Definitions
- the present invention relates to a toothbrush comprising a handle of substantially rectangular section and a head furnished with a tuft of bristles substantially tangent to one another.
- Toothbrushes of the type defined above are known from documents US-A-3,754,295 and EP-A-60,592.
- Periodontopathies such as gingivitis
- the present invention relates to a brush defined above arranged so as to allow not only the removal of the bacterial plaque which covers the surface of the teeth, but also a massage at the level of the non-keratinized sulcular gum and the epithelium of junction.
- the toothbrush according to the present invention allows the removal of bacterial plaque from the entire surface (non-chewing and chewing) of the teeth, including the surface at the level of the sulcular gum and the intermediate surface, as well as a brushing and massage of the sulcus gum ensuring keratinization of the latter.
- the toothbrush according to the invention differs from conventional toothbrushes, as much by the dimensions and the shape of the tufts of bristles as by the shape and the dimensions of the head carrying these tufts of bristles, as well as by the shape and the dimensions of the handle to which the head is connected, these differences making it possible to obtain a toothbrush offering the advantages mentioned in the previous paragraph, thanks to a mode of use radically different from that of conventional toothbrushes, as will be seen more far.
- the toothbrush of the type defined in the first paragraph of this specification is essentially characterized in that its head has a circular or elliptical cross section, the diameter or width of which is less than the width of the handle, in that the bristles the tuft have a length, relative to the head, of about 10 to 15 mm and in that the width of the tuft of bristles is about 0.5 to 3 mm.
- the width of the single tuft of hair corresponds substantially to the depth of the sulcus groove.
- the hairs of the tuft are inserted into an elongated window passing right through the head from one face of the latter to its opposite face, this latter face revealing the end of the hairs welded together and having capillary conduits between them.
- the characteristic shapes and dimensions of the toothbrush according to the invention can be used in a completely different way from that of conventional brushes.
- the teeth are brushed using the free ends of the bristles in an alternating movement.
- the brush according to the present invention is eminently suitable for use according to an original technique allowing the ends of the bristles to penetrate to the bottom of the sulcus groove, between the gingival crest and the teeth, so as to ensure a gentle massage of the internal surface of the gingival gum and to favor the homogeneous appearance of a protective keratinization of this surface. Furthermore, the tangent bristles of the brush according to the invention are used for scraping by their lateral surface, rather than brushing by their ends, the lateral surface of the teeth.
- the brush according to the invention comprises a handle 1 ending in a head 2 carrying a single tuft comprising a multitude of bristles 3 projecting with respect to a face 4 of the head 2 and tangents l to one another.
- the handle 1 of the brush can be inclined or curved so that the head 2 carrying the bristles 3 is at a level lower than that the handle or part of it, when the brush is placed on a surface with its bristles pointing upwards.
- This arrangement favors the access of the hairs to the teeth, especially on the lingual side of the dental crown.
- the tuft of bristles 3 may comprise, for example, one thousand two hundred rigid monofilamentary hairs or strands, for example made of nylon, with a diameter of 0.22 millimeters, forming a dense tuft, the width La of which corresponds substantially to the depth of the sulcus sulcus, this depth being about 0.5 to 3 millimeters.
- the bristles preferably have an identical length and protrude relative to the head 2 over a distance at least equal to the maximum average height of the teeth, ie in practice a length L o of 10 to 15 millimeters.
- the free ends of the bristles form a flat surface, this surface however being able to be slightly convex and concave.
- the surface formed by the free ends of the hairs is dense and free of protruding hairs and roughness.
- the length L o of the tuft of bristles 3 is not critical. It can vary, for example, between 15 and 25 millimeters.
- the tuft of bristles 3 is inserted into a window 5 pierced right through in the head 2 of the face 4 of the latter to its opposite face 6. This face 6 reveals the end of the bristles welded together and having hundreds of capillary conduits.
- the free ends of the individual hairs preferably have the shape of a rounded head, such as a mushroom head.
- the head 2 has a circular cross section over its entire length and is connected at 8 to a handle 1 having a rectangular cross section.
- the diameter of the head 2 is preferably about 3 to 5 millimeters.
