Description

Appareil orthodontique pour enfantsOrthodontic appliance for children
La présente invention concerne un appareil orthodontique pour enfants comportant une téterelle ainsi que deux écrans séparés par une liaison de manière à s'étendre de part et d'autre des lèvres du porteur de l'appareil. Un tel dispositif est décrit dans la demande de brevet FR-A-2.792.186 du demandeur.The present invention relates to an orthodontic appliance for children comprising a breast shield and two screens separated by a link so as to extend on either side of the lips of the wearer of the appliance. Such a device is described in the patent application FR-A-2,792,186 of the applicant.
Un tel appareil orthodontique est spécialement destiné aux enfants d'une tranche d'âge déterminé et permet d'assurer un positionnement constant des lèvres. Ainsi, les lèvres de l'enfant sont guidées dans le couloir formé entre les deux écrans, le premier écran venant en position interne et le second écran en position externe. Un tel appareil favorise la mise en place de la déglutition secondaire (dite adulte) en évitant le passage de la langue vers la lèvre inférieure et les joues lors de la déglutition.Such an orthodontic appliance is specially intended for children of a determined age group and makes it possible to ensure constant positioning of the lips. Thus, the child's lips are guided in the corridor formed between the two screens, the first screen coming in the internal position and the second screen in the external position. Such a device promotes the establishment of secondary swallowing (so-called adult) by avoiding the passage of the tongue towards the lower lip and the cheeks during swallowing.
L'appareil comporte une partie supérieure et une partie inférieure qui s'étendent respectivement au-dessus et au-dessous d'un plan longitudinal de l'écran interne, en particulier un plan longitudinal médian de ce dernier. La partie supérieure correspond à la partie de l'appareil située du côté de l'arcade dentaire supérieure et la partie inférieure à la partie de l'appareil situé du côté de l'arcade dentaire inférieure.The apparatus comprises an upper part and a lower part which extend respectively above and below a longitudinal plane of the internal screen, in particular a median longitudinal plane of the latter. The upper part corresponds to the part of the appliance located on the side of the upper dental arch and the lower part corresponds to the part of the appliance located on the side of the lower dental arch.
Avec un tel appareil, on évite une compression des arcades dentaires et une projection des lèvres vers l'avant lorsqu'elles se contractent bouche fermée ou par contraction entre autre de la houppe du menton et on favorise la ventilation nasale ainsi que la mise en place de la déglutition secondaire dite adulte. Une telle sucette permet également de favoriser l'action de la téterelle. Dans les cas de décalage entre les deux arcades dentaires, on a pu remarquer que les incisives inférieures peuvent ne pas se placer correctement par rapport à la téterelle, ce qui peut nuire à la tenue dans le temps de l'appareil.With such a device, compression of the dental arches and projection of the lips forward when they contract closed mouth or by contraction of, inter alia, the chin tassel are avoided, and nasal ventilation is encouraged as well as the positioning so-called adult secondary swallowing. Such a pacifier also promotes the action of the breast shield. In the case of a mismatch between the two dental arches, it has been noted that the lower incisors may not be positioned correctly relative to the nipple, which can affect the durability of the device.
De plus, on a également remarqué qu'au niveau de la partie supérieure de l'appareil, la pression exercée par la langue lors de la déglutition n'est pas optimale.In addition, it has also been noted that at the level of the upper part of the apparatus, the pressure exerted by the tongue during swallowing is not optimal.
