  • adaptive material means that the material becomes malleable during the process of adjusting the PIB.
  • support is meant that the pallet cooperates with the skeleton to allow both a sufficient thickness of material at the incisivo-canine block and a ventilatory space sufficient for good ventilation of the user.

Description

La présente invention concerne, d'une manière générale, le domaine des protections intra-buccales (PIB) adaptables destinées à protéger les personnes contre les conséquences d'un impact crânio-facial.The present invention generally relates to the field of adaptive intraoral protections (PIBs) for protecting individuals against the consequences of craniofacial impact.

Par « adaptable » on entend les PIB aptes à être mises en forme dans la bouche.By "adaptable" we mean the PIBs able to be shaped in the mouth.

La présente invention concerne notamment, mais non exclusivement, les PIB adaptables par thermo-adaptation à l'eau chaude.The present invention relates in particular, but not exclusively, to adaptable PIBs by thermo-adaptation to hot water.

La présente invention sert, plus particulièrement, mais non exclusivement, lors de la pratique des sports à risque de traumatismes buccodentaires, maxillo-faciaux, cérébraux et cervicaux. Elle peut viser d'autres domaines comme par exemple celui de la santé pour la prévention des traumatismes buccodentaires qui peuvent se produire lors d'une intubation endotrachéale.The present invention serves, more particularly, but not exclusively, when practicing sports at risk of oral, maxillofacial, cerebral and cervical trauma. It can target other areas such as health for the prevention of oral trauma that can occur during endotracheal intubation.

Le sport est l'une des principales causes de traumatismes buccodentaires. L'Association Dentaire Américaine et l'Académie d'Odontologie du Sport ont établi une liste de sports et d'activités de loisirs à risque pour lesquels ils recommandent l'utilisation d'une PIB bien adaptée, comme par exemple, les arts martiaux, le baseball, le basketball, la boxe, le cyclisme, le football, la gymnastique, l'haltérophilie, le handball, le hockey, la lutte, le parachutisme, le rugby, le skateboard, le ski, les sports équestres, le squash, le surf, le volleyball ou encore le water polo.Sport is one of the main causes of oral trauma. The American Dental Association and the Academy of Sport Odontology have compiled a list of sports and recreational activities at risk for which they recommend the use of a well-adapted GDP, such as, for example, martial arts, baseball, basketball, boxing, cycling, football, gymnastics, weightlifting, handball, hockey, wrestling, parachuting, rugby, skateboarding, skiing, equestrian sports, squash, surfing, volleyball or even water polo.

Les PIB ont vu le jour dans les années 1890 en Angleterre et avaient, à l'origine, pour objectif de protéger les pratiquants de boxe anglaise de coupures aux lèvres occasionnées par leur activité sportive.GDP was born in the 1890s in England and was originally intended to protect English boxing practitioners from cuts to the lips caused by their sporting activity.

De son premier rôle de protège-muqueuse, la PIB a évolué pour devenir tout d'abord une protection des structures buccodentaires et maxillaires, puis son rôle s'est étendu à la prévention des commotions cérébrales et des traumatismes cervicaux durant la pratique de sports à risques.From its first role as a mucosal protector, GDP has evolved to become first of all a protection of the oral and maxillary structures, then his role extended to the prevention of concussions and cervical injuries during the practice of risky sports.

Une PIB a donc, entre autres, pour objectifs :

  • de réduire le risque de lésion des tissus mous (la langue, les lèvres et les joues) ;
  • de réduire le risque de lésion des dents antérieures maxillaires ;
  • de réduire le risque de lésion buccodentaire par choc violent inter-arcades ;
  • de réduire le risque de commotion cérébrale ;
  • de réduire le risque d'atteinte cervicale.
One of the goals of a GDP is to:
  • reduce the risk of soft tissue injury (tongue, lips and cheeks);
  • reduce the risk of injury to maxillary anterior teeth;
  • reduce the risk of oral injury by violent inter-arcade shock;
  • reduce the risk of concussion;
  • to reduce the risk of cervical involvement.

Une PIB a de plus, entre autres, pour propriétés :

  • d'occuper les espaces édentés ;
  • de permettre un engrènement des arcades dentaires mandibulaire et maxillaire ;
  • d'être confortable ;
  • de ne pas présenter de saillie, ni de rugosité ;
  • d'être rétentive ;
  • d'absorber et dissiper l'énergie d'impact ;
  • de permettre la phonation ;
  • de permettre la ventilation buccale mâchoires serrées.
GDP has moreover, among others, for properties:
  • to occupy edentulous spaces;
  • to allow a meshing of the mandibular and maxillary dental arches;
  • to be comfortable;
  • not to show protrusion or roughness;
  • to be retentive;
  • absorb and dissipate impact energy;
  • to allow phonation;
  • to allow oral ventilation tight jaws.

On entend par « rétentive » la capacité de la PIB à rester en place quand l'utilisateur ouvre la bouche.Retention is the ability of GDP to stay in place when the user opens the mouth.

On entend par « engrènement » la pénétration des dents antagonistes dans le bourrelet occlusal de la gouttière pour obtenir le calage des arcades mandibulaire et maxillaire.The term "meshing" means the penetration of the opposing teeth into the occlusal rim of the trough to obtain the wedging of the mandibular and maxillary arches.

On entend par « phonation » la capacité de l'utilisateur à pouvoir s'exprimer oralement."Phonation" means the ability of the user to express himself orally.

Trois types de PIB sont actuellement couramment proposés :

