Abstract

The dental prosthesis includes an exteriorally threaded socket (1) which is anchored in the patient's jaw. The inside wall of the socket is grooved to retain elastic material (5) which is packed into it. A mounting pin (6) with an exterior thread is screwed into the elastic material. A circular flange (7) around the pin abuts against the upper surface of the elastic material to limit the depth of insertion. A frusto-conical head at the top of the pin mounts the artificial tooth.

Description

La présente invention vise une prothèse implantaire c'est-8-dire une prothèse comprenant une douille filetée destinée à être vissée dans un trou taraudé pratiqué dans le maxillaire et destiné à recevoir un support sur lequel sera fixé la fausse dent. The present invention relates to an implant prosthesis, that is to say a prosthesis comprising a threaded sleeve intended to be screwed into a tapped hole made in the maxilla and intended to receive a support on which the false tooth will be fixed.

I1 existe de très nombreuses prothèses implantaires dont la mise en place est plus ou moins complexe. Oénéralement, on utilise une douille filetée ostéo compatible et celle-ci-est parfaitement fixée au maxillaire. On a constaté qu'après un certain temps, le trou taraudé pratiqué dans le maxillaire tendait à s'évaser au voisinage des bords de sorte que la prothèse ne tenait plus. There are very many implant prostheses whose implementation is more or less complex. Generally, an osteo compatible threaded bushing is used and this one is perfectly fixed to the maxilla. It was found that after a certain time, the tapped hole made in the jaw tended to flare in the vicinity of the edges so that the prosthesis no longer held.

I1 ne faut pas oublier que ces prothèses ont des dimensions très petites, et que lors de la mastication elles doivent supporter des pressions considérables. De plus, la mastication est telle qu'elle engendre des forces qui sont non pas axiales mais également latérales. It should not be forgotten that these prostheses have very small dimensions, and that during chewing they must withstand considerable pressure. In addition, chewing is such that it generates forces which are not axial but also lateral.

Pour cette raison, peu de prothèses implantaires ont une grande longévité.For this reason, few implant prostheses have a long service life.

La présente invention se rapporte à une prothèse implantaire permettant de diminuer les contraintes latérales exercées sur la douille et, par conséquent, d'assurer une meilleure tenue en bouche dans le temps. The present invention relates to an implant prosthesis making it possible to reduce the lateral stresses exerted on the socket and, consequently, to ensure better resistance in the mouth over time.

La prothèse, selon l'invention, est du type comportant une douille faite d'un matériau osteo compatible pourvue d'un filetage extérieur destiné à coopérer avec un taraudage pratiqué dans un maxillaire du patient, ladite douille étant pourvue de moyens pour recevoir un pivot dont l'une des extrémités destinée à faire saillie à l'extrémité de la douille est terminée par un faux moignon destiné à recevoir une dent artificielle, ladite prothèse étant caractérisée en ce qu'un espace libre est ménagé entre la surface latérale externe du pivot et la surface latérale interne de la douille, ledit espace étant rempli d'un matériau souple et élastique. The prosthesis according to the invention is of the type comprising a socket made of a compatible osteo material provided with an external thread intended to cooperate with a tapping performed in a patient's jaw, said socket being provided with means for receiving a pivot. one of the ends of which is intended to project at the end of the socket is terminated by a false stump intended to receive an artificial tooth, said prosthesis being characterized in that a free space is provided between the external lateral surface of the pivot and the internal lateral surface of the sleeve, said space being filled with a flexible and elastic material.

Grâce à cette structure, les efforts exercés sur la fausse dent ne seront pas transmis directement à la douille, mais à travers l'épaisseur du matériau souple et élastique de sorte que ce matériau constituera un amortisseur. Thanks to this structure, the forces exerted on the false tooth will not be transmitted directly to the socket, but through the thickness of the flexible and elastic material so that this material will constitute a shock absorber.

De préférence, la surface interne de la douille comporte des rainures pour faciliter l'ancrage du matériau souple et élastique. Preferably, the internal surface of the sleeve has grooves to facilitate the anchoring of the flexible and elastic material.

La surface latérale externe du pivot peut comporter des rainures pour faciliter son ancrage dans le matériau souple et élastique.  The outer lateral surface of the pivot can have grooves to facilitate its anchoring in the flexible and elastic material.

Suivant une caractéristique constructive particulière le pivot est fileté. According to a particular constructive characteristic, the pivot is threaded.

De préférence, le pivot, au voisinage du faux moignon, comporte un épaulement destiné à coopérer avec le bord de 1 'extrémité correspondante du matériau souple et élastique, pour assurer l'étan- chéité de la prothèse.  Preferably, the pivot, in the vicinity of the abutment, has a shoulder intended to cooperate with the edge of the corresponding end of the flexible and elastic material, to ensure the sealing of the prosthesis.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté à la figure unique qui est une vue en coupe axiale d'une prothèse selon l'invention. The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the single figure which is an axial sectional view of a prosthesis according to the invention.

La prothèse représentée au dessin comprend une douille I en un matériau ostéo compatible et présentant latéralement un filetage 2 destiné à être vissé dans un taraudage 3 pratiqué dans le maxillaire d'un patient. The prosthesis shown in the drawing comprises a socket I made of an osteo-compatible material and having laterally a thread 2 intended to be screwed into a thread 3 made in the maxilla of a patient.

La douille I comporte intérieurement des crans 4 ou des rainures ou un pas de vis pour retenir une épaisseur d'un matériau souple et élastique 5 dans lequel est vissé un pivot 6 qui comporte un épaulement 7 destiné à porter la dent artificielle et en contact avec l'extrémité correspondante du matériau 5 pour assurer un montage étanche. The bushing I internally has notches 4 or grooves or a screw pitch for retaining a thickness of a flexible and elastic material 5 in which is pivoted a pivot 6 which comprises a shoulder 7 intended to carry the artificial tooth and in contact with the corresponding end of the material 5 to ensure leaktight mounting.

L'extrémité libre du pivot 6 est terminé par un faux moignon 8 sur lequel vient se fixer une fausse dent 9, celle-ci étant assujettie par tout moyen, par exemple scellement. The free end of the pivot 6 is terminated by a false stump 8 on which a false tooth 9 is fixed, the latter being secured by any means, for example sealing.

On conçoit que le montage d'une telle fausse dent 9 évite à la douille I d'être directement sollicitée, l'épaisseur 5 constituant un amortisseur. Ainsi, une telle prothèse peut avoir une beaucoup plus grande durée d'utilisation que les prothèses connues. It is understood that the mounting of such a false tooth 9 prevents the socket I from being directly stressed, the thickness 5 constituting a damper. Thus, such a prosthesis can have a much longer duration of use than known prostheses.

Bien entendu, l'invention n'est pas Limitez au mode de réalisation qui vient d'être décrit et qui a été représente; on pourra y apporter de nombreuses modifications de détails sans sortir, pour cela du cadre de l'invention.  Of course, the invention is not limited to the embodiment which has just been described and which has been shown; many modifications of details can be made without departing from the scope of the invention.