- the head 2 can have an elliptical cross section.
- the handle 1 has a square cross section.
- the median longitudinal plane, shown diagrammatically by the dashed line P 1 in FIG. 2, of the tuft of hairs 3 makes an angle of 45 °, with the plane P 2 of at least one face of the handle turned towards the end free from the tuft of hairs 3.
- the plane P 1 is a bisector plane making an angle a of 45 ° with the planes P ⁇ , P 3 of two symmetrical faces 9 and 10 of its handle 1 of square cross section, facing the free end of the tuft of bristles 3.
- the plane P i also contains the opposite edges 11 and 12 of the handle 1.
- the user has a secure means of properly orienting the tuft of bristles 3 when it takes the brush in hand.
- the user when the user is right-handed and wants to brush the lower teeth, he places the thumb of his right hand on face 10, while when he is left-handed, he applies the thumb of his left hand to the side 9 of the handle.
- the handle 1 is held in the right hand in this way, the tuft of bristles 3 is oriented, so as to allow the use of the brush according to the technique described below which is entirely different from the conventional mode or modes use of known toothbrushes.
- the head 2 and the tuft of bristles 3 of the compact sulcular brush according to the invention have dimensions much smaller than those of conventional brushes.
- the brush according to the invention in particular that illustrated in FIGS. 1 and 2, can be used according to a technique making it possible to dislodge the plate. bacterial as well as the desquamated cells of the junctional and sulcular gum, while allowing scraping of the vestibular and lingual surfaces of the teeth.
- FIGS. 3 to 5 The technique of using the brush according to the invention is illustrated in FIGS. 3 to 5.
- the brush is arranged so that its bristles 3 extend parallel to the vestibular or lingual surface of the dental crown, that is to say so that the bristles, at their free end, are tangent to the lateral surface of the teeth 13 at their collar 14. Thanks to the reduced width (0.5 to 3 millimeters) of the tuft of hairs 3, the free ends 15 of the hairs penetrate into the groove sulcular 16 between the gingival crest 17 and the teeth 13. While the free ends 15 of the bristles are in contact with the bottom of the sulcular sulcus, the lateral surface of the bristles is applied to the vestibular or lingual lateral surface of the dental crown, marrying, as shown in Figure 3, the sinuous shape of this crown.
- the head 2 of the brush is then subjected to a low amplitude vibratory back-and-forth movement in the direction of the arrows Y, so that the free ends 15 of the bristles 3 pressed into the gingival groove 16 provide massage and a scraping from the inside of this gingival groove 16, while the bristles 3 sweep through their lateral surface the lateral vestibular or lingual surface of the dental crown.
- FIG. 5 shows the sinuous movement which the bristles 3 take in scraping by their lateral surface the coronal surface of the teeth, while the free ends 15 of the bristles massage the gingival groove 16.
- the bristles 3 of the brush according to the invention extend parallel to this lateral surface.
- the free ends 15 of the bristles 3 pressed into the gingival groove 16 undergo almost no displacement in this groove and simply massage the gingival and papillary sulcus. Thanks to this massage and the capillary effect created by the tangent hairs one at a tre, there is an aspiration of the bacterial plaque from the inside of the gingival groove 16 towards the dorsal face 6 of the head 2 of the brush, while the surface of the crown and the collar of the teeth 13 is cleaned by the face lateral hair that sweeps across this surface.
- the above-described use technique of the brush according to the invention allows perfect elimination of the bacterial plaque contained in the gingival groove and a cleaning of the coronal surface and the neck of the teeth, without gum irritation, without risk of scratching or abrasion of the coronal surface and the neck of the teeth and without pressure being exerted by the keratinized part of the gum on the tooth (which avoids any risk of gingival recession).
- Massage of the internal surface of the gingival groove by the free ends 15 of the bristles 3 promotes homogeneous keratinization ensuring protection of the cell layer of this internal surface.
- the shape and dimensions of the head 2 of the compact sulcular brush according to the invention make it practically impossible any brushing liable to cause gingival lesions and other lesions in the mouth of the user.