  • Type I : modèle standard, uni ou bi-maxillaires. Il s'agit d'une PIB prête à l'emploi. Une telle PIB présente cependant comme inconvénients :
  • de ne pas permettre l'engrènement des arcades dentaires mandibulaire et maxillaire ;
  • de ne pas être rétentive : elle ne tient en place que lorsque le sportif est mâchoires serrées ;
  • de gêner la ventilation du sportif et, de plus, il y a un risque que la protection s'échappe durant l'effort et qu'elle se coince dans les voies aériennes du sportif.
  • Type II : modèle adaptable, uni ou bi-maxillaires, Il s'agit d'une PIB apte à être mise en forme dans la bouche de l'utilisateur. Une telle PIB peut cependant présenter comme inconvénients :
  • de perdre jusqu'à 99% d'épaisseur lors de l'adaptation en bouche, ce qui limite l'absorption et la dissipation de l'énergie d'impact ;
  • de limiter la ventilation buccale mâchoires serrées.
  • Type III : modèle sur mesure. Il s'agit d'une PIB réalisée après prise d'empreintes des arcades dentaires mandibulaire et maxillaire de l'utilisateur. Le mode de préparation (sur mesure) doit permettre la confection d'une PIB de haute qualité conforme aux critères essentiels d'objectifs et de propriétés reconnus pour ce dispositif de prévention. Cependant, en fonction des
Three types of GDP are currently proposed:
  • Type I: standard model, uni or bimaxillary. It is a ready-to-use GDP. Such a GDP, however, has the following disadvantages:
  • not to allow the meshing of the mandibular and maxillary dental arches;
  • not to be retentive: it only holds in place when the athlete is tight jaws;
  • to interfere with the athlete's ventilation and, moreover, there is a risk that the protection escapes during the effort and gets stuck in the athlete's airway.
  • Type II: adaptable model, uni or bimaxillary, This is a PIB able to be formatted in the mouth of the user. Such a GDP may, however, have the following disadvantages:
  • to lose up to 99% thickness during adaptation in the mouth, which limits the absorption and dissipation of impact energy;
  • to limit mouth ventilation tight jaws.
  • Type III: customized model. This is a GDP performed after taking impressions of the mandibular and maxillary dental arches of the user. The (tailor-made) method of preparation must allow the production of a high-quality GDP in accordance with the essential criteria of objectives and properties recognized for this prevention device. However, depending on

opérateurs, certaines de ces PIB peuvent présenter une qualité inférieure à des modèles de type Il en terme d'épaisseur de matériau et d'aptitude de ventilation mâchoires serrées.operators, some of these PIBs may have lower quality than Type II models in terms of material thickness and tight jaw ventilation ability.

Les PIB de type II, c'est à dire apte à mettre en forme dans la bouche, par exemple après ramollissement dans de l'eau chaude, représentent près de 90% des PIB actuellement portées par les sportifs.GDP type II, ie able to shape in the mouth, for example after softening in hot water, represent nearly 90% of GDP currently worn by athletes.

La conservation des épaisseurs de matériau de la PIB est nécessaire à une absorption et une dissipation correctes des énergies liées aux impacts.The preservation of the material thicknesses of the PIB is necessary for a correct absorption and dissipation of the energy related to the impacts.

De plus, des études ventilatoires ont montré que des PIB, tous types confondus, amenaient plus de résistance à l'air et réduisaient significativement l'aptitude de l'athlète à ventiler mâchoires serrées.In addition, ventilatory studies have shown that all types of PIBs lead to greater air resistance and significantly reduce the athlete's ability to ventilate tight jaws.

Cette réduction de la ventilation mâchoires serrées se traduit par une hypoxie, une hypercapnie et le résultat logique est une diminution de la performance.This reduction in tight jaw ventilation results in hypoxia, hypercapnia and the logical result is a decrease in performance.

Cette réduction de la ventilation mâchoires serrées se traduit par un mouvement d'ouverture buccale indispensable pour réduire l'hypoxie et l'hypercapnie provoquée par l'effort mâchoires serrées. Mais, ce mouvement provoque deux conséquences majeures :

  • un risque majoré de traumatismes après impact sur une mandibule désolidarisée du massif facial, dite « mandibule projectile », tels que des lésions dentaires par choc inter-arcades, un K.O. à prédominance posturale ou une fracture mandibulaire consécutifs à la percussion de la zone postérieure de l'éminence temporale par le processus condylaire.
  • un risque majoré de commotion cérébrale et de traumatisme du rachis cervical par un ébranlement du haubanage musculaire de l'ensemble crânio-facial et cervical et donc une perturbation dans le maintien de la tête et du cou.
This reduction in tight jaw ventilation results in an oral opening movement essential to reduce hypoxia and hypercapnia caused by tight jaw strain. But, this movement causes two major consequences:
  • increased risk of trauma after impact on a dislocated mandible of the facial mass, called "mandible projectile", such as dental lesions by inter-arcade shock, a predominantly postural KO or a mandibular fracture consecutive to the percussion of the posterior zone of the temporal eminence by the condylar process.
  • an increased risk of concussion and cervical spine trauma by shaking the muscular guying of the craniofacial and cervical complex and thus a disruption in the maintenance of the head and neck.

L'objectif est donc de proposer une PIB adaptable permettant de garantir la ventilation buccale mâchoires serrées de l'utilisateur et la conservation des épaisseurs de la PIB après la procédure de mise en forme intra-orale.The aim is therefore to propose an adaptable PIB to guarantee the user's tight oral jaw ventilation and the preservation of the thicknesses of the PIB after the intra-oral shaping procedure.

Parmi les nombreux brevets portant sur des PIB, on connait la demande de brevet internationale WO94/27691 au nom de E-Z GARD INDUSTRIES, qui a été publiée le 8 Décembre 1994, sous priorité d'une demande américaine US08/066,468 déposée en Mai 1993. Cette demande divulgue une protection en matériau composite, comprenant une gouttière maxillaire en un matériau thermo-adaptable et un squelette en un matériau non-thermo-adaptable destiné à absorber et dissiper les forces d'impact. La structure de cette PIB de type Il permet que le contact postérieur (i.e. au fond de la mâchoire) sur le matériau non-thermo-adaptable conserve un espace libre antérieur (i.e. au devant de la bouche, au niveau des incisives) pour ventiler et parler. Cependant, l'espace libre antérieur obtenu après la mise en forme de la PIB peut être insuffisant pour permettre une ventilation satisfaisante lorsque l'utilisateur serre les mâchoires. Par ailleurs, la présence du seul matériau non thermo-adaptable en regard des secteurs latéraux rend impossible l'empreinte de l'arcade dentaire mandibulaire lors de la procédure de mise en forme et donc ne permet pas l'engrènement entre les arcades dentaires mandibulaire et maxillaire.Among the many patents on GDP, we know the international patent application WO94 / 27691 in the name of EZ GARD INDUSTRIES, which was published on December 8, 1994, under priority of a US application US08 / 066.468 filed May 1993. This application discloses a composite material protection, comprising a maxillary gutter of a thermo-adaptable material and a skeleton of a non-thermo-adaptable material for absorbing and dissipating the impact forces. The structure of this GDP type II allows that the posterior contact (ie at the bottom of the jaw) on the non-thermo-adaptable material retains an anterior free space (ie in front of the mouth, at the level of the incisors) to ventilate and speak. However, the free space obtained after the shaping of the PIB may be insufficient to allow satisfactory ventilation when the user squeezes the jaws. Moreover, the presence of the only non-thermo-adaptable material facing the lateral sectors makes it impossible to imprint the mandibular dental arch during the shaping procedure and therefore does not allow meshing between the mandibular dental arches and maxillary.

