Description

Matière d'obturation des canaux radiculaires des dents Material filling the root canals of teeth
La présente invention concerne une matière d'obturation des canaux radiculaires des dents.The present invention relates to a material for filling the root canals of teeth.
Elle se rapporte plus particulièrement à une matière d'obturation essentielle en endodontie, qui est introduite dans les canaux radiculaires après que l'on ait retiré de façon parfaite les tissus nécrosés, nettoyé et désinfecté ceux-ci.It relates more particularly to an essential filling material in endodontics, which is introduced into the root canals after the necrotic tissue has been removed, cleaned and disinfected.
Un exemple typique de matière d'obturation des canaux radiculaires est généralement désignée «gutta-percha » dans la mesure où la gutta-percha naturelle est le composant principal de la matière d'obturation. Cette gutta-percha naturelle contient du polyisoprène-1 , 4 trans comme composant principal mélangé avec des composants étrangers, telles que d'autres résines naturelles et impuretés variant en fonction de l'endroit de production.A typical example of filling material for root canals is generally designated "gutta-percha" since natural gutta-percha is the main component of filling material. This natural gutta-percha contains polyisoprene-1,4 trans as the main component mixed with foreign components, such as other natural resins and impurities varying depending on the place of production.
Un objectif important lors de l'opération d'obturation est l'étanchéité, et ce particulièrement au niveau apical. Pour parvenir à une bonne qualité d'étanchéité la matière d'obturation à l'état pâteux ou liquide est condensée dans le canal radiculaire.An important objective during the sealing operation is sealing, particularly at the apical level. To achieve good sealing quality, the filling material in a pasty or liquid state is condensed in the root canal.
L'étanchéité et la bonne condensation imposent au praticien de pratiquer des pressions soit latérales soit verticales sur le matériau d'obturation au moyen d'instruments ou de dispositifs de type connu.The tightness and the good condensation require the practitioner to apply pressures either lateral or vertical on the obturation material by means of instruments or devices of known type.
Toutefois, lors de l'exercice de ces pressions, il existe un risque qu'une faible quantité de la matière d'obturation s'échappe au-delà de l'apex entraînant une source d'inflammation et de douleur pour le patient.However, during the exertion of these pressures, there is a risk that a small amount of the filling material will escape beyond the apex causing a source of inflammation and pain for the patient.
Le but de l'invention est donc de proposer une matière d'obturation qui permette de résoudre le risque de dépassement apical dans le canal radiculaire.The object of the invention is therefore to propose a filling material which makes it possible to resolve the risk of apical overshoot in the root canal.
A cet effet, la présente invention a pour objet une matière d'obturation des canaux radiculaires des dents, composée d'un mélange d'une pâte de base d'obturation, du type gutta-percha et de particules non-miscibles dans la pâte de base désignées également « macro-charge », caractérisée en ce que ces particules présentent une taille et une forme déterminées, adaptées en fonction de la dimension de la préparation apicale et en ce que les particules non miscibles dans la pâte sont présentes à une proportion comprise entre 3 et 10% du poids total de la matière d'obturation.To this end, the subject of the present invention is a material for filling the root canals of the teeth, composed of a mixture of a basic filling paste, of the gutta-percha type and of particles immiscible in the paste. basic materials also called "macro-charge", characterized in that these particles have a determined size and shape, adapted according to the size of the apical preparation and in that the particles not miscible in the paste are present in a proportion of between 3 and 10% of the total weight of the filling material.
Selon une caractéristique avantageuse de l'invention, les particules présentent une forme sphérique dont le diamètre est supérieur à la moitié du diamètre de la préparation apicale.According to an advantageous characteristic of the invention, the particles have a spherical shape whose diameter is greater than half the diameter of the apical preparation.
Selon une variante de réalisation, les particules présentent une forme de bâtonnets allongés.According to an alternative embodiment, the particles have the form of elongated rods.
Toujours selon l'invention, les particules sont constituées d'un matériau biocompatible avec la pâte de base, de préférence une hydroxyapatite.Still according to the invention, the particles consist of a material biocompatible with the base paste, preferably a hydroxyapatite.
Selon une caractéristique avantageuse de la présente invention, la pâte de base est constituée de gutta-percha.According to an advantageous characteristic of the present invention, the basic paste consists of gutta-percha.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation non limitatif d'une matière d'obturation de canaux radiculaires des dents.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of a nonlimiting exemplary embodiment of a material for filling the root canals of the teeth.
