulating products applicable by painting, spraying, molding, etc.
De tels produits isolants peuvent consister par exemple en des vernis, des cires dentaires ou autres matériaux. Such insulating products may consist for example of varnishes, dental waxes or other materials.