Or, le sportif a besoin d'une part d'une ventilation suffisante en effectuant son effort mâchoires serrées, d'autre part que sa mandibule soit bien engrenée et solidarisée avec l'arcade dentaire maxillaire pour éviter le phénomène de « mandibule projectile ».However, the athlete needs on the one hand a sufficient ventilation by performing his jaws tight effort, on the other hand that his mandible is well meshed and secured to the maxillary dental arch to avoid the phenomenon of "mandible projectile".

On connait aussi la demande de brevet internationale WO98/34574 déposée en Février 1997 au nom de WIPSS PRODUCTS INC sous priorité d'une demande américaine US 5,636,379 déposée en Août 1995 qui divulgue également une protection en matériau composite. Un des inconvénients de ce produit est que la faible épaisseur de matériau thermo-adaptable autour du squelette en matériau non thermo-adaptable ne permet pas un engrènement suffisant entre les arcades dentaires mandibulaire et maxillaire lors de la procédure de mise en forme et donc ni un calage suffisant de la mandibule, ni une rétention suffisante de la PIB.We also know the international patent application WO98 / 34574 filed in February 1997 on behalf of WIPSS PRODUCTS INC under priority of US application US 5,636,379 filed in August 1995 which also discloses a composite material protection. One of the disadvantages of this product is that the small thickness of thermo-adaptable material around the skeleton of non-thermo-adaptable material does not allow sufficient meshing between the mandibular and maxillary dental arches during the formatting procedure and therefore neither a sufficient wedging of the mandible nor a sufficient retention of the GDP.

L'invention vise à remédier à ces inconvénients en proposant une PIB qui, après la procédure de mise en forme, permet une ventilation mâchoires serrées efficace quelle que soit la typologie dento-maxillo-faciale du sportif, tout en conservant des épaisseurs minimales de matériau pour une participation optimale de la PIB à la prévention des traumatismes buccodentaires, maxillo-faciaux, cérébraux et cervicaux.The invention aims to remedy these drawbacks by proposing a PIB which, after the shaping procedure, allows tight jaw ventilation to be effective regardless of the dento-maxillo-facial typology of the sportsman, while maintaining minimum thicknesses of material. for optimal GDP participation in the prevention of oral, maxillofacial, cerebral and cervical injuries.

A cet effet, est donc proposé, suivant un premier aspect de l'invention, une protection Intra-Buccale (PIB), apte à être mise en forme dans la bouche, et comprenant :

  • une structure adaptable, constituée d'un matériau adaptable, présentant une gouttière supérieure destinée à recevoir l'arcade dentaire maxillaire, et une gouttière inférieure destinée à recevoir l'arcade dentaire mandibulaire,
  • un squelette, au moins partiellement recouvert par la structure adaptable, constitué d'un matériau non adaptable,
  • la structure adaptable et le squelette étant agencés pour former
  • un bloc de protection incisivo-canin au moins au niveau des canines et des incisives supérieures,
  • et un bourrelet occlusal au niveau de chaque secteur dentaire latéral, i.e. au niveau des prémolaires et molaires supérieures et inférieures de chaque coté,
et qui comporte en outre une palette amovible, constituée d'un matériau non adaptable, comprenant une première zone destinée à venir en appui sur le squelette, de préférence au niveau du bloc incisivo-canin, et pas nécessairement en contact direct, ladite zone de la palette étant dimensionnée de sorte que, lors de la phase d'adaptation de la PIB, la présence conjointe de ladite palette et dudit squelette permet de garantir à la fois un espace ventilatoire et une présence de matière suffisants au niveau du bloc incisivo-canin.For this purpose, it is therefore proposed, according to a first aspect of the invention, intra-oral protection (PIB), able to be shaped in the mouth, and comprising:
  • an adaptable structure, consisting of an adaptable material, having an upper gutter for receiving the maxillary dental arch, and a lower gutter for receiving the mandibular dental arch,
  • a skeleton, at least partially covered by the adaptable structure, made of a non-adaptable material,
  • the adaptable structure and the skeleton being arranged to form
  • an incisivo-canine protection block at least at the level of the canines and upper incisors,
  • and an occlusal margin at each lateral dental area, ie at the level of the upper and lower premolars and molars on each side,
and which further comprises a removable pallet, made of a non-adaptable material, comprising a first zone intended to bear on the skeleton, preferably at the level of the incisivo-canine block, and not necessarily in direct contact, said zone of the pallet being dimensioned so that, during the adjustment phase of the GDP, the joint presence of said pallet and said skeleton makes it possible to guarantee both a ventilatory space and a sufficient presence of material at the level of the incisivo-canine block.

On entend par « matériau adaptable » le fait que le matériau devienne malléable pendant le procédé d'adaptation de la PIB.The term "adaptable material" means that the material becomes malleable during the process of adjusting the PIB.

On entend par « appui » que la palette coopère avec le squelette pour permettre à la fois une épaisseur suffisante de matériau au niveau du bloc incisivo-canin et un espace ventilatoire suffisant pour une bonne ventilation de l'utilisateur. Par conséquent, il peut exister une couche de matériau thermo-adaptable entre la palette et le squelette (ce qui implique un appui sans contact direct) sans amoindrir les effets de l'interaction entre la palette et le squelette.By "support" is meant that the pallet cooperates with the skeleton to allow both a sufficient thickness of material at the incisivo-canine block and a ventilatory space sufficient for good ventilation of the user. Therefore, there may be a layer of thermo-adaptable material between the pallet and the skeleton (which implies a non-direct contact support) without diminishing the effects of the interaction between the pallet and the skeleton.

L'adaptation de la PIB utilise, par exemple, une technique de thermo-adaptation par ramollissement du matériau à l'eau chaude pour permettre une adaptation à la bouche de l'utilisateur.The adaptation of the GDP uses, for example, a thermo-adaptation technique by softening the material with hot water to allow adaptation to the mouth of the user.