Dans le brevet US-A-3 825 014, on propose une tétine dont la téterelle présente six nervures allongées en saillie radiale vers l'intérieur de la téterelle depuis la surface interne de ceile-ci. Ces nervures sont réparties de manière uniforme et symétrique dans la téterelle ce qui donne une résistance égale quelle que soit la façon dont l'on presse la téterelle, ce qui permet d'éviter un écrasement de la téterelle. La présence de ces nervures ne permet cependant pas de compenser le décalage entre les deux arcades dentaires, en effet, la répartition uniforme des nervures ne laisse pas la souplesse verticale s'exercer pour la stimulation du palais et le développement ascensionnel de la langue.In patent US-A-3 825 014, a nipple is proposed, the nipple of which has six elongated ribs projecting radially towards the inside of the nipple from the internal surface of this nipple. These ribs are distributed uniformly and symmetrically in the nipple, which gives equal resistance regardless of how the nipple is pressed, which prevents crushing of the nipple. The presence of these ribs does not, however, compensate for the offset between the two dental arches, in fact, the uniform distribution of the ribs does not allow the vertical flexibility to be exerted for the stimulation of the palate and the upward development of the tongue.
Le brevet US-A-5 275 619 propose une tétine destinée aux enfants prématurés et à ceux présentant un petit poids de naissance. La téterelle est prévue longue et fine et comporte des renforts avec un épaississement de sa paroi pour durcir ou rendre moins souple la téterelle. Ces configurations particulières proposées dans ce brevet permettent de concevoir une téterelle simulant le pouce ou le sein. Les tétines proposées dans ce document sont destinées à des enfants venant de naître pour lesquels le problème du déplacement mandibulaire et dentaire inférieur vers l'avant ou encore la notion de butée mandibulaire ne se posent pas.US-A-5,275,619 proposes a pacifier intended for premature children and those with a low birth weight. The nipple is provided long and thin and has reinforcements with a thickening of its wall to harden or make the nipple less flexible. These particular configurations proposed in this patent make it possible to design a nipple simulating the thumb or the breast. The teats proposed in this document are intended for children who have just been born for whom the problem of mandibular and lower dental displacement towards the front or the notion of mandibular stop does not arise.
Par ailleurs, la présence de nervures ou renfort sur l'intérieur des téterelles engendrent des difficultés lors du nettoyage de ces tétines,' les renforts ou nervures favorisant la rétention de la saleté dans la téterelle. On connaît également du brevet AT-A-396 869, une téterelle pleine dans laquelle est mise en place une structure de renfort style colonne grecque chargée de soutenir l'ensemble. Cette téterelle ne permet pas de conserver la souplesse pour les pressions verticalesMoreover, the presence of ribs or reinforcement on the interior of nipple shields create difficulties when cleaning these teats, 'reinforcements or ribs promoting retention of the dirt in the breastshield. Also known from patent AT-A-396,869, a full nipple in which is placed a Greek column-style reinforcing structure responsible for supporting the assembly. This nipple does not keep flexibility for vertical pressures
Aussi, la présente invention vise à proposer un appareil orthodontique dans lequel on favorise un placement efficace des incisives inférieures tout en optimisant la pression exercée lors de la déglutition.Also, the present invention aims to provide an orthodontic appliance in which an efficient placement of the lower incisors is favored while optimizing the pressure exerted during swallowing.
A cet effet, l'invention a pour objet un appareil othodontique pour enfants, comportant une téterelle ainsi qu'un écran interne et un écran externe séparés par une liaison de manière à s'étendre de part et d'autre des lèvres du porteur, l'appareil présentant une partie supérieure et une partie inférieure qui s'étendent respectivement au-dessus et au-dessous d'un plan longitudinal de l'écran interne, en particulier un plan longitudinal médian de ce dernier, caractérisé en ce que la téterelle présente sur sa partie inférieure et/ou sur sa partie supérieure, un renfort permettant d'accroître la rigidité de la téterelle.To this end, the subject of the invention is an orthodontic appliance for children, comprising a breast shield as well as an internal screen and an external screen separated by a link so as to extend on either side of the wearer's lips, the apparatus having an upper part and a lower part which extend respectively above and below a longitudinal plane of the internal screen, in particular a median longitudinal plane of the latter, characterized in that the nipple has on its lower part and / or on its upper part, a reinforcement making it possible to increase the rigidity of the nipple shield.
