Abstract
Les inlays ou onlays composites subissent une faible abrasion occlusale du fait qu'ils sont presque totalement circonscrits par de l'émail naturel. Lorsque le point ou surface de contact 1 subit des dizaines de milliers de mouvement latéraux, il est usé par l'émail de la dent naturelle adjacente, et beaucoup plus vite quand il s'agit de métal ou de céramique. Le dispositif objet de l'invention a pour but de se substituer au point ou à la surface de contact composite en lieu et place de ce demier. Le dispositif point ou surface de contact est caractérisé en ce qu'il a la forme d'un polyèdre à six faces. La face avant 2 polie assure le contact avec la dent adjacente, cette face est rectangulaire avec des angles arrondis 3. La face arrière 4 est plus petite avec des angles arrondis 3. La face avant 2 et la face avant 4 sont reliées par les faces 5,6 et 7,8. La face 5 présente une rainure de rétention 9 qui se prolonge sur les faces 7 et 8.Composite inlays or onlays suffer low occlusal abrasion because they are almost completely enclosed by natural enamel. When the point or contact surface 1 undergoes tens of thousands of lateral movements, it is worn by the enamel of the adjacent natural tooth, and much faster when it comes to metal or ceramic. The object of the invention aims to replace the point or the composite contact surface in place of the latter. The point device or contact surface is characterized in that it has the shape of a six-sided polyhedron. The front face 2 polished ensures contact with the adjacent tooth, this face is rectangular with rounded corners 3. The rear face 4 is smaller with rounded corners 3. The front face 2 and the front face 4 are connected by the faces 5.6 and 7.8. The face 5 has a retention groove 9 which extends on the faces 7 and 8.
Description
Le dispositif objet de l'invention est destiné à la prothèse dentaire. DuThe device which is the subject of the invention is intended for the dental prosthesis. Of
fait de la convexité des faces adjacentes des dents sur l'arcade dentaire, les dents se touchent en un point appelé point de contact D. Ce point de contact plus ou moins serré empêche les aliments de se tasser entre les dents et sont propulsés lors de la mastication de part et d'autre, protégeant ainsi la papille dentaire sous-jacente. Ce point de contact évolue avec l'âge en une surface de contact. Cette surface est plus large que haute. Lorsque le point ou la surface de contact disparaît sur l'une ou les deux dents adjacentes, les aliments se tassent entre les deux dents, provoquant un bourrage alimentaire : ce bourrage détruit progressivement la papille, l'os sous-jacent et favorise l'apparition de caries proximales. Les reconstitutions coronaires, qu'elles soient totales (couronnes) ou partielles (inlays et onlays), doivent satisfaire à cette obligation de point ou de surface de contact. convexity of the adjacent faces of the teeth on the dental arch, the teeth touch at a point called point of contact D. This point of contact more or less tight prevents food from settling between the teeth and is propelled during chewing on both sides, thus protecting the underlying dental papilla. This point of contact evolves with age into a contact surface. This surface is wider than it is tall. When the point or the surface of contact disappears on one or the two adjacent teeth, the food settles between the two teeth, causing a food jam: this stuffing progressively destroys the papilla, the underlying bone and favors the appearance of proximal caries. Coronal reconstructions, whether total (crowns) or partial (inlays and onlays), must satisfy this obligation of point or surface of contact.
L'invention des matériaux composites a permis la réalisation d'inlays et d'onlays qui, du fait de leur esthétisme et de la qualité de leur collage, remplacent de plus en plus les indications des inlays et onlays métalliques. Les dents naturelles étant maintenues par des ligaments se comportent comme des pseudarthroses autorisant lors de la mastication de légers mouvements : ces mouvements assurent l'auto-nettoyage du point ou de la surface de contact. Les inlays ou onlays composites protégés sur leur surface occlusale par l'émail naturel qui les circonscrit subissent de ce fait une faible abrasion. Il n'en est pas de même au niveau du contact avec la dent adjacente. The invention of composite materials has made it possible to produce inlays and onlays which, because of their aesthetics and the quality of their gluing, are increasingly replacing the indications of metallic inlays and onlays. The natural teeth being held by ligaments behave like nonunions allowing slight movements during mastication: these movements ensure the self-cleaning of the point or the contact surface. The composite inlays or onlays protected on their occlusal surface by the natural enamel which circumscribes them thus undergo a low abrasion. This is not the case with the contact with the adjacent tooth.
