Description
La présente invention concerne le domaine des brosses à dents.The present invention relates to the field of toothbrushes.
La présente invention concerne plus précisément une brosse à dents orthodontique destinée à être utilisée tout particulièrement par les enfants portant des verrous redresseurs.The present invention relates more specifically to an orthodontic toothbrush intended to be used in particular by children wearing rectifier locks.
On sait que les techniques dites d'orthodontie et d'orthopédie dentofaciale qui utilisent les thérapeutiques fixes, visant à corriger les déformations de la denture, sont maintenant utilisées fréquemment chez les enfants.It is known that the techniques known as orthodontics and dentofacial orthopedics which use fixed therapies, aimed at correcting the deformations of the teeth, are now frequently used in children.
Ces thérapeutiques fixes font appel à des moyens d'ancrage, que l'on désignera ici sous le vocable de verrous redresseurs, fixés sur les dents, et à des arcs, généralement métalliques, qui passent dans les verrous et sont adaptés pour déplacer les dents.These fixed therapies call on anchoring means, which will be designated here by the term of straightening locks, fixed on the teeth, and on arcs, generally metallic, which pass through the locks and are adapted to move the teeth. .
Les moyens d'ancrage précités peuvent être soit collés directement sur les dents (plus précisément sur les couronnes dentaires), soit rendus solidaires de bagues fixées sur les dents.The abovementioned anchoring means can either be bonded directly to the teeth (more precisely on the dental crowns), or made integral with rings fixed to the teeth.
Toutes ces adjonctions sur les dents font que, dans la pratique, la plaque bactérienne responsable des caries est plus difficile à éliminer.All these additions to the teeth make it, in practice, the bacterial plaque responsible for cavities more difficult to remove.
Contrairement à une idée parfois développée, ce ne sont pas les bagues ni les verrous redresseurs qui provoquent les caries dentaires.Contrary to an idea sometimes developed, it is not the rings or the straightening locks that cause tooth decay.
Celles-ci résultent seulement de la difficulté du brossage dentaire pendant les traitements d'orthodontie, due à la présence des verrous redresseurs et des arcs.These only result from the difficulty of brushing teeth during orthodontic treatments, due to the presence of straightening latches and arches.
Bien que de nombreux types de brosses à dents aient déjà été proposés, aucune des brosses disponibles à ce jour sur le marché n'a permis de résoudre le problème ainsi posé.Although many types of toothbrushes have already been proposed, none of the brushes available to date on the market has solved the problem thus posed.
Les praticiens ont tenté de limiter le développement de caries dentaires chez les enfants porteurs de verrous redresseurs en conseillant à ces enfants, d'utiliser, en plus de la brosse usuelle, des jets dentaires qui projettent de l'eau sous pression sur et entre les dents.Practitioners have attempted to limit the development of dental caries in children with locks straighteners advising these children to use, in addition to the usual brush, dental jets which spray water under pressure on and between the teeth.
Néanmoins, ces jets dentaires, si ils évacuent les gros débris alimentaires restés entre les dents, ne permettent pas de retirer la plaque bactérienne qui ne peut être éliminée par le brossage et qui est, comme indiqué précédemment, responsable de l'apparition des caries dentaires.However, these dental jets, if they evacuate the large food debris left between the teeth, do not make it possible to remove the bacterial plaque which cannot be removed by brushing and which is, as indicated previously, responsible for the appearance of dental caries .
On connait déjà, par ailleurs, par le brevet US-3 978 852, une brosse à dents électromécanique (vibrante) dont la tête porte des touffes de poils pointues, adaptées pour se loger dans les interstices interdentaires ainsi que, le cas échéant, sous les arcs des verrous redresseurs. Le brossage des espaces accessibles aux touffes est obtenu par un mouvement de va-et-vient de la tête de brossage suivant une direction parallèle aux poils. Un tel arrangement n'est donc pas utilisable pour une brosse à dents manuelle, dont le mouvement de brossage se fait suivant une direction sensiblement perpendiculaire aux poils.We already know, moreover, by patent US-3 978 852, an electromechanical (vibrating) toothbrush whose head carries tufts of pointed bristles, adapted to be housed in the interdental interstices as well as, if necessary, under the arcs of the rectifier locks. The brushing of the spaces accessible to the tufts is obtained by a back and forth movement of the brushing head in a direction parallel to the bristles. Such an arrangement cannot therefore be used for a manual toothbrush, the brushing movement of which takes place in a direction substantially perpendicular to the bristles.