Description
La présente invention est relative à une brosse à dents comportant un manche de section sensiblement rectangulaire et une tête garnie d'une touffe de poils sensiblement tangents l'un à l'autre.The present invention relates to a toothbrush comprising a handle of substantially rectangular section and a head furnished with a tuft of bristles substantially tangent to one another.
On connaît des brosses à dents du type défini ci-avant par les documents US-A-3 754 295 et EP-A-60 592.Toothbrushes of the type defined above are known from documents US-A-3,754,295 and EP-A-60,592.
Les études cliniques et histologiques ont montré que les parodontopathies, telles que la gingivite, apparaissent non pas au niveau de la partie de la gencive qui est kératinisée, mais bien au niveau du sulcus gingival non kératinisé.Clinical and histological studies have shown that periodontopathies, such as gingivitis, appear not at the part of the gum that is keratinized, but at the level of the non-keratinized gingival sulcus.
La présente invention a pour objet une brosse définie plus haut agencée de manière à permettre non seulement l'enlèvement de la plaque bactérienne qui recouvre la surface des dents, mais également un massage au niveau de la gencive sulculaire non kératinisée et de l'épithélium de jonction. Ainsi, la brosse à dents suivant la présente invention permet l'élimination de la plaque bactérienne de toute la surface (non mastiquante et mastiquante) des dents, y compris la surface au niveau de la gencive sulculaire et la surface intermédiaire, ainsi qu'un brossage et un massage de la gencive sulculaire assurant une kératinisation de celle-ci.The present invention relates to a brush defined above arranged so as to allow not only the removal of the bacterial plaque which covers the surface of the teeth, but also a massage at the level of the non-keratinized sulcular gum and the epithelium of junction. Thus, the toothbrush according to the present invention allows the removal of bacterial plaque from the entire surface (non-chewing and chewing) of the teeth, including the surface at the level of the sulcular gum and the intermediate surface, as well as a brushing and massage of the sulcus gum ensuring keratinization of the latter.
La brosse à dents suivant l'invention se différencie des brosses à dents classiques, tant par les dimensions et la forme des touffes de poils que par la forme et les dimensions de la tête portant ces touffes de poils, ainsi que par la forme et les dimensions du manche auquel la tête est reliée, ces différences permettant d'obtenir une brosse à dents offrant les avantages mentionnés dans le paragraphe précédent, grâce à un mode d'utilisation radicalement différent de celui des brosses à dents classiques, comme on le verra plus loin.The toothbrush according to the invention differs from conventional toothbrushes, as much by the dimensions and the shape of the tufts of bristles as by the shape and the dimensions of the head carrying these tufts of bristles, as well as by the shape and the dimensions of the handle to which the head is connected, these differences making it possible to obtain a toothbrush offering the advantages mentioned in the previous paragraph, thanks to a mode of use radically different from that of conventional toothbrushes, as will be seen more far.
La brosse à dents du type défini dans le premier paragraphe du présent mémoire est essentiellement caractérisée en ce que sa tête présente une section transversale circulaire ou elliptique, dont le diamètre ou la largeur est inférieur à la largeur du manche, en ce que les poils de la touffe ont une longueur, par rapport à la tête, d'environ 10 à 15 mm et en ce que la largeur de la touffe de poils est d'environ 0,5 à 3 mm.The toothbrush of the type defined in the first paragraph of this specification is essentially characterized in that its head has a circular or elliptical cross section, the diameter or width of which is less than the width of the handle, in that the bristles the tuft have a length, relative to the head, of about 10 to 15 mm and in that the width of the tuft of bristles is about 0.5 to 3 mm.
Selon une particularité de l'invention, la largeur de l'unique touffe de poils correspond sensiblement à la profondeur du sillon sulculaire.According to a feature of the invention, the width of the single tuft of hair corresponds substantially to the depth of the sulcus groove.
Selon une autre particularité de l'invention, les poils de la touffe sont insérés dans une fenêtre allongée traversant de part en part la tête d'une face de celle-ci à sa face opposée, cette dernière face laissant apparaître l'extrémité des poils soudés entre eux et présentant des conduits capillaires entre eux.According to another feature of the invention, the hairs of the tuft are inserted into an elongated window passing right through the head from one face of the latter to its opposite face, this latter face revealing the end of the hairs welded together and having capillary conduits between them.
