Abstract

Thick-walled, insulating box has groups of sources of infra-red ultra-violet and polarised visible light positioned around the interior. The appropriate source can be activated by a programming switch. The enclosure is also equipped with a timer (2). A source of micro waves is positioned underneath the sample stage. Molecular absorption by the substances in the samples causes local heating which may be desirable to the polymerisation process. The door to the chamber is hinged and has three independent elements. One of these is transparent to allow usual inspection of the samples, another is heavily tinted or incorporates a special filter, to allow observation during the exposure, and the third is opaque to prevent all escape of harmful radiation.

Description

La présente invention concerne le domaine de traitement de produits polymérisables à froid sous diverses sources de rayonnement, et a pour objet une enceinte pour la polymérisation à froid de tels produits, en particulier de produits de restauration esthétique et fonctionnelle des dents. The present invention relates to the field of treatment of products which can be polymerized cold under various sources of radiation, and relates to an enclosure for the cold polymerization of such products, in particular products for esthetic and functional restoration of teeth.

Actuellement, les restaurations esthétiques et fonctionnelles des dents sont généralement effectuées au moyen de résine, de porcelaine ou de produits photopolymérisables réagissant sous un rayon lumineux avec ou sans apport de chaleur. Currently, esthetic and functional restorations of teeth are generally carried out using resin, porcelain or photopolymerizable products reacting under a light beam with or without heat input.

Actuellement, le traitement des produits au moyen des rayons lumineux s'effectue par l'intermédiaire de gaines en fibres de verre ou de gaine remplies d'un liquide de transport, la lumière-jaillissant à l'extrémité des gaines. De ce fait, ltopérateur est exposé à un danger d'éblouissement, qui, bien que ne provoquant pas de lésion de l'oeil, cause des troubles passagers pénibles. En outre, le temps de travail avec ces rayons est très réduit afin d'éviter un aveuglement de l'opéra- teur, ou des points lumineux sur la rétine, ou encore le daltonisme. Currently, the treatment of products by means of light rays is carried out by means of glass fiber sheaths or sheaths filled with a transport liquid, the light-gushing at the end of the sheaths. As a result, the operator is exposed to a danger of dazzling, which, although not causing damage to the eye, causes painful transient disturbances. In addition, the working time with these rays is very short in order to avoid blindness of the operator, or bright spots on the retina, or color blindness.

La présente invention a pour but de pallier ces incon vénients.  The present invention aims to overcome these disadvantages.

Elle a, en effet, pour objet une enceinte pour la polymérisation à froid de produits, en particulier de produits de restauration esthétique et fonctionnelle des dents, caractérisée en ce qu'elle est constituée par un caisson muni de parois isolantes et fermé par une porte montée sur charnière et comportant plusieurs éléments indépendants pouvant pivoter sur la charnière, par une ou plusieurs sources de rayonnement infrarouge, par une ou plusieurs sources de rayonnement ultraviolet, par une ou plusieurs sources de lumière polarisée, par un générateur à micro-ondes servant de support aux produits à traiter, par un ou plusieurs sélecteurs de la source d'énergie ou du groupe de sources d'énergie à utiliser, par un branchement électrique, et par un dispositif de règlage du temps d'exposition, cette enceinte permettant notamment une utilisation en laboratoire, sans danger pour l'opérateur. It has, in fact, for an enclosure for the cold polymerization of products, in particular products for esthetic and functional restoration of teeth, characterized in that it is constituted by a box provided with insulating walls and closed by a door mounted on a hinge and comprising several independent elements which can pivot on the hinge, by one or more sources of infrared radiation, by one or more sources of ultraviolet radiation, by one or more sources of polarized light, by a microwave generator serving as support for the products to be treated, by one or more selectors of the energy source or group of energy sources to be used, by an electrical connection, and by a device for adjusting the exposure time, this enclosure allowing in particular a use in laboratory, safe for the operator.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec réfé rence aux dessins schématiques annexés, dans lesquels la figure 1 est une vue en coupe d'une enceinte conforme à l'invention ; la figure 2 est une vue en perspective de l'enceinte, et la figure 3 est une vue en coupe de la porte. The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which FIG. 1 is a sectional view of an enclosure according to the invention; Figure 2 is a perspective view of the enclosure, and Figure 3 is a sectional view of the door.

