Description

Implant dentaire à connecteur tronconique femelle Dental implant with female frustoconical connector
La présente invention se rapporte à un implant dentaire à connecteur tronconique femelle.The present invention relates to a dental implant with female frustoconical connector.
La présente invention se rapporte plus particulièrement aux moyens de raccordement entre l'embase d'ancrage de l'implant et le pilier de support de la dent prothétique.The present invention relates more particularly to connection means between the anchor base of the implant and the support pillar of the prosthetic tooth.
II existe déjà de nombreux implants comprenant une embase d'ancrage indépendante pourvue de moyens de raccordement avec la dent prothétique.There are already numerous implants comprising an independent anchoring base provided with connection means with the prosthetic tooth.
Cependant, ces moyens de raccordement ne permettent pas d'assurer un niveau d'étanchéité suffisant entre l'implant et le pilier ce qui pose des problèmes de contamination bactériologique de l'espace biologique situé à la jonction entre l'implant, l'os et la gencive.However, these connection means do not ensure a sufficient level of sealing between the implant and the pillar which poses problems of bacteriological contamination of the biological space at the junction between the implant, the bone and the gum.
Or Cette contamination est susceptible de provoquer des inflammations de la gencive ainsi que des phénomènes de résorption osseuse.Gold This contamination is likely to cause inflammation of the gums and bone resorption phenomena.
En outre, ces moyens de raccordement ne permettent pas d'assurer un report optimal des contraintes mécaniques sur l'ensemble de l'implant.In addition, these connection means do not ensure an optimal transfer of mechanical stresses on the entire implant.
Cette déficience est susceptible d'entraîner des problèmes d'ostéointégration et de conduire à un échec d'implantation.This deficiency is likely to lead to osseointegration problems and lead to implant failure.
II existe des implants avec des moyens de raccordement sous forme de connecteurs femelles.There are implants with connection means in the form of female connectors.
Toutefois, ces connecteurs soit ne permettent pas l'indexation des surfaces prothétiques ce qui pose des problèmes de positionnement et de manipulation soit ne peuvent assurer un report optimum des contraintes.However, these connectors either do not allow the indexing of the prosthetic surfaces which poses problems of positioning and manipulation or can not ensure an optimal postponement of the constraints.
La présente invention entend résoudre ces problèmes techniques de manière efficace et satisfaisante.The present invention aims to solve these technical problems effectively and satisfactorily.
Dans cet objectif, l'implant de la présente invention est caractérisé en ce que lesdits moyens de raccordement comprennent une cavité tronconique interne ménagée dans la partie supérieure de l'embase dont le pourtour extérieur est muni d'un bord périphérique chanfreiné et le pourtour intérieur, d'un relief d'indexation et qui est destinée à recevoir, par emboîtement, la base homothétique dudit pilier.For this purpose, the implant of the present invention is characterized in that said connecting means comprise an internal frustoconical cavity arranged in the upper part of the base whose outer periphery is provided with a chamfered peripheral edge and the inner periphery, an indexing relief and which is intended to receive, by interlocking, the homothetic base of said pillar.
Selon une caractéristique avantageuse, ladite cavité se prolonge vers le bas par un taraudage axial destiné à recevoir une vis de fixation dudit pilier.According to an advantageous characteristic, said cavity is extended downwards by an axial tapping intended to receive a fixing screw of said pillar.
Selon une variante spécifique, ledit relief d'indexation est constitué de facettes latérales délimitant un hexagone.According to a specific variant, said indexing relief consists of lateral facets delimiting a hexagon.
Selon une autre caractéristique, la paroi de la cavité est séparée longitudinalement du relief d'indexation par une rainure circulaire.According to another characteristic, the wall of the cavity is separated longitudinally from the indexing relief by a circular groove.
Selon encore une autre caractéristique, ladite embase comporte une collerette supérieure lisse prolongeant extérieurement le rebord chanfreiné vers le basAccording to yet another characteristic, said base comprises a smooth upper collar extending externally chamfered flange downwards.
De préférence, ladite collerette présente des génératrices cylindriques et surmonte des portions filetées successivement conique et cylindrique de l'embase dont les diamètres externes sont continus.Preferably, said collar has cylindrical generatrices and overcomes successively conical and cylindrical threaded portions of the base whose external diameters are continuous.
Selon une variante particulière, l'angle du cône de ladite cavité est compris entre 7° et 9°.According to a particular variant, the angle of the cone of said cavity is between 7 ° and 9 °.
Selon une autre variante, ladite embase porte un triple filetage.According to another variant, said base carries a triple thread.
Selon un mode de réalisation avantageux de l'implant, le pilier comporte une tête élargie présentant un épaulement inférieur.According to an advantageous embodiment of the implant, the pillar comprises an enlarged head having a lower shoulder.
Le cas échéant cet épaulement pourra reposer sur le rebord périphérique de ladite embase.If necessary this shoulder may rest on the peripheral rim of said base.
