ATTACHEMENT EXTRACORONAIRE METALLO-PLASTIQUE
POUR PROTHESES DENTAIRES
L'invention est relative à un attachement du type rotulien pour prothèses dentaires du genre comprenant a) une partie mâle, de forme généralement sphérique ou discoide à bords arrondis, initialement en matériau calcinable, obtenue par coulée métallique simultanée avec la chape recouvrant la dent support appartenant à la partie conjointe de la prothèse; b) une partie femelle, dénommée cage, obtenue par coulée métallique simultanée avec la partie adjointe de la prothèse; c) une gaine, interchangeable, en matière plastique, de forme extérieure généralement cylindrique ou cylindroconique, intercalée entre ladite partie mâle métallique et ladite partie femelle également métallique, destinée à assurer la liaison et l'articulation desdites deux parties entre elles; d) une bague métallique, placée concentriquement à l'intérieur de ladite gaine, dans laquelle viendra se loger ladite partie mâle;
L'état de la technique le plus proche est essentiellement contenu dans les documents suivants appartenant aux mêmes déposants a) le brevet FR-2593058 qui décrit la technique de mise en oeuvre des attachements articulés du type ci-dessus décrit; b) la demande de brevet FR-9002069 qui décrit un attachement intracoronaire mâle-femelle du type précédent avec gaine en matière plastique interchangeable à l'intérieur de laquelle a e' été placée une bague métallique fendue, tronconique, non en appui avec la paroi de la gaine, assurant seule la liaison élastique avec la partie mâle de l'attachement.METALLO-PLASTIC EXTRACORONARY ATTACHMENT
FOR DENTAL PROSTHESES
The invention relates to an attachment of the patellar type for dental prostheses of the type comprising a) a male part, of generally spherical or discoid shape with rounded edges, initially made of burn-out material, obtained by simultaneous metal casting with the yoke covering the support tooth belonging to the joint part of the prosthesis; b) a female part, called a cage, obtained by simultaneous metal casting with the adjoining part of the prosthesis; c) a sheath, interchangeable, made of plastic, of generally cylindrical or cylindroconical outer shape, interposed between said metallic male part and said female metallic part, intended to ensure the connection and articulation of said two parts together; d) a metal ring, placed concentrically inside said sheath, in which said male part will be housed;
The closest prior art is essentially contained in the following documents belonging to the same applicants a) patent FR-2593058 which describes the technique for implementing articulated attachments of the type described above; b) patent application FR-9002069 which describes a male-female intracoronary attachment of the above type with interchangeable plastic sheath inside which has been placed a split, frustoconical metal ring, not in abutment with the wall of the sheath, ensuring only the elastic connection with the male part of the attachment.
A l'usage, ledit attachement s'est avéré perdre ses qualités d'élasticité et de rétention, les divers métaux biocompatibles testés n'ayant pas donné satisfaction sur ces paramètres.In use, said attachment was found to lose its elasticity and retention qualities, the various biocompatible metals tested having not given satisfaction on these parameters.
Une première solution technique est décrite dans la demande de brevet FR9115957 (appartenant aux mêmes déposants) qui consiste à intercaler,entre les deux parties de l'attachement, un élément annulaire, ouvert ou fermé, interchangeable, en métal ou en matière souple, apte à assurer la rétention souhaitée entre les deux parties dudit attachement et à servir de joint d'usure, et éventuellement d'étanchéité, à la liaison en question.A first technical solution is described in patent application FR9115957 (belonging to the same applicants) which consists in interposing, between the two parts of the attachment, an annular element, open or closed, interchangeable, made of metal or flexible material, suitable to ensure the desired retention between the two parts of said attachment and to serve as a wear joint, and possibly a seal, for the connection in question.