Conformément à l'invention, et comme le montrent, plus particulièrement, à titre d'exemple, les figures 1 et 2 des dessins annexés, l'enceinte pour la polymérisation à froid de produits, en particulier de produits de restauration esthétique et fonctionnelle de dents, est essentiellement constituée par un caisson 1 muni de parois isolantes 2 et fermé par une porte 3 montée sur une charnière 4, et comportant plusieurs éléments indépendants pouvant pivoter sur la charnière 4, par plusieurs sources de rayonnement infra-rouge 5, par plusieurs sources de rayonnement ultra-violet 6, par plusieurs sources de lumière polarisée 7, par un générateur à micro-ondes 8 servant de support aux produits à traiter 9, par un sélecteur 10 de la source d'énergie, ou du groupe de sources d'énergie à utiliser, par un branchement électrique 11, et par un dispositif 12 de règlage du temps d'exposition. In accordance with the invention, and as shown more particularly by way of example, FIGS. 1 and 2 of the appended drawings, the enclosure for the cold polymerization of products, in particular of esthetic and functional restorative products. teeth, is essentially constituted by a box 1 provided with insulating walls 2 and closed by a door 3 mounted on a hinge 4, and comprising several independent elements which can pivot on the hinge 4, by several sources of infrared radiation 5, by several sources of ultraviolet radiation 6, by several sources of polarized light 7, by a microwave generator 8 serving to support the products to be treated 9, by a selector 10 of the energy source, or of the group of sources d energy to be used, by an electrical connection 11, and by a device 12 for adjusting the exposure time.

Les sources de rayonnement 5 à 7 sont avantageusement réparties uniformément sur l'ensemble des parois verticales et sur la paroi supérieure du caisson 1 et disposées par groupes de sources différentes, de manière à permettre une uniformisation du traitement à l'intérieur du caisson 1. The radiation sources 5 to 7 are advantageously distributed uniformly over all of the vertical walls and over the upper wall of the box 1 and arranged in groups of different sources, so as to allow uniform treatment within the box 1.

Le générateur de micro-ondes 8 forme le support des produits à traiter 9 et permet de provoquer un échauffement moléculaire desdits produits à coeur lorsqu'un tel traitement est nécessaire. The microwave generator 8 forms the support for the products to be treated 9 and makes it possible to cause molecular heating of said products to the core when such treatment is necessary.

La porte 3 montée au moyen de la charnière 4 sur le caisson 1 présente plusieurs éléments indépendants, de préférence trois 13, 14, 15 pouvant pivoter sur la charnière 4 et constitués, par exemple, l'un, 13, par une vitre transparente permettant de vérifier l'état des produits après traitement, l'autre, 14, par une vitre fortement teintée permettant une surveillance des produits en cours de traitement, et la troisième, 15, par une paroi opaque (figure 3), l'un au moins de ces éléments, 13 à 15, de préférence l'élément 13, ou tous ces éléments étant munis d'un filtre contre les rayonnements électromagnétiques. The door 3 mounted by means of the hinge 4 on the box 1 has several independent elements, preferably three 13, 14, 15 which can pivot on the hinge 4 and constituted, for example, one, 13, by a transparent window allowing to check the condition of the products after treatment, the other, 14, by a strongly tinted window allowing monitoring of the products being treated, and the third, 15, by an opaque wall (Figure 3), one at less of these elements, 13 to 15, preferably element 13, or all of these elements being provided with a filter against electromagnetic radiation.

La porte 3, est, en outre, pourvue d'une serrure de sécurité électrique 16 empêchant toute- ouverture complète de la porte lors du traitement. The door 3 is, moreover, provided with an electric security lock 16 preventing any complete opening of the door during the treatment.

Le sélecteur 10 permet une programmation d'un traitement par sélection d'une source d'énergie ou d'un groupe de sources d'énergie, le temps d'exposition des produits étant réglé au moyen du dispositif 12, qui peut être sous forme d'une minuterie. The selector 10 allows programming of a treatment by selecting an energy source or a group of energy sources, the exposure time of the products being adjusted by means of the device 12, which can be in the form a timer.

Grâce à l'invention, il est possible de réaliser un traitement à froid de produits photopolymérisables, en"travail continu, en particulier en laboratoire, sans danger d'éblouissement pour l'opérateur. En effet, après le façonnage des produits, l'opérateur dispose ceux-ci dans le caisson 1, ferme la porte 3, sélectionne la ou les sources d'énergie, et affiche la durée du traitement, qui s'effectue alors automatiquement sans intervention extérieure. Thanks to the invention, it is possible to carry out a cold treatment of photopolymerizable products, in "continuous work, in particular in the laboratory, without danger of dazzling for the operator. Indeed, after the shaping of the products, the operator places these in the box 1, closes the door 3, selects the energy source (s), and displays the duration of the treatment, which then takes place automatically without external intervention.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. C'est ainsi que l'enceinte peut également être utilisée pour la fabrication de bijoux, ou pour la réalisation de liaisons en électronique.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention. Thus the enclosure can also be used for the manufacture of jewelry, or for the realization of links in electronics.
