Abstract
Description
La présente invention concerne les implants des tines a etre posés dans le maxillaire et destinés à constituer une sorte de racine artificielle formant un support pour une prothèse dentaire. Par prothèse dentaire on entend aussi bien un dentier partiel qu'un dentier total ou un bridge, etc... The present invention relates to tine implants to be placed in the maxilla and intended to constitute a kind of artificial root forming a support for a dental prosthesis. By dental prosthesis is understood as well a partial denture as a total denture or a bridge, etc ...
Les implants généralement utilisés sont constitués par une ou plusieurs tiges qu'on fixe dans des trous correspondants, préalablement pratiqués dans le maxillaire. The implants generally used consist of one or more rods which are fixed in corresponding holes, previously made in the maxilla.
Souvent, ces tiges sont filetés et on pratique donc dans le maux: re un trou taraudé. La pose d'implants est tres délicate et constitue un veritable acte chirurgical.Often, these rods are threaded and therefore we practice in the wrong: re a tapped hole. The placement of implants is very delicate and constitutes a real surgical act.
De plus, les tiges utilises sont obligatoirement très petites et très souvent on constate que l'implant prend du jeu. On sait, en effet, que les pressions exercées sur les dents sont considérables et qu'elle ne s'exercent pas systématiquement dans les memes directions ; aussi, souvent, le trou dans lequel est fixé l'implant tend à s'évaser, de sorte que l'implant ne tient plus et qu'il devient alors fort délicat de réaliser des prothèses supportables par le patient. In addition, the rods used are necessarily very small and very often we see that the implant takes play. We know, in fact, that the pressures exerted on the teeth are considerable and that they are not systematically exerted in the same directions; Also, often, the hole in which the implant is fixed tends to flare, so that the implant no longer holds and it then becomes very difficult to produce prostheses that can be supported by the patient.
La présente invention concerne un nouvel implant très facile à mettre en place et qui remédie aux divers inconvénients ci-dessus. The present invention relates to a new implant which is very easy to install and which overcomes the various drawbacks above.
L'implant, objet de la présente invention, est constitué d'un manchon dont l'une des extrémité est pourvue d'une denture coupante et comportant des ouvertures latérales. The implant, object of the present invention, consists of a sleeve, one end of which is provided with cutting teeth and comprising lateral openings.
Grâce à cette tlisposition,on peut,en fixant l'implant sur
organe rotatif,directement pratiquer une gorge profonde jans le maxillaire grace à la denture coupante, l'implant
tant, rapidement et sans nécessiter une intervention chirurgical importante, mis en place. Comme l'implant se présente ous forme d" manchon, il peut être beaucoup plus solide et résistant que les implants connus. De plus, grace à ses ouvertures latérales, il s'inclut complétement à l'os qui se reforme er. traversant lesdites ouvertures. Thanks to this arrangement, it is possible, by fixing the implant on
rotary organ, directly practice a deep throat in the maxilla thanks to the cutting teeth, the implant
so much, quickly and without requiring significant surgery, set up. As the implant is presented in the form of a sleeve, it can be much more solid and resistant than known implants. In addition, thanks to its lateral openings, it is completely included in the bone which is reformed and passing through said openings.
De préférence, l'extrémité du manchon opposée à celle comportant la denture coupante est pourvue de moyens pour
permettre la prise d'un organe d'entrainement.Preferably, the end of the sleeve opposite to that comprising the cutting teeth is provided with means for
allow the taking of a training device.
Suivant une caractéristique constructive, les moyens pour permettre la prise d'un organe d'entrainement sont constitués par deux entailles décalées à 180 . According to a constructive characteristic, the means for enabling a drive member to be taken are constituted by two notches offset by 180.
L'invention vise également un outillage pour faciliter a pose de l'implant tel que ci-dessus défini, ledit outillage étant caractérisé en ce qu'il est constitué d'un corp présentant un diamètre extérieur correspondant au diamètre interne du manchon, une extrémité une queue pour permettre sa fixation entre les mors d'un contre angle, des moyens pour le solidariser avec le manchon et, au moins une rainure hélicoïdale latérale s'étendant depuis une extrémité vers l'autre. On réalise ainsi un outillage simple, pratique et qui permet d'évacuer les poussières d'os, le sang, etc... The invention also relates to a tool for facilitating installation of the implant as defined above, said tool being characterized in that it consists of a body having an outside diameter corresponding to the internal diameter of the sleeve, one end a tail to allow its fixing between the jaws of a contra angle, means for securing it to the sleeve and, at least one lateral helical groove extending from one end towards the other. A simple, practical tool is thus produced which allows bone dust, blood, etc. to be removed.