En l'absence du squelette, lorsque l'utilisateur serre les mâchoires pendant la procédure de mise en forme, les dents s'enfoncent dans la structure adaptable sans pouvoir maîtriser les épaisseurs. Si les épaisseurs de matériaux ne sont plus suffisantes, la PIB ne joue plus correctement son rôle. Le maintien des épaisseurs minimales, reproductibles pour tous les sportifs, favorise l'absorption et la dissipation de l'énergie d'impact par le matériau composite de la protection. Par ailleurs, en l'absence de la palette, l'écrasement des gouttières mandibulaire et maxillaire lors de l'adaptation de la PIB ne permet pas de conserver un espace antérieur suffisant pour une ventilation efficace de l'utilisateur.In the absence of the skeleton, when the user squeezes the jaws during the shaping procedure, the teeth sink into the adaptable structure without being able to control the thicknesses. If the thicknesses of materials are no longer sufficient, GDP no longer plays its role correctly. The maintenance of minimum thickness, reproducible for all athletes, promotes the absorption and dissipation of impact energy by the composite material of the protection. Moreover, in the absence of the pallet, the crushing of the mandibular and maxillary gutters during the adaptation of the PIB does not allow to preserve a previous space sufficient for an effective ventilation of the user.

On entend par « gouttière » le volume de matériau adaptable destiné à recevoir les arcades dentaires supérieure et inférieure. Ainsi, avant adaptation de la PIB, les gouttières supérieure et inférieure présentent des surfaces régulières, et après adaptation de la PIB, les gouttières supérieure et inférieure présentent les empreintes des dents.The term "gutter" means the volume of adaptable material for receiving the upper and lower dental arches. Thus, before adjustment of the GDP, the upper and lower gutters have regular surfaces, and after adjustment of the GDP, the upper and lower gutters present the fingerprints of the teeth.

Les gouttières présentent donc initialement des épaisseurs suffisantes afin que le matériau adaptable de la structure adaptable puisse combler un trou laissé par une dent manquante, et que toutes les dents soient bien recouvertes par le matériau adaptable pour être efficacement protégées, garantir la rétention de la PIB et solidariser l'arcade dentaire mandibulaire à l'arcade dentaire maxillaire.The gutters therefore initially have sufficient thicknesses so that the adaptable material of the adaptable structure can fill a hole left by a missing tooth, and that all the teeth are well covered by the adaptable material to be effectively protected, guarantee the retention of the GDP and secure the mandibular dental arch to the maxillary dental arch.

Cette première zone de la palette peut présenter différentes formes. Elle peut, par exemple, être plane, mais aussi plan-convexe ou biconvexe.This first area of the palette can have different shapes. It can, for example, be flat, but also plano-convex or biconvex.

La première zone de la palette présente ainsi une longueur L, une largeur l et une hauteur h. Une fois la PIB dans la bouche, on peut définir la longueur L comme la dimension s'étendant de l'extérieur vers l'intérieur de la bouche, la largeur l comme la dimension s'étendant d'une canine à l'autre, et la hauteur h est l'épaisseur de la palette, i.e. la dimension permettant de définir l'ouverture des mâchoires, l'espace laissé libre entre les dents maxillaires et les dents mandibulaires.The first zone of the pallet thus has a length L, a width l and a height h. Once the PIB in the mouth, we can define the length L as the dimension extending from the outside towards the inside of the mouth, the width l like the dimension extending from one canine to the other, and the height h is the thickness of the pallet, ie the dimension to define the opening of the jaws, the space left free between the maxillary teeth and the mandibular teeth.

Avantageusement, la première zone de la palette a une section transversale d'une surface environ égale ou supérieure à 30 millimètres carré.Advantageously, the first zone of the pallet has a cross section of a surface approximately equal to or greater than 30 millimeters squared.

L'espace ventilatoire ainsi créé est suffisant et nécessaire à une bonne ventilation de l'utilisateur, notamment pendant un effort. En dessous de cette valeur, l'utilisateur ne peut pas ventiler suffisamment et est alors amené à ouvrir la bouche, ce qui engendre les inconvénients précédemment cités.The ventilatory space thus created is sufficient and necessary for good ventilation of the user, especially during an effort. Below this value, the user can not ventilate enough and is then led to open the mouth, which causes the disadvantages mentioned above.

La fonction complémentaire entre la palette et le squelette non adaptables permet de répondre de façon efficace et reproductible aux deux principaux problèmes rencontrés dans les protections existantes, à savoir :

  • garantir la conservation d'épaisseurs minimales pour que la PIB assure de façon efficace l'absorption et la dissipation de l'énergie d'impact,
  • et conserver un espace suffisant pour la ventilation mâchoires serrées de l'utilisateur.
The complementary function between the pallet and the non-adaptable skeleton makes it possible to respond in an effective and reproducible way to the two main problems encountered in the existing protections, namely:
  • guarantee the conservation of minimum thicknesses for the GDP to efficiently absorb and dissipate impact energy,
  • and keep enough space for the user's tight jaw ventilation.

La présente invention répond ainsi aux propriétés reconnues essentielles pour ce dispositif :

  • occuper les espaces édentés.
  • permettre un engrènement des arcades dentaires mandibulaire et maxillaire.
  • être confortable.
  • ne pas présenter de saillie, ni de rugosité.
  • être rétentive.
  • absorber et dissiper l'énergie d'impact.
  • permettre la phonation.
  • permettre la ventilation buccale mâchoires serrées.
The present invention thus meets the recognized essential properties for this device:
  • occupy toothless spaces.
  • allow meshing of the mandibular and maxillary dental arches.
  • to be comfortable.
  • do not show protrusion or roughness.
  • to be retentive.
  • absorb and dissipate impact energy.
  • allow phonation.
  • allow oral ventilation tight jaws.

Avantageusement, la palette présente au moins un bras ayant une extrémité libre, par exemple deux bras, comportant un ergot, de préférence à l'extrémité libre, ledit ergot étant apte à s'insérer dans une fente prévue à cet effet dans la structure adaptable, de préférence au niveau d'un bourrelet occlusal, pour maintenir la position de la PIB lors de la phase d'adaptation, et ledit ergot pouvant rentrer en contact avec le squelette.Advantageously, the pallet has at least one arm having a free end, for example two arms, comprising a lug, preferably at the free end, said lug being able to fit into a slot provided for this purpose in the adaptable structure , preferably at an occlusal bead, to maintain the position of the PIB during the adaptation phase, and said pin can come into contact with the skeleton.