On connait également, par le brevet FR-830 801,une brosse à dents qui présente une tête de brossage munie de plusieurs rangées de touffes de poils - ou loquets - dont certaines sont inclinées vers l'extérieur et d'autres vers l'intérieur ; cette disposition particulière, dont le but est d'améliorer l'efficacité du nettoyage et d'éviter les blessures des gencives, n'est nullement adaptée pour faciliter le brossage des dents en présence de verrous redresseurs, ni pour permettre le brossage de ces verrous eux-mêmes.We also know, from patent FR-830 801, a toothbrush which has a brushing head provided with several rows of bristle tufts - or latches - some of which are inclined outwards and others inwards ; this particular arrangement, the aim of which is to improve the effectiveness of cleaning and to avoid injury to the gums, is in no way adapted to facilitate brushing of the teeth in the presence of straightening latches, or to allow the brushing of these latches themselves.
La présente invention vient maintenant améliorer la situation en proposant une brosse à dents orthodontique, caractérisée par une tête de brossage comportant d'une part deux groupes latéraux et longitudinaux de touffes de poils qui comprennent chacun des touffes inclinées vers l'extérieur de la tête de brossage en divergeant par rapport à un plan médian longitudinal de la tête, et des touffes convergeant vers ce plan médian longitudinal, d'autre part au moins une rangée centrale longitudinale de touffes de poils de longueur plus faible, parallèles au plan médian longitudinal.The present invention now improves the situation by proposing an orthodontic toothbrush, characterized by a brushing head comprising on the one hand two lateral and longitudinal groups of bristle tufts which each include tufts inclined towards the outside. of the brushing head diverging from a longitudinal median plane of the head, and tufts converging towards this longitudinal median plane, on the other hand at least one longitudinal central row of tufts of bristles of shorter length, parallel to the plane longitudinal median.
Une telle brosse à dents permet en particulier, sans imposer un mouvement de brossage spécifique et cela est important dans la mesure ou de jeunes enfants portent fréquemment des verrous redresseurs, d'atteindre et brosser correctement le collet des dents, la jonction bagues ou bases des verrous-dents et la zone de la papille inter- dentaire , qui constituent les zones les plus difficiles à nettoyer à l'aide de brosses classiques et donc les zones les plus sujettes aux caries.Such a toothbrush allows in particular, without imposing a specific brushing movement and this is important insofar as young children frequently wear straightening latches, to reach and brush correctly the collar of the teeth, the junction of rings or bases of the toothpicks and the area of the inter-dental papilla, which are the most difficult areas to clean using conventional brushes and therefore the areas most prone to cavities.
Selon une autre caractéristique importante de la présente invention, la différence de longueur entre les poils des groupes latéraux et les poils de la rangée centrale égale sensiblement l'épaisseur des verrous redresseurs, et de préférence est de l'ordre de 2mm.According to another important characteristic of the present invention, the difference in length between the bristles of the lateral groups and the bristles of the central row substantially equal the thickness of the straightening latches, and preferably is of the order of 2mm.
De préférence selon l'invention, les axes de toutes les touffes sont contenus dans des plans transversaux perpendiculaires audit plan médian longitudinal et à la surface moyenne de la tête portant les touffes.Preferably according to the invention, the axes of all the tufts are contained in transverse planes perpendicular to said longitudinal median plane and to the average surface of the head carrying the tufts.
Selon un mode de réalisation préférentiel de la présente invention, chaque groupe latéral de touffes comprend deux rangées longitudinales de touffes qui divergent et convergent respectivement par rapport au plan médian longitudinal de la tête de brossage.According to a preferred embodiment of the present invention, each lateral group of tufts comprises two longitudinal rows of tufts which diverge and converge respectively with respect to the longitudinal median plane of the brushing head.
Par ailleurs, selon la présente invention, l'extrémité du manche opposée à la tête de brossage est avantageusement adaptée pour supporter de façon amovible des accessoires pour l'hygiène dentaire, en particulier des accessoires tels que des brossettes interdentaires ou des portes fils de soies dentaires.Furthermore, according to the present invention, the end of the handle opposite to the brushing head is advantageously adapted to removably support accessories for dental hygiene, in particular accessories such as interdental brushes or bristle holders. dental.