Grâce aux formes et dimensions caractéristiques de la brosse à dents suivant l'invention, celle-ci peut être utilisée d'une manière totalement différente de celle des brosses classiques.Thanks to the characteristic shapes and dimensions of the toothbrush according to the invention, it can be used in a completely different way from that of conventional brushes.
Lors de l'utilisation des brosses classiques, on brosse les dents à l'aide des extrémités libres des poils suivant un mouvement alternatif.When using conventional brushes, the teeth are brushed using the free ends of the bristles in an alternating movement.
Ce mode d'utilisation des brosses à dents classiques empêche d'atteindre certaines surfaces difficilement accessibles, en sorte que l'élimination de la plaque bactérienne y est mal assurée et que l'apparition de parodontopathies récidivantes n'y est pas convenablement empêchée. La conformation et le mode d'utilisation des brosses à dents classiques ne permettent, par ailleurs, qu'une pénétration médiocre et irrégulière des poils dans le sulcus gingival, en sorte que l'élimination de la plaque bactérienne et que la disparition de parodontopathies dans ce sulcus ne sont pas assurées.This mode of use of conventional toothbrushes prevents certain hard-to-reach surfaces from being reached, so that the elimination of bacterial plaque is poorly ensured and that the appearance of recurrent periodontopathies is not properly prevented there. The conformation and the mode of use of the classic toothbrushes allow, moreover, only a mediocre and irregular penetration of the hairs in the gingival sulcus, so that the elimination of the bacterial plate and that the disappearance of periodontopathies in this sulcus is not insured.
La brosse suivant la présente invention convient éminemment pour être utilisée suivant une technique originale permettant aux extrémités des poils de pénétrer jusqu'au fond du sillon sulculaire, entre la crête gingivale et les dents, de manière à assurer un massage doux de la surface interne de la gencive gingivale et à favoriser l'apparition homogène d'une kératinisation protectrice de cette surface. Par ailleurs, les poils tangents de la brosse suivant l'invention sont utilisés pour racler par leur surface latérale, plutôt que de brosser par leurs extrémités, la surface latérale des dents.The brush according to the present invention is eminently suitable for use according to an original technique allowing the ends of the bristles to penetrate to the bottom of the sulcus groove, between the gingival crest and the teeth, so as to ensure a gentle massage of the internal surface of the gingival gum and to favor the homogeneous appearance of a protective keratinization of this surface. Furthermore, the tangent bristles of the brush according to the invention are used for scraping by their lateral surface, rather than brushing by their ends, the lateral surface of the teeth.
D'autres particularités et détails de l'invention ressortiront de la description suivante des dessins ci-annexés qui montrent schématiquement une forme de réalisation d'une brosse à dents suivant l'invention, ainsi que la technique d'utilisation de celle-ci.Other particularities and details of the invention will emerge from the following description of the appended drawings which schematically show an embodiment of a toothbrush according to the invention, as well as the technique for using it.

Dans ces différentes figures, les mêmes notations de référence désignent des éléments identiques.In these different figures, the same reference notations designate identical elements.