De préference, l'extrémité du corps opposée à celle pourvue dela queue est terminée par une fraise, ainsi, au cours de la pose, on fraise la partie centrale de l'os pour permettre d'allonger la cavité interne du manchon pour assurer une meilleure tenue d'une résine coulée par la suite dans l'extrémité saillante du manchon. Preferably, the end of the body opposite to that provided with the tail is terminated by a milling cutter, so, during installation, the central part of the bone is milled to allow the internal cavity of the sleeve to be lengthened to ensure a better resistance of a resin subsequently poured into the projecting end of the sleeve.
Suivant encore une autre caractéristique eonstructive, le corps est pourvu de deux tétons radiaux destinés à cooprier avec les entailles de l'extrémité correspondante du manchon. According to yet another eonstructive characteristic, the body is provided with two radial pins intended to cohabit with the notches of the corresponding end of the sleeve.
L'invention va maintenant être décriteJavec plus dc détails,en se référant à un mode de réalisation particulier, donné à titre d'exemple seulement et représenté aux dessins annéxés, dans lesquels
Figures 1, 2, 3et 4 montrent schématiquement le procédé de mise en place de l'implant 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 appended drawings, in which
Figures 1, 2, 3 and 4 schematically show the method of placing the implant according to the invention.
Figure 5, est une vue en élevation de l'implant selon l'invention. Figure 5 is an elevational view of the implant according to the invention.
Figure 6, est une vue en coupe suivant la ligne VI VI de la figure 5. Figure 6 is a sectional view along line VI VI of Figure 5.
Figure 7, montre en élevation un outil pour la prise de l'implant selon l'invention. Figure 7 shows in elevation a tool for taking the implant according to the invention.
Figure 8, est une vue en coupe montrant l'implant posé. Figure 8 is a sectional view showing the implant placed.
A la figure 5, on a représenté -un implant, selon l'invention, celui-ci étant constitué d'un manchon 1, dont l'une des extrémités 2 est pourvue de deux entailles 3 tandis que l'autre extrémité est conformée pour présente une denture coupante LI. In Figure 5, there is shown an implant, according to the invention, it being constituted by a sleeve 1, one of the ends 2 of which is provided with two notches 3 while the other end is shaped to has LI cutting teeth.
Le manchon 1 est réalisé en une matière très résistante et au voisinage de la denture 4, il est prévu quatre ouvertures 5, 6, 7 et 8. Les ouvertures 5 et 6 sont alignées et décalées en hauteur, tandis que les ouvertures 7 et 8 sont également alignées et décalées en hauteur. Les ouvertures 5 et 6 par rapport aux ouvertures 7 et 8 sont décalées angulairement de 1800 et pratiquees légé-rement plus près de la denture 4. The sleeve 1 is made of a very resistant material and in the vicinity of the toothing 4, four openings 5, 6, 7 and 8 are provided. The openings 5 and 6 are aligned and offset in height, while the openings 7 and 8 are also aligned and offset in height. The openings 5 and 6 relative to the openings 7 and 8 are angularly offset by 1800 and practiced slightly closer to the toothing 4.
A la figure 7, on a représenté un outil 10 destiné à permettre la prise de l'implant pour sa mise en place. In Figure 7, there is shown a tool 10 intended to allow the implant to be taken for its establishment.
Cet outil est constitué d'un corps 11 comportant à une extrèmité une queue 12 destinée à être -serrée entre les mors d'un contre-angle 16. Le corps 11 comporte deux tétons latu- raux 13 décalés de 1800 et deux rainures hélicoidale 14 tandis que son extrémité libre est terminée par une partie conique 15 constituant une fraise.This tool consists of a body 11 comprising at one end a shank 12 intended to be clamped between the jaws of a contra-angle 16. The body 11 comprises two lateral pins 13 offset by 1800 and two helical grooves 14 while its free end is terminated by a conical part 15 constituting a cutter.