L'invention, objet des-présentes, a pour but de mettre en oeuvre une nouvelle solution, non équivalente techniquement à la précédente, qui consiste à intercaler, entre la partie mâle et la gaine plastique, une bague métallique qui comporte une première partie, cylindrique, pourvue d'une fente longitudinale, suivie d'une deuxième partie, également cylindrique, située dans le prolongement de la première, pourvue d'une fente transversale dans laquelle débouche la précédente, ladite fente transversale s'étendant sur la quasi-totalité de la circonférence de la bague, la zone non découpée assurant la liaison desdites deux parties entre elles.La paroi extérieure de la première partie de la bague est en appui total sur la paroi intérieure de la gaine de telle manière que, lorsque la partie mâle est dans sa position fonctionnelle à l'intérieur de la première partie de la bague, cette dernière adopte, sous la pression de ladite partie mâle qui possède un diamètre supérieur au diamètre intérieur de la première partie de ladite bague, une forme tronconique, que permet sa fente longitudinale, qui déforme à son tour la paroi de la gaine qui joue le rôle de silentbloc, l'action combinée de la bague métallique et de la gaine plastique ayant pour effet d'accroltre, de manière durable, la rétention de la partie mâle de l'attachement à l'intérieur de la partie femelle de celui-ci et d'assurer son auto-centrage et l'absorption des efforts masticatoires qui ne sont plus transmis directement à la dent support. The object of the present invention is to implement a new solution, not technically equivalent to the previous one, which consists in interposing, between the male part and the plastic sheath, a metal ring which comprises a first part, cylindrical, provided with a longitudinal slot, followed by a second part, also cylindrical, situated in the extension of the first, provided with a transverse slot into which the preceding one opens, said transverse slot extending over almost all of the circumference of the ring, the uncut area ensuring the connection of said two parts together. The outer wall of the first part of the ring is in full support on the inner wall of the sheath so that, when the male part is in its functional position inside the first part of the ring, the latter adopts, under the pressure of said male part which has a diameter e greater than the internal diameter of the first part of said ring, a frustoconical shape, which allows its longitudinal slot, which in turn deforms the wall of the sheath which acts as a silentbloc, the combined action of the metal ring and the plastic sheath having the effect of increasing, in a lasting manner, the retention of the male part of the attachment inside the female part of the latter and of ensuring its self-centering and the absorption of the forces masticatory which are no longer transmitted directly to the supporting tooth.
Les caractéristiques et les avantages de l'invention vont apparaître plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation préféré de celle-ci donné à titre d'exemple seulement et représenté aux dessins annexés. The characteristics and advantages of the invention will appear more clearly on reading the following detailed description of a preferred embodiment thereof given by way of example only and shown in the accompanying drawings.
Sur ces dessins - la figure 1 est une vue en perspective de la bague selon l'invention; - la figure 2 est une vue en coupe de 1a bague positionnée dans la gaine; - la figure 3 est une vue partielle, en coupe, faisant apparaître l'effet de l'insertion de la partie mâle.In these drawings - Figure 1 is a perspective view of the ring according to the invention; - Figure 2 is a sectional view of the ring positioned in the sheath; - Figure 3 is a partial view, in section, showing the effect of the insertion of the male part.

La deuxième partie de ladite bague se termine par une zone élargie (8) destinée à venir se loger, pour en assurer son maintien, dans une rainure pratiquée dans le fond du logement intérieur de la gaine. The ring shown in Figure 1 has a first part (4), cylindrical, provided with a longitudinal slot (5), followed by a second part (7), also cylindrical, located in the extension of the first, provided with 'A transverse slot (6) into which the previous one opens, said transverse slot extending over almost the entire circumference of the ring, the uncut area (10) ensuring the connection of said two parts together. The second part of said ring ends in an enlarged zone (8) intended to be received, to ensure its maintenance, in a groove formed in the bottom of the interior housing of the sheath.
L'ensemble représenté à la figure 2 comporte la bague précédente en position dans la gaine (3) qui comporte une rainure (9) destinée à contenir la zone élargie (8). La partie femelle (2) de la partie adjointe de la prothèse contient ladite gaine. The assembly shown in Figure 2 includes the previous ring in position in the sheath (3) which has a groove (9) intended to contain the enlarged area (8). The female part (2) of the adjoining part of the prosthesis contains said sheath.
L'ensemble représenté à la figure 3 montre l'effet de l'insertion de la partie mâle (1) de l'attachement sur la bague (4) et la gaine (3). The assembly shown in Figure 3 shows the effect of the insertion of the male part (1) of the attachment on the ring (4) and the sheath (3).
Ainsi réalisé, l'attachement, selon l'invention, solutionne, en combinaison, les problèmes d'usure de la liaison, grâce à la bague métallique, et les problèmes de rétention de la partie mâle, grâce à la gaine en matière plastique associée à ladite bague métallique. Thus produced, the attachment according to the invention solves, in combination, the problems of wear of the connection, thanks to the metal ring, and the problems of retention of the male part, thanks to the sheath of associated plastic material. to said metal ring.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté pour lequel on pourra prévoir d'autres variantes, en particulier dans les formes et les matériaux, sans pour cela sortir du cadre de l'invention. Of course, the invention is not limited to the embodiment described and shown for which other variants can be provided, in particular in the shapes and materials, without thereby departing from the scope of the invention.
