Abstract

A sump for locating a temporary cast replacement tooth comprises a squat tubular body of polycarbonate with straight internal walls and convex external walls. Adapts better to adjacent tooth profiles and looks nicer than conventional cylindrical metal sumps, may be tinted to a pseudo ivory colour. The segmental wall section provides adequate stiffness for supporting crowns for molar or premolar teeth. Sump typically has bores of 7-12 mm dia., to suit different tooth sizes and forms.

Description

L'invention concerne une bague pour la realisation de prothèses dentaires provisoires. The invention relates to a ring for making temporary dental prostheses.

Le problème des protheses provisoires en odontologie se pose avec une certaine acuité pour deux raisons au moins. La première est que l'on essaie de conserver au patient un bon coefficient masticatoire en attendant Sa prothèse définitive. La seconde est que cette prothèse provisoire doit hêtre aussi esthetique que possible. The problem of provisional dentures arises with a certain acuity for at least two reasons. The first is that we try to keep the patient a good masticatory coefficient while waiting for his final prosthesis. The second is that this provisional prosthesis should be as aesthetic as possible.

Il est déjà connu de réaliser des prothèses dentaires provisoires au moyen d'une bague que l'on place à l'emplacement de la dent, et que l'on remplit de résine par exemple. Les bagues connues présentent certains inconvénients. Tout d'abord elles sont en métal, ce qui est inesthétique. Ensuite, elles sont strictement cylindriques, ce qui se remarque tres vite. It is already known to produce temporary dental prostheses by means of a ring which is placed at the location of the tooth, and which is filled with resin for example. Known rings have certain drawbacks. First of all they are made of metal, which is unsightly. Then, they are strictly cylindrical, which is noticed very quickly.

L'invention a pour but de proposer des prothèses provisoires parti culièrement esthétiques, evitant les inconvénients précédents et retablissant l'occlusion et les points de contact avec les dents adjacentes. The object of the invention is to propose provisional prostheses which are particularly aesthetic, avoiding the above drawbacks and restoring the occlusion and the points of contact with the adjacent teeth.

L'invention a pour objet une bague pour la réalisation de prothèses dentaires provisoires, caractérisée en ce qu'elle est en polycarbonate à parois extérieures convexes et parois internes droites. The subject of the invention is a ring for producing temporary dental prostheses, characterized in that it is made of polycarbonate with convex outer walls and straight inner walls.

D'autres caracteristiques de l'invention ressortiront de la description qui suit faite avec référence au dessin annexe sur lequel on peut voir une vue extérieure perspective d'un exemple de réalisation d'une bague pour prothèse selon l'invention. Other characteristics of the invention will emerge from the description which follows, given with reference to the accompanying drawing in which an external perspective view of an exemplary embodiment of a prosthesis ring according to the invention can be seen.

Sur le dessin on peut voir que la bague 1 selon l'invention est réalisée en polycarbonate, ce qui lui donne un aspect esthétique apprécié, renforcé par la présence de parois extérieures convexes 2. Les parois internes 3 sont droites car la bague doit recevoir de la resine, afin de constituer une face occlusale. In the drawing it can be seen that the ring 1 according to the invention is made of polycarbonate, which gives it an appreciated aesthetic appearance, reinforced by the presence of convex external walls 2. The internal walls 3 are straight because the ring must receive the resin, in order to constitute an occlusal face.

On peut choisir des dimensions interieures de 7 à 12 mm. par exemple, pour pouvoir adapter les bagues à toutes les tailles et aux différents types de dents. You can choose interior dimensions from 7 to 12 mm. for example, to be able to adapt the rings to all sizes and different types of teeth.

Ces bagues selon l'invention conviennent pour la confection des couronnes dentaires pour prémolaires ou molaires, par exemple. Elles peuvent également servir de coffrage à l'élaboration de couronnes provisoires esthétiques sur des préparations atypiques, telles que des dents à dénudation radiculaires, par exemple, par adjonction de résine à l'intérieur de la bague. These rings according to the invention are suitable for making dental crowns for premolars or molars, for example. They can also serve as formwork for the development of esthetic provisional crowns on atypical preparations, such as teeth with root stripping, for example, by adding resin to the inside of the ring.

Les polycarbonates utilisés pour la confection de la bague selon l'invention lui donnent une teinte très voisine de la dent naturelle, qui convient très bien pour une prothèse provisoire.  The polycarbonates used for making the ring according to the invention give it a shade very close to that of the natural tooth, which is very suitable for a temporary prosthesis.