Le diamètre externe du corps Il est sensiblement égal au diamètre interne du manchon 1 de manière qu'il puisse
être engagé dans ledit manchon sans jeu, les tétons 15 s' engageant dans les entailles 3.The external diameter of the body It is substantially equal to the internal diameter of the sleeve 1 so that it can
be engaged in said sleeve without play, the pins 15 engaging in the notches 3.
La référence 17 désigne un maxillaire et la réffrence
18 la gencive.Reference 17 designates a maxilla and the reference
18 the gum.
Les figures 1, 2, 3 et 4 imagent le procédé, selon l'invention, tandis que la figure 8 montre à plus grande échelle et en coupe, l'implant mis en place. Figures 1, 2, 3 and 4 illustrate the process according to the invention, while Figure 8 shows on a larger scale and in section, the implant in place.
Un des avantages très important de l'invention est qu'un tel implant est d'une pose aisée, simple et rapide. One of the very important advantages of the invention is that such an implant is easy to install, simple and quick.
'Pour la pose de l'implant, selon l'invention, on-fixe la queue 12 sur le contre-angle 16 puis on engage l'implant par son extrémité 2 sur le corps 11 de manière que les tétons 13 s'engagent dans les entailles 3. On place ensuite l'implant dans la bouche en regard de l'endroit qui a été préalablement choisi et on commande la rotation de l'outil 10 qui entraine l'implant qui par sa denture 4 découpe la gencive 18 et pratique dans le maxillaire un canal circulaire au centre duquel stérigeounè partie d'os centrale 20.'' For the implant placement, according to the invention, the tail 12 is fixed on the contra-angle 16 then the implant is engaged by its end 2 on the body 11 so that the pins 13 engage in the notches 3. The implant is then placed in the mouth opposite the place which has been previously chosen and the rotation of the tool 10 is controlled, which drives the implant which by its teeth 4 cuts the gum 18 and is practical in the maxilla a circular canal in the center of which sterigeounè part of central bone 20.
L'implant est ainsi enfoncé dans l'os jusqu'à une profondeur détérminée. Au cours dé la mise en place de 1' implant, la partie 15 en forme de fraise découpe dans 1' extrémité libre de la partie d'os centrale 20 une petite cavité conique 21 . Les rainures 14 permettent, lors de la pose de l'implant d'évacuer la poussière d'os, le sang, etc-.. The implant is thus inserted into the bone to a determined depth. During the placement of the implant, the strawberry-shaped part 15 cuts in the free end of the central bone part 20 a small conical cavity 21. The grooves 14 allow, during the placement of the implant to evacuate bone dust, blood, etc.
Après la pose de l'implant on ferme l'extrémité libre de celui ci, qui fait saillie à la surface de la gencive avec une résine qui vient jusque dans la cavité tronconique 21. After the implant is placed, the free end of the implant is closed, which protrudes from the surface of the gum with a resin which comes into the frustoconical cavity 21.
Un tel implant peut être réalisé en titane puret constitue une racine artificielle permettant par sa partie en sàillie de former un support, sur lequel on peutmettre en place une prothèse telle qu'une couronne, un bridge. On peut également utiliser un tel implant pour une prothèse amovible telle qu'un dentier partiel ou entier. Such an implant can be made of pure titanium constitutes an artificial root allowing, by its protruding part, to form a support, on which a prosthesis such as a crown, a bridge can be put in place. One can also use such an implant for a removable prosthesis such as a partial or whole denture.
Lorsque l'implant est posé, il peut déja recevoir la prothèse et dans le temps, il s'inclut @tièrement da@s l'os qui en se reformant passe à travers les ouvertures 5, 6, 7 et 8. When the implant is placed, it can already receive the prosthesis and over time, it is completely included in the bone which, when reformed, passes through the openings 5, 6, 7 and 8.
On peut aussi utiliser un tel implant pour permettre une reconstitution après fracture. One can also use such an implant to allow a reconstruction after fracture.
Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être decrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir, pour celaodu cadre de l'invention. Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of detail can be made without departing, for this purpose from the scope of the invention.