A la suite de centaines de milliers de petits mouvement latéraux, ces contacts s'usent lorsqu'ils sont opposées à l'émail naturel et beaucoup plus vite encore quand il s'agit de céramique ou de métal. Le dispositif objet de l'invention a pour but d'empêcher l'usure du point ou de la surface de contact de l'inlay ou onlay mais aussi de n'avoir aucune agressivité vis-à-vis du point ou surface de contact de la couronne de la dent adjacente, qu'elle soit naturelle, métallique ou composite. Ce dispositif point ou surface de contact est placé dans l'inlay ou onlay composite à un niveau qui se situe généralement au tiers antérieur et supérieur de la dent. As a result of hundreds of thousands of small lateral movements, these contacts wear out when they are opposed to natural enamel and much more quickly when it comes to ceramic or metal. The object of the invention is to prevent the wear of the point or the contact surface of the inlay or onlay but also to have no aggressiveness vis-à-vis the point or contact surface of the crown of the adjacent tooth, whether natural, metallic or composite. This point device or contact surface is placed in the composite inlay or onlay at a level which is generally at the anterior and upper third of the tooth.
La description qui va suivre ne constitue que quelques modes de réalisation du dispositif objet de l'invention. Dans cette description et les dessins qui correspondent, les mêmes éléments seront repérés par les mêmes nombres. La figure 1 est une vue d'ensemble du dispositif point ou surface de contact 1. The description which follows is only some embodiments of the device object of the invention. In this description and the corresponding drawings, the same elements will be identified by the same numbers. FIG. 1 is an overall view of the point device or contact surface 1.
Ce dessin représente un polyèdre à six faces : une face avant 2 polie assurant le contact avec la dent adjacente 12. Cette face est rectangulaire avec des angles arrondis 3. La face arrière 4, plus petite et rectangulaire, présente également des angles arrondis 3. Les faces avant 2 et 4 sont reliées par les faces 5,6 et 7,8. This drawing represents a polyhedron with six faces: a polished front face 2 ensuring contact with the adjacent tooth 12. This face is rectangular with rounded corners 3. The rear face 4, smaller and rectangular, also has rounded corners 3. The front faces 2 and 4 are connected by the faces 5,6 and 7,8.
La face 5 présente une rainure de rétention 9 située près de la face 4 et qui se prolonge légèrement sur les faces 5 et 7. Le dispositif est réalisé en saphir. La figure 2 est une coupe sagittale médiane passant par l'axe longitudinal de la face 2 suivant AB. On distingue la face avant 2, la face arrière 4, la face latérale 6, la face latérale 5 qui présente une rainure de rétention 9. The face 5 has a retention groove 9 located near the face 4 and which extends slightly on the faces 5 and 7. The device is made of sapphire. FIG. 2 is a median sagittal section passing through the longitudinal axis of the face 2 along AB. We distinguish the front face 2, the rear face 4, the side face 6, the side face 5 which has a retention groove 9.
La figure 3 montre une face 2 augmentée d'un volume lenticulaire 10 nécessaire dans quelques cas pour obtenir un point de contact et non pas une surface de contact. La figure 4 est une vue en coupe verticale de deux dents adjacentes 11 et 12. La dent 11 présente un inlay composite 13 dans lequel est placé le dispositif 1 en contact avec la dent 12 par sa face 2. La coupe passe par l'axe sagittal médian du dispositif 1. La rétention du dispositif 1 est assurée par la rainure de rétention 9. Figure 3 shows a raised face 2 of a lenticular volume 10 necessary in some cases to obtain a contact point and not a contact surface. Figure 4 is a vertical sectional view of two adjacent teeth 11 and 12. The tooth 11 has a composite inlay 13 in which the device 1 is placed in contact with the tooth 12 by its face 2. The cut passes through the axis Sagittal median device 1. The retention of the device 1 is provided by the retention groove 9.