Avantageusement, la palette présente un bourrelet en arc de cercle, de préférence au niveau de la première zone, apte à venir en appui sur le bloc incisivo-canin. La butée créée par ce bourrelet permet de faciliter le positionnement des ergots dans leur fente lors de la mise en place de la palette. De plus, la présence conjointe du bourrelet en arc de cercle et des ergots permet de maintenir un bon positionnement de la palette lors de la phase d'adaptation, le bon positionnement de la palette étant nécessaire pour que le matériau adaptable des gouttières n'obstrue pas l'espace ventilatoire lors de l'adaptation de la PIB.Advantageously, the pallet has a bead in an arc of a circle, preferably at the level of the first zone, adapted to bear on the incisivo-canine block. The stop created by this bead facilitates the positioning of the lugs in their slot during the establishment of the pallet. In addition, the joint presence of the arcuate bead and lugs makes it possible to maintain a good positioning of the pallet during the adaptation phase, the correct positioning of the pallet being necessary for the adaptable material of the gutters does not obstruct not the ventilatory space when adapting the GDP.

Avantageusement, la palette présente une zone de préhension, par exemple, pour faciliter son extraction après mise en forme de la PIB.Advantageously, the pallet has a gripping zone, for example, to facilitate its extraction after shaping the GDP.

Selon un exemple de réalisation, la PIB présente une fenêtre, par exemple délimitée par le squelette et la gouttière inférieure, dans laquelle peut venir se loger la palette.According to an exemplary embodiment, the PIB has a window, for example delimited by the skeleton and the lower gutter, in which the pallet can be housed.

En effet, soit avant la mise en forme, la palette vient se loger dans une fenêtre qui lui est réservée pour maintenir un espace ventilatoire suffisant, soit une fois la structure adaptable ramollie pour l'adapter à la bouche d'un utilisateur, la palette vient créer ou augmenter un espace en s'enfonçant dans le matériau adaptable ramolli. Dans le cas où la PIB présente initialement une fenêtre, plusieurs modes de réalisation sont envisageables.Indeed, before formatting, the pallet is housed in a window reserved for it to maintain a sufficient ventilation space, or once the adaptable structure softened to adapt to the mouth of a user, the pallet creates or increases a space by sinking into softened adaptable material. In the case where the PIB initially has a window, several embodiments are possible.

Selon un premier mode de réalisation, la gouttière inférieure présente une discontinuité au niveau du bloc incisivo-canin. Cette discontinuité forme ainsi une fenêtre dans laquelle vient se positionner la palette qui est alors en appui sur le squelette, mais pas nécessairement en contact direct avec le squelette. La présence de la palette permet ainsi d'éviter que cet espace ne s'obstrue au moins partiellement pendant l'adaptation de la PIB par un utilisateur.According to a first embodiment, the lower gutter has a discontinuity at the incisivo-canine block. This discontinuity thus forms a window in which is positioned the pallet which is then supported on the skeleton, but not necessarily in direct contact with the skeleton. The presence of the pallet thus makes it possible to prevent this space from becoming clogged at least partially during the adjustment of the GDP by a user.

Selon un deuxième mode de réalisation, la gouttière inférieure est continue tout le long de l'arcade dentaire mandibulaire ; le squelette et la gouttière inférieure forment entre eux, à leur interface, une fenêtre dans laquelle la palette peut être insérée. Ainsi, les dents mandibulaires du bloc incisivo-canin peuvent aussi être protégées et l'espace ventilatoire antérieur conservé pendant la phase d'adaptation.According to a second embodiment, the lower groove is continuous all along the mandibular dental arch; the skeleton and the lower channel form between them, at their interface, a window in which the pallet can be inserted. Thus, the mandibular teeth of the incisivo-canine block can also be protected and the anterior ventilatory space preserved during the adaptation phase.

Selon un autre exemple de réalisation, la structure adaptable comprend un volet vestibulaire supérieur délimitant la gouttière supérieure destinée à recevoir l'arcade dentaire maxillaire.According to another exemplary embodiment, the adaptable structure comprises an upper vestibular flap delimiting the upper trough intended to receive the maxillary dental arch.

Selon un autre exemple de réalisation, la structure adaptable comprend un volet vestibulaire inférieur délimitant la gouttière inférieure destinée à recevoir l'arcade dentaire mandibulaire.According to another exemplary embodiment, the adaptable structure comprises a lower vestibular flap delimiting the lower gutter intended to receive the mandibular dental arch.

Avantageusement, le squelette comporte un arceau de fixation, par exemple au niveau du bloc incisivo-canin. Cet arceau peut servir, par exemple, à attacher la PIB à une grille de casque en football américain.Advantageously, the skeleton comprises a fixing arch, for example at the incisivo-canine block. This hoop can be used, for example, to attach the GDP to a helmet grid in American football.

Avantageusement, le squelette comprend des renforts frontaux. Ces renforts frontaux, de préférence situés au niveau supérieur du bloc incisivo-canin, permettent notamment de conserver la position et l'épaisseur du volet vestibulaire supérieur.Advantageously, the skeleton comprises frontal reinforcements. These frontal reinforcements, preferably located at the upper level of the incisivo-canine block, allow in particular to maintain the position and thickness of the upper vestibular flap.

Il peut être prévu également que le squelette comprenne des renforts latéraux, situés, de préférence, au niveau supérieur et/ou inférieur des bords extérieurs des secteurs latéraux.It can also be provided that the skeleton comprises lateral reinforcements, preferably located at the upper and / or lower level of the outer edges of the lateral sectors.

Les renforts frontaux et latéraux permettent ainsi de guider le bon positionnement des arcades dentaires maxillaire et mandibulaire de l'utilisateur dans les gouttières supérieure (maxillaire) et inférieure (mandibulaire) de la structure adaptable lors de la phase d'adaptation de la PIB à la morphologie de l'individu.The frontal and lateral reinforcements thus make it possible to guide the correct positioning of the maxillary and mandibular dental arches of the user in the upper (maxillary) and inferior (mandibular) grooves of the adaptable structure during the phase of adaptation of the PIB to the morphology of the individual.

Selon un autre exemple de réalisation, le squelette comprend au moins un trou d'ancrage, de préférence situé dans un des secteurs latéraux, pour assurer le maintien du squelette dans la structure adaptable. Ainsi, lors de la fabrication des PIB, généralement par surmoulage, les trous dans le squelette permettent une meilleure intégration du squelette dans le matériau adaptable de la structure adaptable.According to another embodiment, the skeleton comprises at least one anchor hole, preferably located in one of the lateral sectors, to ensure the maintenance of the skeleton in the adaptable structure. Thus, during the manufacture of PIBs, generally by overmolding, the holes in the skeleton allow a better integration of the skeleton in the adaptable material of the adaptable structure.

