Abstract

Palette for the preparation of dental ceramic, comprising a large number of cells and characterised by a body made of porous faience or earthenware, integral with the palette and intended to be filled with water diffused by a capillary effect into the cells.

Description

La préparation de prothèses dentaires en céramique utilise des poudres qui, au iodent de leur élaboration nécessite l'addition d'une certaine quantité d'eau. The preparation of ceramic dental prostheses uses powders which, at the time of their development require the addition of a certain amount of water.

Selon une technique connue ces poudres sont préparées dans des palettes en céramiques poreuses dont la face postérieure est disposée au contact d'une éponge rouillée. According to a known technique, these powders are prepared in porous ceramic pallets, the rear face of which is placed in contact with a rusty sponge.

Ce dispositif a pour avantages d' une part, de maintenir le degré d' huaidité désiré nécessaire à la préparation de la poudre d'autre part, d'empêcher le séchage de la préparation et de permettre de conserver la patte obtenue pour la réalisation de plusieurs prothèses. This device has the advantages on the one hand, of maintaining the desired degree of moisture necessary for the preparation of the powder on the other hand, of preventing the drying of the preparation and of making it possible to preserve the tab obtained for the realization of several prostheses.

Par contre1 un tel dispositif a pour inconvénient la nécessité de aintenir la palette ainsi réalisée au contact d'une éponge imbibée d'eau. On the other hand, such a device has the drawback of needing to maintain the pallet thus produced in contact with a sponge soaked in water.

La présente invention se propose de remédier à cet inconvénient et d'améliorer les performances de la palette. The present invention proposes to remedy this drawback and improve the performance of the pallet.

Le principe utilisé consiste à pourvoir la palette d'un réservoir solidaire de celle-ci et destiné à être rempli d'eau et de doter ce réservoir de moyens de remplissage tels que les alvéoles situées sur la palette se situent en dessous du niveau de 1' eau contenu dans le dit réservoir. The principle used consists in providing the pallet with a tank integral with it and intended to be filled with water and in providing this tank with filling means such that the cells located on the pallet are located below the level of 1 water contained in said tank.

Une réalisation possible de la dite invention est figurée dans le dessin annexé en figure 2, la figure 1 représentant la palette selon l'art antérieur. A possible embodiment of the said invention is shown in the drawing appended to Figure 2, Figure 1 showing the pallet according to the prior art.

La palette est constituée d'un corps en faïence poreuse 1.6. The pallet consists of a body of porous earthenware 1.6.

Les parois sont figurées en 1 et les alvéoles utilisées pour l'élaboration de la poudre céramique en 2. The walls are shown in 1 and the cells used for the preparation of the ceramic powder in 2.

Ces alvéoles peuvent être soient des calottes sphériques ou des cavités de formes rectangulaires. These cells can be either spherical caps or cavities of rectangular shapes.

La palette selon l'invention comporte un fond 6 délimitant une cavité
S et deux trous de remplissage 4.The pallet according to the invention comprises a bottom 6 delimiting a cavity
S and two filling holes 4.

Selon une autre caractéristique de l'invention l'ensemble de la palette reçoit extérieurement une couche d'émail 3 destinée à la rendre étanche à l'exception de l'intérieur des alvéoles. According to another characteristic of the invention, the entire pallet receives an exterior layer of enamel 3 intended to make it watertight, with the exception of the interior of the cells.

L'eau disposée dans la cavité 5 peut ainsi mouiller les alvéoles par eapillarité.  The water placed in the cavity 5 can thus wet the cells by eapillarity.

Selon une autre variante de 1' invention, une couche d'émail est disposée au fond de chaque alvéole. According to another variant of the invention, an enamel layer is placed at the bottom of each cell.

Dans ce cas le praticien dispose d'une surface dure et lisse dans le fond de chaque alvéole qui facilite l'élaboration de la pête de céramique tout en conservant le moyen de maintenir cette pâte au degré voulu d'humidité. In this case, the practitioner has a hard and smooth surface at the bottom of each cell which facilitates the preparation of the ceramic paste while retaining the means of maintaining this paste at the desired degree of humidity.

Selon une autre variante de l'invention la palette est réalisée en deux parties afin de permettre la séparation de la palette proprement dite du fond 6 afin d' en permettre le nettoyage.  According to another variant of the invention, the pallet is produced in two parts in order to allow the separation of the pallet proper from the bottom 6 in order to allow cleaning thereof.
