Abstract
Description
La présente invention concerne un nouvel instrument pour l'obturation des canaux radiculaires au moyen de pâtes, ciments et autres matières obturatrices- diverses, pateuses ou semi-liquides. The present invention relates to a new instrument for closing the root canals by means of pastes, cements and other obturating materials - various, pasty or semi-liquid.
On connaît depuis très longtemps à cet effet des instruments rotatifs constitués en général par un fil métallique enroulé en hélice autour d'un noyau théorique d'allure conique, effilé vers l'extrémité. Rotary instruments for this purpose have been known for a very long time, generally consisting of a metal wire wound helically around a theoretical core of conical shape, tapered towards the end.
Le principe du nouvel instrument selon l'invention consiste à substituer à la progression de pâte par rotation un remplissage et un tapissage complets du canal et des tubulures latérales, grâce à une simple tige lisse conique allongée animée de vibrations rapides, mais subsoniques, multidirectionnelles, d'amplitude progressive vers la pointe de 1 'instru- ment. The principle of the new instrument according to the invention consists in replacing the progression of the dough by rotation with a complete filling and lining of the channel and the lateral tubes, thanks to a simple elongated smooth conical rod animated by rapid, but subsonic, multidirectional vibrations, of progressive amplitude towards the tip of the instrument.
L'invention.vise donc un nouvel instrument destiné à l'obturation des canaux radiculaires, caractérisé en ce qu'il consiste en une tige flexible effilée au moins partiellement conique à une extrémité, et logée à son autre extrémité dans un appareil animé de vibrations subsoniques qui se transmettent à ladite tige sous forme d'oscillations multidirectionnelles d'amplitude croissant progressivement vers la pointe de ladite tige. The invention therefore relates to a new instrument intended for the obturation of the root canals, characterized in that it consists of a flexible tapered rod at least partially conical at one end, and housed at its other end in an apparatus animated with vibrations. subsonic which are transmitted to said rod in the form of multidirectional oscillations of amplitude progressively increasing towards the tip of said rod.
Un tel déplacement oscillatoire de cette tige à l'intérieur du canal a pour effet qu'elle reste constamment en contact avec la surface totale des parois du canal. Si l'on enduit la tige d'un matériau d'obturation pâteux ou fluide, elle va introduire ce matériau dans le canal, quelle que soit la morphologie de celui-ci et les déplacements latéraux de la tige résultant des vibrations subsoniques permettront le remplissage complet non seulement du canal, mais encore des canaux secondaires et tubulures latérales, ainsi que le tapissage uniforme de leurs parois. Such an oscillatory movement of this rod inside the channel has the effect that it remains constantly in contact with the total surface of the walls of the channel. If the rod is coated with a pasty or fluid obturation material, it will introduce this material into the channel, whatever its morphology and the lateral displacements of the rod resulting from the subsonic vibrations will allow filling complete not only of the canal, but also of the secondary canals and lateral tubes, as well as the uniform lining of their walls.
Au surplus, le mouvement de compression latérale pariétale provoque l'oscillation de la portion flexible de l'instrument en engendrant une onde de retour au moment de son retrait ce qui détermine une légère poussée de la pâte vers la pointe, ce qui parfait l'obturation complète des canaux latéraux et du delta-apical. In addition, the lateral parietal compression movement causes the flexible portion of the instrument to oscillate, generating a return wave when it is withdrawn, which causes a slight push of the dough towards the tip, which perfects the complete obturation of the lateral and delta-apical canals.