Selon encore un autre exemple de réalisation, les renforts frontaux sont reliés les uns aux autres par un élément de jonction, délimitant alors des espaces. Ces espaces permettent, à l'instar des trous d'ancrage des secteurs latéraux, de renforcer le maintien du squelette dans la structure adaptable au niveau du bloc incisivo-canin, ainsi que la forme du volet vestibulaire supérieur.According to yet another embodiment, the front reinforcements are connected to each other by a junction element, thus delimiting spaces. These spaces make it possible, like the anchoring holes of the lateral sectors, to reinforce the maintenance of the skeleton in the adaptable structure at the level of the incisivo-canine block, as well as the shape of the upper vestibular flap.

La présente invention comprend en outre un procédé d'utilisation.The present invention further comprises a method of use.

Une première étape préalable consiste à rendre malléable la structure adaptable, par exemple, en plaçant la PIB dans de l'eau chaude. Durant cette étape, la palette est positionnée à son emplacement pour maintenir la PIB et conserver les dimensions minimales de l'espace ventilatoire.A first preliminary step is to make malleable the adaptable structure, for example, by placing the GDP in hot water. During this stage, the pallet is positioned at its location to maintain the GDP and keep the minimum dimensions of the ventilatory space.

Une fois que la structure adaptable est devenue malléable, une deuxième étape consiste à placer la PIB dans la bouche de l'utilisateur qui serre les mâchoires et qui peut appuyer sur la PIB avec ses doigts et sa langue pour que la PIB prenne la forme des reliefs intra-oraux.Once the adaptable structure has become malleable, a second step is to place the GDP in the mouth of the user who squeezes the jaws and who can press GDP with his fingers and tongue so that the GDP takes the form of intraoral reliefs.

Ensuite, une troisième étape consiste à retirer la PIB de la bouche. De préférence, l'utilisateur attend quelques secondes avant de retirer la PIB de sa bouche afin que la structure adaptable ne se déforme plus.Then, a third step is to remove GDP from the mouth. Preferably, the user waits a few seconds before removing the PIB from his mouth so that the adaptable structure no longer deforms.

La PIB peut être refaçonnée à souhait à tout moment si l'utilisateur le considère nécessaire, en répétant les étapes précédentes.The PIB can be reshaped at will at any time if the user considers it necessary, by repeating the previous steps.

Enfin, lorsque la structure adaptable est en forme, une quatrième étape consiste à retirer la palette de la PIB. L'utilisateur peut ensuite replacer la PIB dans sa bouche pour vérifier l'adaptation, et, si besoin, recommencer les étapes précédentes.Finally, when the adaptable structure is in shape, a fourth step is to remove the pallet of GDP. The user can then place the GDP in his mouth to check the adaptation, and, if necessary, repeat the previous steps.

Dans le premier mode de réalisation selon lequel l'espace ventilatoire est principalement formé par une discontinuité de la gouttière inférieure, la palette est retirée en dégondant les ergots des extrémités libres des bras des fentes prévues à cet effet dans la structure adaptable.In the first embodiment in which the ventilatory space is mainly formed by a discontinuity of the lower gutter, the pallet is removed by disengaging the lugs of the free ends of the arms of the slots provided for this purpose in the adaptable structure.

Dans le deuxième mode de réalisation selon lequel l'espace ventilatoire est formé entre la gouttière inférieure et le squelette, les ergots des extrémités libres des bras sont d'abord dégondés des fentes prévues à cet effet dans la structure adaptable, puis les bras sont resserrés l'un vers l'autre par déformation élastique, et la palette est ensuite retirée en passant par l'espace ventilatoire.In the second embodiment in which the ventilatory space is formed between the lower trough and the skeleton, the lugs of the free ends of the arms are first disengaged from the slots provided for this purpose in the adaptable structure, then the arms are tightened. one to the other by elastic deformation, and the pallet is then withdrawn through the ventilatory space.

Ainsi, dans ce deuxième mode de réalisation, la palette peut présenter une géométrie plus échancrée au niveau de la jonction entre les bras afin de faciliter leur déformation élastique.Thus, in this second embodiment, the pallet may have a more indented geometry at the junction between the arms to facilitate their elastic deformation.

La PIB selon l'invention comporte une structure adaptable 1 et un squelette 2.The PIB according to the invention comprises an adaptable structure 1 and a skeleton 2.

Une PIB a généralement une forme qui reprend celle de l'arcade dentaire, i.e. qu'elle présente une zone en arc qui constitue le bloc incisivo-canin, et deux secteurs latéraux correspondant aux positions des prémolaires et des molaires.A PIB generally has a shape that resembles that of the dental arch, i.e. it has an arched area that constitutes the incisivo-canine block, and two lateral sectors corresponding to the positions of premolars and molars.

La structure adaptable 1 est réalisée dans un matériau adaptable, i.e. un matériau qui doit permettre à l'utilisateur d'adapter la PIB à sa morphologie buccodentaires, par exemple, par une technique de thermo-adaptation à l'eau chaude.The adaptable structure 1 is made of an adaptable material, i.e. a material which must allow the user to adapt the PIB to its oral morphology, for example, by a thermo-adaptation technique with hot water.

Dans le premier mode de réalisation décrit, la structure adaptable 1 présente une gouttière supérieure 122 destinée à recevoir l'arcade dentaire maxillaire, et une gouttière inférieure 121 destinée à recevoir l'arcade dentaire mandibulaire. La forme des gouttières maxillaire 122 et mandibulaire 121 de la structure adaptable 1 permet de combler de potentiels espaces édentés lors de la phase d'adaptation de la PIB à la morphologie buccodentaire de l'utilisateur.In the first embodiment described, the adaptable structure 1 has an upper gutter 122 for receiving the maxillary dental arch, and a lower gutter 121 for receiving the mandibular dental arch. The shape of the maxillary 122 and mandibular 121 gutters of the adaptable structure 1 makes it possible to fill potential edentulous spaces during the phase of adaptation of the PIB to the oral morphology of the user.