La brosse suivant l'invention, représentée à la figure 1 des dessins, comprend un manche 1 se terminant par une tête 2 portant une seule touffe comprenant une multitude de poils 3 faisant saillie par rapport à une face 4 de la tête 2 et tangents l'un à l'autre.The brush according to the invention, represented in FIG. 1 of the drawings, comprises a
Au lieu de s'étendre dans le prolongement de la tête 2, comme montré à la figure 1, le manche 1 de la brosse peut être incliné ou courbé de telle sorte que la tête 2 portant les poils 3 soit à un niveau inférieur à celui du manche ou d'une partie de celui-ci, lorsque la brosse est posée sur une surface en ayant ses poils dirigés vers le haut. Cette disposition favorise l'accès des poils aux dents, en particulier du côté lingual de la couronne dentaire.Instead of extending in the extension of the
La touffe de poils 3 peut comporter, par exemple, mille deux cents poils ou brins monofilamen- taires rigides, par exemple en nylon, d'un diamètre de 0,22 millimètre, formant une touffe dense, dont la largeur La correspond sensiblement à la profondeur du sillon sulculaire, cette profondeur étant d'environ 0,5 à 3 millimètres.The tuft of
Les poils ont, de préférence, une longueur identique et font saillie par rapport à la tête 2 sur une distance au moins égale à la hauteur maximale moyenne des dents, soit en pratique une longueur Lo de 10 à 15 millimètres. Les extrémités libres des poils forment une surface plane, cette surface pouvant cependant être légèrement convexe et concave. La surface formée par les extrémités libres des poils est dense et exempte de poils saillants et d'aspérités. La longueur L'o de la touffe de poils 3 n'est pas critique. Elle peut varier, par exemple, entre 15 et 25 millimètres.The bristles preferably have an identical length and protrude relative to the
La touffe de poils 3 est insérée dans une fenêtre 5 percée de part en part dans la tête 2 de la face 4 de celle-ci à sa face opposée 6. Cette face 6 laisse apparaître l'extrémité des poils soudés entre eux et présentant des centaines de conduits capillaires.The tuft of
Les extrémités libres des poils individuels ont, de préférence, la forme d'une tête arrondie, telle qu'une tête de champignon.
La tête 2 présente une section transversale circulaire sur toute sa longueur et est raccordée en 8 à un manche 1 ayant une section transversale rectangulaire. Le diamètre de la tête 2 est, de préférence, d'environ 3 à 5 millimètres.The free ends of the individual hairs preferably have the shape of a rounded head, such as a mushroom head.
The
Au lieu d'avoir une section transversale circulaire, la tête 2 peut avoir une section transversale elliptique.Instead of having a circular cross section, the
Aux figures 1 et 2, le manche 1 présente une section transversale carrée.In Figures 1 and 2, the
Le plan longitudinal médian, schématisé par la ligne en traits mixtes P1 à la figure 2, de la touffe de poils 3 fait un angle de 45°, avec le plan P2 d'au moins une face du manche tournée vers l'extrémité libre de la touffe de poils 3. Comme on le voit à la figure 2, le plan P1 est un plan bissecteur faisant un angle a de 45° avec les plans Pε, P3 de deux faces symétriques 9 et 10 de son manche 1 de section transversale carrée, tournées vers l'extrémité libre de la touffe de poils 3. Le plan Pi contient, par ailleurs, les arêtes opposées 11 et 12 du manche 1.The median longitudinal plane, shown diagrammatically by the dashed line P 1 in FIG. 2, of the tuft of
Grâce à l'angle a précité entre les plans P2, P3 des faces 9 et 10 du manche 1 et le plan longitudinal médian P1 de la touffe de poils 3, l'utilisateur dispose d'un moyen sûr pour orienter convenablement la touffe de poils 3 lorsqu'il prend la brosse en main. Ainsi, lorsque l'utilisateur est droitier et qu'il désire brosser les dents du bas, il pose le pouce de la main droite sur la face 10, tandis que lorsqu'il est gaucher, il applique le pouce de la main gauche sur la face 9 du manche. Lorsque le manche 1 est tenu en main droite de cette façon, la touffe de poils 3 est orientée, de façon à permettre l'utilisation de la brosse selon la technique décrite plus loin qui est tout-à-fait différente du ou des modes classiques d'utilisation des brosses à dents connues.Thanks to the aforementioned angle between the planes P 2 , P 3 of the
La tête 2 et la touffe de poils 3 de la brosse sulculaire compacte suivant l'invention ont des dimensions largement inférieures à celles des brosses classiques.The
Grâce à la conformation et aux dimensions de la tête 2 de la touffe de poils 3 et du manche 1, la brosse suivant l'invention, en particulier celle illustrée aux figures 1 et 2, peut être utilisée selon une technique permettant de déloger la plaque bactérienne ainsi que les cellules desquamées de la gencive jonctionnelle et sulculaire, tout en permettant un raclage des surfaces vestibulaire et linguale des dents.Thanks to the conformation and the dimensions of the
La technique d'utilisation de la brosse suivant l'invention est illustrée aux figures 3 à 5.The technique of using the brush according to the invention is illustrated in FIGS. 3 to 5.