De préférence, ledit pilier est pourvu d'un alésage interne traversant dans lequel est logée une vis de fixation L'implant de l'invention permet de garantir une parfaite étanchéité de la liaison embase/pilier, un transfert de charges optimisé et une bonne répartition des contraintes.Preferably, said pillar is provided with a through internal bore in which is housed a fixing screw The implant of the invention makes it possible to guarantee perfect sealing of the base / pillar connection, optimized charge transfer and a good distribution of stresses.
La fixation du pilier dans l'embase est suffisamment forte tout en étant réversible pour éviter les désolidarisations intempestives de la dent prothétique et assure un centrage très précis de l'assemblage.Fixing the abutment in the base is strong enough while being reversible to prevent untimely disconnections of the prosthetic tooth and ensures a very accurate centering of the assembly.
Le positionnement du pilier est indexé de façon précise sur les moyens de raccordement de l'implant ce qui permet un ajustement optimum de la dent prothétique dans son logement.The positioning of the abutment is accurately indexed to the connection means of the implant which allows an optimum fit of the prosthetic tooth in its housing.
En outre, l'efficacité et la précision des moyens d'indexation de l'invention favorise les manipulations des surfaces prothétiques lors des transferts d'information entre le chirurgien et le prothésiste.In addition, the efficiency and accuracy of the indexing means of the invention promotes manipulation of the prosthetic surfaces during information transfers between the surgeon and the prosthetist.
Enfin, l'absence de relargage bactériologique permet de préserver un espace biologique neutre et sain pour la cicatrisation gingivale et d'obtenir, par conséquent, un résultat esthétique optimal.Finally, the absence of bacteriological release allows to preserve a neutral and healthy biological space for the gingival cicatrization and to obtain, consequently, an optimal esthetic result.
L'invention sera mieux comprise à l'aide de la description, ci-après, faite à titre purement explicatif, d'un mode de réalisation de l'invention, en référence aux figures annexées sur lesquelles:The invention will be better understood from the following description, given purely for explanatory purposes, of an embodiment of the invention, with reference to the appended figures in which:
- la figure 1 représente une vue de profil en éclaté d'un mode de réalisation de l'implant de l'invention ; les figures 2A et 2B représentent respectivement des vues de profil et en coupe selon M-Il de l'embase de la figure 1 ; la figure 3 illustre une vue de dessus de l'embase de la figure 1 et ; - la figure 4 illustre une vue de détail en coupe de l'embase illustrée sur la figure 2.FIG. 1 represents an exploded side view of an embodiment of the implant of the invention; FIGS. 2A and 2B show respectively sectional and sectional views along M-II of the base of FIG. 1; Figure 3 illustrates a top view of the base of Figure 1 and; FIG. 4 illustrates a detail view in section of the base illustrated in FIG. 2.
L'implant de l'invention est représenté sur la figure 1.The implant of the invention is shown in FIG.
Cet implant comprend une embase 1 , un pilier 2 de support d'une dent prothétique (non représentée) et une vis de fixation 3. L'embase 1 utilisée pour l'ancrage de l'implant selon l'invention dans une zone osseuse de la mâchoire, est plus particulièrement illustrée sur les figures 2A et 2B.This implant comprises a base 1, a pillar 2 for supporting a prosthetic tooth (not shown) and a fixing screw 3. The base 1 used for anchoring the implant according to the invention in a bone zone of the jaw is more particularly illustrated in FIGS. 2A and 2B.
Cette embase est pourvue de moyens de raccordement au pilier de support de la dent prothétique.This base is provided with connection means to the support pillar of the prosthetic tooth.
Ces moyens de raccordement comprennent une cavité tronconique interne 10 ménagée dans la partie supérieure de l'embase 1 et dont le pourtour extérieur est muni d'un bord périphérique chanfreiné 11.These connection means comprise an internal frustoconical cavity 10 formed in the upper part of the base 1 and whose outer periphery is provided with a chamfered peripheral edge 11.
La cavité 10 est destinée à recevoir, par emboîtement, la base homothétique 20 du pilier de la dent prothétique.The cavity 10 is intended to receive, by interlocking, the homothetic base 20 of the abutment of the prosthetic tooth.
La cavité 10 peut être réalisée dans un élément rapporté qui est lui-même fixé à l'intérieur d'un alésage de l'embase ou directement ménagée dans l'embase.The cavity 10 may be made in an insert which is itself fixed inside a bore of the base or directly formed in the base.
La profondeur de la cavité 10 est d'environ 2,5 mm pour des hauteurs d'embase comprises entre 6 et 19 mm selon les calibres des dents à poser.The depth of the cavity 10 is about 2.5 mm for base heights between 6 and 19 mm depending on the calibres of the teeth to be laid.
L'angle du cône de la cavité 10 et donc de la base 20 du pilier est compris entre 7° et 9°.The angle of the cone of the cavity 10 and therefore of the base 20 of the pillar is between 7 ° and 9 °.
Le pourtour intérieur de la cavité 10 est pourvu, ici en partie basse, d'un relief d'indexation 12 représenté sur la figure 2B.The inner periphery of the cavity 10 is provided, here at the bottom, with an indexing relief 12 shown in FIG. 2B.