La structure adaptable 1 présente un bloc incisivo-canin 11 reliant deux secteurs latéraux 12 (un gauche et un droit). Lorsque la PIB est en bouche, le bloc incisivo-canin 11 est situé au niveau des canines et des incisives supérieures (maxillaires) et inférieures (mandibulaires), et les deux secteurs latéraux 12 sont situés de chaque côté, aux niveaux des prémolaires et molaires supérieures (maxillaires) et inférieures (mandibulaires).The adaptable structure 1 has an incisivo-canine block 11 connecting two lateral sectors 12 (a left and a right). When the GDP is in the mouth, the incisivo-canine block 11 is located at the level of the canines and the incisors upper (maxillary) and inferior (mandibular), and the two lateral sectors 12 are located on each side, at the levels of the premolars and upper molars (maxillary) and lower (mandibular).

La structure adaptable 1 comprend en outre un volet vestibulaire supérieur 111, qui délimite la gouttière supérieure 122 destinée à recevoir l'arcade dentaire maxillaire.The adaptable structure 1 further comprises an upper vestibular flap 111, which delimits the upper gutter 122 for receiving the maxillary dental arch.

Avantageusement, le volet vestibulaire supérieur 111 présente une échancrure 112 facilitant la position du frein de la lèvre supérieure.Advantageously, the upper vestibular flap 111 has a notch 112 facilitating the position of the brake of the upper lip.

La structure adaptable 1 peut, selon un deuxième mode de réalisation représenté figure 1 b), comprendre aussi un volet vestibulaire inférieur 114, qui délimite alors la gouttière inférieure 121 destinée à recevoir l'arcade dentaire mandibulaire.The adaptable structure 1 may, according to a second embodiment shown Figure 1 (b) , also include a lower vestibular flap 114, which then delimits the lower groove 121 for receiving the mandibular dental arch.

Selon un premier exemple de réalisation, la structure adaptable 1 présente une fenêtre 113, délimitée par le squelette 2 et la gouttière inférieure 121 discontinue (voire du volet vestibulaire inférieur 114 s'il s'agit du deuxième mode de réalisation), dans laquelle peut venir se loger une palette 3 destinée à maintenir un espace ventilatoire suffisant lors de la mise en forme de la PIB, en permettant de conserver des épaisseurs minimales.According to a first exemplary embodiment, the adaptable structure 1 has a window 113 delimited by the skeleton 2 and the discontinuous lower gutter 121 (or even the lower vestibular flap 114 if it is the second embodiment), in which come to lodge a pallet 3 intended to maintain a sufficient ventilatory space during the shaping of the PIB, while allowing to maintain minimum thicknesses.

La forme de la structure adaptable 1 est alors conforme à la morphologie buccodentaire standardisée (profondeur des volets vestibulaires supérieur (maxillaire) 111, et inférieur (mandibulaire) 114 s'il existe, position de l'échancrure 112, largeur et longueur de l'arcade, etc.).The shape of the adaptable structure 1 is then in accordance with the standardized oral morphology (depth of the vestibular flap upper (maxillary) 111, and lower (mandibular) 114 if it exists, position of the notch 112, width and length of the arcade, etc.).

Le squelette 2 est inclus dans la structure adaptable 1. Il est constitué de préférence d'un matériau de texture non modifiable (ou modelable) par la technique préconisée pour adapter la structure adaptable 1 à la morphologie buccodentaire de l'utilisateur (technique par thermo-adaptation à l'eau chaude ou autres techniques).The skeleton 2 is included in the adaptable structure 1. It is preferably composed of a non-modifiable (or modelable) texture material by the technique recommended for adapting the adaptable structure 1 to the oral morphology of the user (thermo technique). -adaptation to hot water or other techniques).

Ainsi, lors de l'adaptation en bouche après ramollissement de la structure adaptable 1, le squelette 2 permet de garantir la conservation, dans les zones à risque de traumatismes, des épaisseurs de matériau minimales nécessaires pour l'absorption et la dissipation de l'énergie de l'impact traumatique.Thus, during the adaptation in the mouth after softening of the adaptable structure 1, the skeleton 2 makes it possible to guarantee the conservation, in the areas at risk of trauma, of the minimum thicknesses of material necessary for the absorption and the dissipation of the energy of traumatic impact.

Le squelette 2 présente également un bloc incisivo-canin 21 et deux secteurs latéraux 22 (un gauche et un droit). Comme pour la structure adaptable 1, lorsque la PIB est en bouche, le bloc incisivo-canin 21 est situé au niveau des canines et des incisives supérieures (maxillaires) et inférieures (mandibulaires), les secteurs latéraux 22 étant situés de chaque côté, aux niveaux des prémolaires et molaires supérieures (maxillaires) et inférieures (mandibulaires).The skeleton 2 also has an incisivo-canine block 21 and two lateral sectors 22 (a left and a right). As for the adaptable structure 1, when the PIB is in the mouth, the incisivo-canine block 21 is located at the level of the canines and upper (maxillary) and lower (mandibular) incisors, the lateral sectors 22 being located on each side, at the levels of premolars and upper (maxillary) and lower (mandibular) molars.

Selon le présent exemple de réalisation, le squelette 2 présente plusieurs renforts.According to the present embodiment, the skeleton 2 has several reinforcements.

Au niveau du bloc incisivo-canin 21, le squelette 2 présente trois renforts frontaux 211, mais non nécessairement exclusivement. La forme et la position de ces renforts frontaux 211 permet, tout d'abord, que la PIB conserve une épaisseur suffisante au niveau des incisives et des canines, ensuite, de contribuer à la conservation de la forme du volet vestibulaire supérieur 111 lorsque le matériau de la structure adaptable a été ramolli, enfin de guider le bon positionnement des incisives maxillaires lors de la procédure d'adaptation.At the incisivo-canine block 21, the skeleton 2 has three frontal reinforcements 211, but not necessarily exclusively. The shape and the position of these frontal reinforcements 211 allow, first of all, that the PIB keeps a sufficient thickness at the level of the incisors and the canines, then, to contribute to the conservation of the shape of the upper vestibular flap 111 when the material adaptable structure was softened, finally to guide the correct positioning of the maxillary incisors during the adaptation procedure.

Selon un exemple de réalisation, les renforts frontaux 211 du bloc incisivo-canin 21 sont reliés les uns aux autres par un élément 212 de jonction destiné à renforcer la solidarisation des renforts frontaux 211 et le maintien du volet vestibulaire supérieur 111.According to an exemplary embodiment, the front reinforcements 211 of the incisivo-canine block 21 are connected to each other by a connecting element 212 for reinforcing the joining of the front reinforcements 211 and maintaining the upper vestibular flap 111.

Le squelette 2 comprend aussi des renforts latéraux supérieurs 222 et inférieurs 223, de préférence au niveau des bords extérieurs des secteurs latéraux 22.The skeleton 2 also comprises upper lateral reinforcements 222 and lower 223, preferably at the outer edges of the lateral sectors 22.