Comme on le voit à la figure 3, la brosse est disposée de façon que ses poils 3 s'étendent parallèlement à la surface vestibulaire ou linguale de la couronne dentaire, c'est-à-dire de façon que les poils, au niveau de leur extrémité libre, soient tangents à la surface latérale des dents 13 au niveau de leur collet 14. Grâce à la largeur réduite (0,5 à 3 millimètres) de la touffe de poils 3, les extrémités libres 15 des poils pénètrent dans le sillon sulculaire 16 entre la crête gingivale 17 et les dents 13. Tandis que les extrémités libres 15 des poils sont en contact avec le fond du sillon sulculaire, la surface latérale des poils est appliquée sur la surface latérale vestibulaire ou linguale de la couronne dentaire, en épousant, comme le montre la figure 3, la forme sinueuse de cette couronne. Lorsque la tête 2 et la touffe de poils 3 sont dans la position montrée aux figures 3 et 4, dans laquelle la tête 2 est parallèle au plan acclusal X, on exerce une pression sur la tête 2 vers le centre des dents. De cette façon, les poils 3 se disposent régulièrement tout le long du sillon gingival 16, en suivant le pourtour du collet 14 des dents 13 jusqu'à l'espace interdentaire. On soumet ensuite la tête 2 de la brosse à un mouvement de va-et-vient vibratoire de faible amplitude dans le sens des flèches Y, de façon que les extrémités libres 15 des poils 3 enfoncées dans le sillon gingival 16 assurent un massage et un raclage de l'intérieur de ce sillon gingival 16, tandis que les poils 3 balayent par leur surface latérale la surface latérale vestibulaire ou linguale de la couronne dentaire.As seen in Figure 3, the brush is arranged so that its
La figure 5 montre le mouvement sinueux que les poils 3 prennent en raclant par leur surface latérale la surface coronnaire des dents, tandis que les extrémités libres 15 des poils massent le sillon gingival 16.FIG. 5 shows the sinuous movement which the
On voit ainsi qu'au lieu d'être dirigés vers la surface latérale des dents, les poils 3 de la brosse suivant l'invention s'étendent parallèlement à cette surface latérale. En fait, les extrémités libres 15 des poils 3 enfoncées dans le sillon gingival 16 ne subissent quasiment pas de déplacement dans ce sillon et massent simplement le sulcus gingival et papillaire. Grâce à ce massage et à l'effet de capillarité créé par les poils tangents l'un à l'autre, il se produit une aspiration de la plaque bactérienne depuis l'intérieur du sillon gingival 16 vers la face dorsale 6 de la tête 2 de la brosse, tandis que la surface de la couronne et du collet des dents 13 est nettoyée par la face latérale des poils qui balaye cette surface.It can thus be seen that instead of being directed towards the lateral surface of the teeth, the
La technique d'utilisation susdécrite de la brosse suivant l'invention permet une élimination parfaite de la plaque bactérienne contenue dans le sillon gingival et un nettoyage de la surface coronnaire et du collet des dents, sans irritation gingivale, sans risque de griffage ou d'abrasion de la surface coronnaire et du collet des dents et sans qu'une pression soit exercée par la partie kératinisée de la gencive sur la dent (ce qui évite tout risque de récession gingivale). Le massage de la surface interne du sillon gingival par les extrémités libres 15 des poils 3 favorise une kératinisation homogène assurant une protection de la couche cellulaire de cette surface interne.The above-described use technique of the brush according to the invention allows perfect elimination of the bacterial plaque contained in the gingival groove and a cleaning of the coronal surface and the neck of the teeth, without gum irritation, without risk of scratching or abrasion of the coronal surface and the neck of the teeth and without pressure being exerted by the keratinized part of the gum on the tooth (which avoids any risk of gingival recession). Massage of the internal surface of the gingival groove by the free ends 15 of the
La forme et les dimensions de la tête 2 de la brosse sulculaire compacte suivant l'invention rendent pratiquement impossible tout brossage susceptible de causer des lésions gingivales et d'autres lésions dans la bouche de l'utilisateur.The shape and dimensions of the