De préférence, la téterelle étant un corps creux, le renfort est obtenu par un épaississement des parois de la téterelle dans la partie supérieure et/ou inférieure de ladite téterelle.Preferably, the nipple being a hollow body, the reinforcement is obtained by thickening the walls of the nipple in the upper and / or lower part of said nipple.
De manière avantageuse, l'accroissement de la rigidité dans la partie inférieure de la téterelle permet de réaliser un plan de glissement qui optimise de manière très efficace la propulsion des incisives inférieures vers l'écran interne et résiste à la pression desdites incisives inférieures. Ce plan de glissement assure ainsi un positionnement correct des incisives inférieures qui se retrouvent calées entre la téterelle et l'écran interne malgré un décalage éventuel entre les deux arcades dentaires, l'écran servant de butée et de guide pour les incisives.Advantageously, the increase in rigidity in the lower part of the nipple makes it possible to produce a sliding plane which optimizes very effectively the propulsion of the lower incisors towards the internal screen and resists the pressure of said lower incisors. This sliding plane thus ensures correct positioning of the lower incisors which are wedged between the nipple and the internal screen despite a possible offset between the two dental arches, the screen serving as a stop and guide for the incisors.
En outre, la rigidité renforcée de la partie inférieure de la téterelle permet également une meilleure tenue dans le temps de l'appareil dentaire et, de ce fait, une durée de vie plus longue de ce dernier.In addition, the reinforced rigidity of the lower part of the nipple also allows a better hold over time of the dental appliance and, therefore fact, a longer lifespan of the latter.
L'augmentation de la rigidité dans la partie supérieure de la téterelle crée une augmentation de la pression exercée sur le palais lors de la déglutition. Cette pression plus grande assure une meilleure stimulation qui favorise la croissance du palais.The increased stiffness in the upper part of the nipple creates an increase in the pressure exerted on the palate during swallowing. This greater pressure provides better stimulation which promotes growth of the palate.
Cette croissance se réalise en particulier par la stimulation du paquet vasculo- nerveux issu du canal naso-palatin et des sutures premaxillo-maxiliaires et intermaxillaires ainsi que de la circulation sanguine.This growth is achieved in particular by stimulating the vasculo-nervous package from the nasopalatine canal and premaxillo-maxillary and intermaxillary sutures as well as the blood circulation.
On obtient ainsi un meilleur développement antéro-latéral de la mâchoire supérieure et en particulier du prémaxillaire. On évite ainsi de manière avantageuse, les hypodéveloppements du prémaxillaire qui sont à l'origine des encombrements dentaires.This gives better antero-lateral development of the upper jaw and in particular of the premaxilla. This avoids advantageously, the hypodevelopments of the premaxilla which are the cause of dental congestion.
En outre, les épaississements en position inférieure et/ou supérieure laissent la souplesse verticale s'exercer pour la stimulation du palais et le développement ascensionnel de la langue tout en conservant la dureté nécessaire au plan de glissement et à l'écrasement sur le palais.In addition, the thickenings in the lower and / or upper position allow the vertical flexibility to be exerted for the stimulation of the palate and the upward development of the tongue while retaining the hardness necessary for the plane of sliding and for crushing on the palate.