Comme cela est illustré sur la figure 7, les rangées latérales de touffes convergentes 33, 37 permettent de nettoyer la jonction base des verrous-dents ou bords des bagues-dents. Entre les dents, ces poils des rangées 33 et 37 se glissent sous les arcs A et permettent de nettoyer les faces proximales des dents.As illustrated in FIG. 7, the lateral rows of converging
De même, les rangées latérales de touffes divergentes 32, 36 brossent le bord libre des dents et le collet, l'axe de ces touffes étant tel que leurs poils peuvent passer sous la gencive.Similarly, the lateral rows of
Les touffes 40 brossent les verrous V et les arcs A.The
Comme cela est illustré sur le bas des figures 1 et 2, ainsi que sur les figures 5, 6 et 8, l'extrémité 23 du manche opposée à la tête de brossage 30 est de préférence adaptée pour supporter de façon amovible des accessoires 60, 70 permettant de parfaire le nettoyage.As illustrated on the bottom of FIGS. 1 and 2, as well as on FIGS. 5, 6 and 8, the
Les accessoires 60, 70 seront fixés de façon amovible sur l'extrémité 23 du manche à l'aide de tous moyens classiques appropriés tels que des moyens à encliquetage ou à baïonnette.The
Selon le mode de réalisation représenté sur les figures, l'extrémité 23 du manche comprend une lumière traversante 50, formée d'un alésage cylindrique central 51 dans lequel débouchent deux rainures 52, 53 de section droite rectangulaire, diamètralement opposées.According to the embodiment shown in the figures, the
Par ailleurs, chacun des accessoires 60, 70 comprend une embase 61, 71 qui comporte une tige cylindrique 62, 72 complémentaire de l'alésage 51, et qui porte à son extrémité libre un barreau transversal 53, 73 complémentaire des rainures 52, 53.Furthermore, each of the
L'homme de l'art comprendra aisément que pour fixer les accessoires 60, 70 sur le manche de la brosse à dents 10, il faut aligner les barreaux 63, 73 sur les rainures 52, 53, engager ensuite les barreaux 63, 73 et les tiges 62, 72 dans les lumières 50, puis faire pivoter les embases 61, 71 d'un quart de tour, autour de l'axe 64, 74 des tiges lorsque les barreaux 63, 73 ont traversé les lumières.Those skilled in the art will easily understand that to fix the
Ce pivotement peut être limité par des butées prévues en relief sur le manche 20.This pivoting can be limited by stops provided in relief on the
La longueur des tiges 62, 72 est de préférence sensiblement identique, voire inférieure à l'épaisseur m du manche 20,pour obtenir une immobilisation des accessoires 60, 70 sur ce dernier après le pivotement précité.The length of the
Pour faciliter ce pivotement tout en garantissant une immobilisation ferme des accessoires 60, 70, on peut aussi envisager de réaliser des bossages élastiques sur le manche 21 destinés à pénétrer dans des incurvations réalisées sur les barreaux 63, 73 ou les embases 61, 71, ou inversement de réaliser des bossages élastiques sur les barreaux 63, 73 ou les embases 61, 71 destinés à pénétrer dans des incurvations réalisées sur les manches 21.To facilitate this pivoting while guaranteeing a firm immobilization of the
On a représenté sur la figure 5, une brossette inter- dentaire 60 comprenant une brosse 65 portée par l'embase 61 précitée.There is shown in Figure 5, an
Cette brossette 65 présentent de préférence une forme générale tronconique effilée vers son extrémité libre. Néanmoins, une brossette de forme générale cylindrique peut être utilisée.This
A titre d'exemple non limitatif, la brossette 65 peut être composée, de façon classique en soi, de deux fils métalliques torsadés centraux qui coincent les brins de la brosse. La longueur active de la brossette est par exemple de 12 mm.By way of nonlimiting example, the
Cette brossette 65 est, en particulier, adaptée pour passer sous les arcs A, entre les dents, comme illustré sur la figure 8 pour éliminer la plaque bactérienne qui se fixe à ces endroits, par mouvement vertical, schématiquement illustré M.This
Cette brossette 65 permet également d'assurer le brossage des faces proximales des dents, en particulier lorsque les dents sont espacées, ou après des extractions.This
On a représenté sur la figure 7 un porte fil de soie dentaire 70.FIG. 7 shows a dental floss holder 70.
Celui-ci comprend une embase 71 en forme générale de U.This includes a base 71 in a general U shape.
Plus précisément, l'âme 75 de l'embase porte deux ailes 76, 77 parallèles fendues à leurs extrémités libres pour recevoir sous tension un fil de soie 78.More specifically, the
Ce fil de soie 78 pourra être immobilisé sur l'embase 71 à l'aide de tous moyens classiques appropriés, par exemple par simple enroulement sur les extrémités des ailes 76, 77 qui, grâce à leur élasticité, maintiennent le fil 78 sous tension.This
Ce fil 78 est destiné à être passé entre les dents dans les zones sans arc A.This
Bien entendu, la présente invention n'est pas limitée au mode de réalisation particulier qui vient d'être décrit mais s'étend à toute variante conforme à son esprit.Of course, the present invention is not limited to the particular embodiment which has just been described but extends to any variant in accordance with its spirit.