La matière d'obturation selon l'invention est composée d'un mélange d'une pâte d'obturation du type gutta-percha rendue pâteuse par échauffement lors de l'opération d'obturation et de particules non-miscibles dans la pâte de base désignées également « macro-charge ».The filling material according to the invention is composed of a mixture of a sealing paste of the gutta-percha type made pasty by heating during the sealing operation and of immiscible particles in the base paste also called "macro-load".
Ces particules présentent avantageusement une taille et une forme déterminées adaptées en fonction de la dimension de la préparation apicale. Ainsi, de manière préférentielle, les particules présentent une forme sphérique dont le diamètre est supérieur à la moitié du diamètre de la préparation apicale. Cependant, selon une variante de réalisation, lesdites particules peuvent présenter une forme de bâtonnets allongés.These particles advantageously have a determined size and shape adapted according to the size of the apical preparation. Thus, preferably, the particles have a spherical shape whose diameter is greater than half the diameter of the apical preparation. However, according to an alternative embodiment, said particles may have the form of elongated rods.
On comprend aisément que l'incorporation d'une telle macro-charge présentant des caractéristiques particulières permet de provoquer un effet d'obstruction au niveau de l'apex du canal à obturer de sorte que la pâte d'obturation se retrouve bloquée en amont de l'apex et ne risque pas de dépasser ce dernier, éliminant ainsi les douleurs pouvant être provoquées par des pâtes d'obturation classiques de l'art antérieur tel que décrit ci-dessus.It is easily understood that the incorporation of such a macro-charge having particular characteristics makes it possible to cause an obstruction effect at the level of the apex of the channel to be closed so that the sealing paste is blocked upstream of the apex and is not likely to exceed the latter, thereby eliminating the pain that can be caused by conventional filling pastes of the prior art as described above.
Ainsi de manière pratique, la pâte d'obturation, par exemple de la gutta- percha ou un équivalent mélangé à des particules constituées par exemple d'un matériau biocompatible, de préférence un hydroxyapatite est propulsée dans le canal par un moyen de type connu, par exemple un instrument rotatif de condensation, assurant une condensation verticale et latérale.So in a practical way, the filling dough, for example gutta- percha or an equivalent mixed with particles consisting for example of a biocompatible material, preferably a hydroxyapatite is propelled in the channel by a means of known type, for example a rotary condensing instrument, ensuring vertical and lateral condensation.
Ainsi sous l'effet de la poussée par l'instrument, les particules contenues dans la pâte d'obturation ont tendance à suivre les parois du canal radiculaire qui se remplit de pâte progressivement. Les particules présentant une dimension supérieure à la moitié du diamètre de la préparation apicale dans le cas de particules sphériques permettent de garantir un effet d'obstruction par lesdites particules qui s'agglutinent au niveau apical empêchant ainsi la pâte d'obturation de poursuivre son cheminement au-delà de l'apex.Thus under the effect of the thrust by the instrument, the particles contained in the filling paste tend to follow the walls of the root canal which gradually fills with paste. The particles having a dimension greater than half the diameter of the apical preparation in the case of spherical particles make it possible to guarantee an effect of obstruction by said particles which agglutinate at the apical level thus preventing the filling paste from continuing its path beyond the apex.
Selon un mode de réalisation préférentiel, la matière d'obturation des canaux radiculaires des dents est composée d'une pâte d'obturation du type connu et de particules non miscibles dans la pâte, présentes à une proportion comprise entre 3 et 10% du poids total de la matière d'obturation.According to a preferred embodiment, the material for filling the root canals of the teeth is composed of a filling paste of the known type and particles immiscible in the paste, present in a proportion of between 3 and 10% by weight. total filling material.
On comprend à la lecture de la description ci-dessus que la matière d'obturation selon la présente invention est relativement simple à réaliser et permet de réduire voire de supprimer le risque de dépassement au-delà de l'apex de la matière d'obturation.It will be understood from reading the description above that the filling material according to the present invention is relatively simple to produce and makes it possible to reduce or even eliminate the risk of going beyond the apex of the filling material. .
Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier elle comprend tous les équivalents techniques des moyens décrits. En particulier, l'invention a été décrite en relation avec de la gutta percha. On ne sortirait par du cadre de l'invention en mettant en oeuvre un produit fonctionnellement équivalent. Although the invention has been described in connection with a particular embodiment, it includes all the technical equivalents of the means described. In particular, the invention has been described in relation to gutta percha. It would not go beyond the scope of the invention to use a functionally equivalent product.