De plus, pour le nourrisson dépourvu de dents, la tétée s'effectue par succion- aspiration et met en jeu un déplacement mandibulaire dans un mouvement vers le haut et l'avant puis vers le bas et l'arrière. Ces mouvements, s'ils persistent au-delà de l'âge de 3 ans environ, sont la cause des malpositions mandibulaires (promandibulaire ou rétromandibulaire). Le renfort prévu sur l'appareil orthodontique selon l'invention permet un glissement des dents inférieures vers l'avant et grâce à la présence de l'écran adjoint a pour but de faire disparaître la tétée du nourrisson, car étant en contact avec l'écran, les lèvres ne peuvent plus influencer les positions mandibulaires. La synergie écran-plan de glissement renforcé lorsque le sujet est denté et non plus un nourrisson optimise le travail de l'appareil orthodontique. De manière avantageuse, on peut prévoir, en fonction de la dentition du porteur de l'appareil, de lui proposer un appareil orthodontique pourvu d'un renfort uniquement dans la partie supérieure, ou un appareil pourvu d'un renfort uniquement dans la partie inférieure ou encore un appareil pourvu des deux renforts.In addition, for infants without teeth, suckling is done by suction-suction and involves mandibular displacement in an upward and forward movement, then downward and rearward movement. These movements, if they persist beyond the age of about 3 years, are the cause of mandibular malpositions (promandibular or retromandibular). The reinforcement provided on the orthodontic appliance according to the invention allows the lower teeth to slide forward and, thanks to the presence of the adjoining screen, is intended to make the feeding of the infant disappear, since it is in contact with the screen, the lips can no longer influence the mandibular positions. The synergy between the screen and the enhanced sliding plane when the subject is toothed and no longer an infant optimizes the work of the orthodontic appliance. Advantageously, provision may be made, depending on the dentition of the wearer of the appliance, to offer him an orthodontic appliance provided with a reinforcement only in the upper part, or an appliance provided with a reinforcement only in the lower part. or a device provided with two reinforcements.
De plus, la téterelle et l'écran interne sont réalisés par moulage au moyen d'un noyau et la présence du ou des épaississements sur la téterelle facilite le démoulage de la pièce. L'invention offre de surcroît une fabrication plus aisée qu'avant.In addition, the nipple and the internal screen are produced by molding by means of a core and the presence of the thickening (s) on the nipple facilitates demolding of the part. The invention also offers easier manufacturing than before.
En effet, L'invention sera décrite plus en détail en référence au dessin en annexe dans lequel :Indeed, the invention will be described in more detail with reference to the accompanying drawing in which:
la figure 1 représente une vue en coupe longitudinale d'un appareil selon un exemple de réalisation de l'invention ; etFigure 1 shows a longitudinal sectional view of an apparatus according to an exemplary embodiment of the invention; and
la figure 2 représente une vue en coupe longitudinale d'un appareil selon un autre exemple de réalisation.FIG. 2 represents a view in longitudinal section of an apparatus according to another exemplary embodiment.
L'appareil orthodontique décrit dans la figure 1 comporte une téterelle 1 asymétrique appelée téterelle physiologique ainsi que deux écrans. Seule une moitié 2 de l'écran interne est visible dans la figure 1 , représentée selon une ligne en pointillés. Généralement, au moins l'un des bords supérieur ou inférieur de l'écran interne présente une concavité de préférence au voisinage de la liaison entre lesdits écrans.The orthodontic appliance described in FIG. 1 comprises an asymmetrical teat 1 called a physiological teat as well as two screens. Only half 2 of the internal screen is visible in FIG. 1, represented along a dotted line. Generally, at least one of the upper or lower edges of the internal screen preferably has a concavity in the vicinity of the connection between said screens.
La partie supérieure de la téterelle 2 présente un épaississement 3 constituant le renfort pour accroître la rigidité. Comme cela est visible cet épaississement augmente la pression exercée sur le palais lors de la déglutition. La partie inférieure de la téterelle comporte un épaississement 4 constituant le renfort pour accroître la rigidité.The upper part of the nipple 2 has a thickening 3 constituting the reinforcement to increase the rigidity. As can be seen, this thickening increases the pressure exerted on the palate during swallowing. The lower part of the nipple has a thickening 4 constituting the reinforcement to increase rigidity.
La téterelle 1 étant asymétrique, la partie inférieure de celle-ci présente un premier plan incliné 5 descendant partant de l'extrémité libre de la téterelle 1 vers l'écran interne prolongé d'un second plan incliné 6 ascendant s'étendant jusque dans la zone de liaison de la téterelle 1 à l'écran interne, l'épaississement 4 étant réalisé sensiblement au sommet entre les deux plans 6, 7 et définissant avec le second plan incliné 6 un plan de glissement des dents.The nipple 1 being asymmetrical, the lower part thereof has a first inclined plane 5 descending from the free end of the nipple 1 towards the internal screen extended by a second inclined plane 6 ascending extending into the area of connection of the nipple 1 to the internal screen, the thickening 4 being carried out substantially at the top between the two planes 6, 7 and defining with the second inclined plane 6 a plane of sliding of the teeth.
Cet épaississement 4 définit alors avec le second plan incliné 6, un plan de glissement pour les incisives inférieures encore plus prononcé qui permet d'optimiser la propulsion des incisives inférieures vers l'écran interne 2 et de caler celles-ci entre l'épaississement 4 et l'écran interne 2. Ainsi, on favorise le positionnement des dents au voisinage de l'écran interne notamment en cas de décalage entre les deux arcades.This thickening 4 then defines with the second inclined plane 6, a sliding plane for the lower incisors even more pronounced which makes it possible to optimize the propulsion of the lower incisors towards the internal screen 2 and to wedge them between the thickening 4 and the internal screen 2. Thus, the positioning of the teeth in the vicinity of the internal screen is favored, in particular in the event of a shift between the two arches.
La partie supérieure de la téterelle 1 asymétrique présente une forme de demi- sphère, l'épaississement étant ménagé de préférence dans la calotte sphérique correspondant à la partie destinée à venir en contact avec le palais.The upper part of the asymmetrical nipple 1 has the shape of a hemisphere, the thickening preferably being provided in the spherical cap corresponding to the part intended to come into contact with the palate.
Dans la figure 2 est représenté un appareil orthodontique pourvu d'une téterelle 10 symétrique, par exemple en forme dite de « cerise » ou encore de forme aplatie dont une seule moitié de l'écran interne 20 est représentée. L'écran externe est représenté en pointillés sous la référence 70.In FIG. 2 is shown an orthodontic appliance provided with a symmetrical nipple 10, for example in the so-called “cherry” shape or in a flattened shape of which only one half of the internal screen 20 is shown. The external screen is shown in dotted lines under the reference 70.
La partie supérieure présente un épaississement 30 et la partie inférieure est pourvue d'un épaississement 40. Ces deux épaississements constituent les renforts pour augmenter la rigidité. Dans le cas de la téterelle sphérique, les épaississements sont ménagés dans les deux calottes sphériques opposées. De préférence, la téterelle étant symétrique, les épaississements 30, 40 de la partie supérieure et de la partie inférieure de ladite téterelle sont réalisés de manière symétrique sur celle-ci.The upper part has a thickening 30 and the lower part is provided with a thickening 40. These two thickenings constitute the reinforcements to increase the rigidity. In the case of the spherical shield, the thickenings are provided in the two opposite spherical caps. Preferably, the nipple being symmetrical, the thickenings 30, 40 of the upper part and of the lower part of said nipple are made symmetrically thereon.
Comme cela est visible aux figures 1 et 2, la téterelle 1 , 10 est formée sous forme d'une seule pièce avec l'écran interne 2, 20. Cette pièce est ensuite rapportée sur l'écran externe (non représenté à la figure 1 ), la fixation s'opérant par tous moyens de fixation appropriés tels qu'encliquetage, collage etc. de l'extrémité libre 50 de ladite pièce sur l'écran externe. As can be seen in Figures 1 and 2, the nipple 1, 10 is formed in one piece with the internal screen 2, 20. This part is then attached to the external screen (not shown in Figure 1 ), the fixing being effected by any suitable fixing means such as snap-fastening, gluing, etc. of the free end 50 of said part on the external screen.