Ces renforts latéraux supérieurs 222 et inférieurs 223 peuvent être une bande continue de matière ou des plots. Dans l'exemple illustré sur la figure 6, le squelette 2 comporte des renforts latéraux supérieurs 222 se présentant sous forme de bande continue, et des renforts latéraux inférieurs (223a, 223b, 223c, 223d) sous forme de plots.These upper lateral reinforcements 222 and lower 223 may be a continuous band of material or pads. In the example shown on the figure 6 , the skeleton 2 comprises upper lateral reinforcements 222 in the form of a continuous strip, and lower lateral reinforcements (223a, 223b, 223c, 223d) in the form of pads.

Le squelette 2 comprend également des trous d'ancrage 221 dans les secteurs latéraux 22, voire des espaces 214 dans le bloc incisivo-canin 21 dans le cas où un élément 212 de jonction est présent. En effet, selon un mode préférentiel de réalisation, le squelette 2 est confectionné, par exemple par moulage, puis la structure adaptable 1 est obtenue par surmoulage. La présence des trous d'ancrage 221 dans les secteurs latéraux 22 du squelette 2, voire dans certains cas des espaces 214 au niveau du bloc incisivo-canin, permet une meilleure intégration du squelette 2 dans le matériau adaptable de la structure adaptable 1.The skeleton 2 also comprises anchor holes 221 in the lateral sectors 22, or even spaces 214 in the incisivo-canine block 21 in the case where a joining element 212 is present. Indeed, according to a preferred embodiment, the skeleton 2 is made, for example by molding, and the adaptable structure 1 is obtained by overmolding. The presence of the anchoring holes 221 in the lateral sectors 22 of the skeleton 2, or in some cases spaces 214 at the level of the incisivo-canine block, allows a better integration of the skeleton 2 in the adaptable material of the adaptable structure 1.

Selon encore un autre exemple de réalisation, le squelette 2 présente également un arceau 213 au niveau du bloc incisivo-canin 21 qui peut être utilisé pour attacher la PIB à une grille de casque en football américain par exemple.According to yet another embodiment, the skeleton 2 also has a hoop 213 at the incisivo-canine block 21 which can be used to attach the GDP to a helmet grid in American football for example.

La PIB comporte en outre une palette 3 amovible réalisée, de préférence, dans un matériau rigide et de texture non modifiable (ou modelable) par la technique préconisée pour adapter la structure adaptable à la morphologie buccodentaire de l'utilisateur (technique par thermo-adaptation à l'eau chaude ou autres techniques).The PIB further comprises a removable pallet 3 preferably made of a rigid material of non-modifiable (or modelable) texture by the technique recommended for adapting the adaptable structure to the oral morphology of the user (thermo-adaptation technique with hot water or other techniques).

L'ajustement de la palette 3 avec le squelette 2 contribue au guidage de l'arcade dentaire maxillaire de l'utilisateur dans la gouttière supérieure (maxillaire) 122 de la structure adaptable 1 lors de la phase d'adaptation de la PIB à la morphologie buccodentaire du sujet.The adjustment of the pallet 3 with the skeleton 2 contributes to the guidance of the maxillary dental arch of the user in the upper (maxillary) groove 122 of the adaptable structure 1 during the phase of adaptation of the PIB to the morphology the subject.

La palette 3 présente principalement une première zone 33 apte à coopérer avec le squelette 2 pour préserver un espace ventilatoire suffisant tout en permettant la conservation des épaisseurs de la protection.The pallet 3 has mainly a first zone 33 adapted to cooperate with the skeleton 2 to preserve a sufficient ventilation space while allowing the preservation of the thicknesses of the protection.

Ladite zone 33 est dimensionnée de sorte que, lors de la phase d'adaptation de la PIB, le positionnement de cette zone 33 au niveau du bloc incisivo-canin, dans l'espace 113 lorsqu'il existe, et en coopération avec le squelette 2, permet de conserver, voire de créer ou d'agrandir, un espace ventilatoire antérieur de dimensions suffisantes lors de la phase d'adaptation de la PIB à la morphologie buccodentaire de l'utilisateur, pour que ce dernier puisse bénéficier d'une ventilation efficace en position mâchoires serrées, par exemple lors d'une activité sportive. Cette première zone 33 présente en particulier, dans la zone d'intersection entre la palette 3 et le bloc incisivo-canin (lorsque la palette 3 est en place pour l'adaptation de la PIB), une section transversale 331 définie par une largeur l et une hauteur h minimales (figure, 8a), 8b), 10 et 11). Les dimensions de l'espace ventilatoire sont donc garanties par les dimensions de cette plus petite section transversale 331 de cette première zone 33.Said zone 33 is dimensioned so that, during the phase of adaptation of the PIB, the positioning of this zone 33 at the level of the incisivo-canine block, in the space 113 when it exists, and in cooperation with the skeleton 2, makes it possible to preserve, or even create or enlarge, an anterior ventilatory space of sufficient dimensions during the phase of adaptation of the PIB to the oral morphology of the user, so that the latter can benefit from a ventilation effective in tight jaw position, for example during a sports activity. This first zone 33 presents, in particular, in the zone of intersection between the pallet 3 and the incisivo-canine block (when the pallet 3 is in place for the adaptation of the PIB), a cross section 331 defined by a width l and a minimum height h ( figure, 8a), 8b), 10 and 11 ). The dimensions of the ventilatory space are thus guaranteed by the dimensions of this smaller cross section 331 of this first zone 33.

Avantageusement, cette section transversale 331 devra être conçue de façon à maintenir, après la procédure de mise en forme de la PIB, un espace ventilatoire antérieur d'une section environ égale ou supérieure à 30 millimètres carré.Advantageously, this cross section 331 should be designed to maintain, after the GDP shaping procedure, an anterior ventilatory space of a section equal to or greater than 30 millimeters squared.

Par exemple, cette section transversale 331 est conçue pour laisser passer, après mise en forme, un gabarit de dimensions suivantes :

  • hauteur h : 2 mm,
  • largeur l : 15 mm.
For example, this cross section 331 is designed to pass, after shaping, a template of the following dimensions:
  • height h: 2 mm,
  • width l: 15 mm.

La palette 3 présente, selon un exemple préférentiel de réalisation, deux bras 34, un bras gauche 341 et un bras droit 342, terminés chacun par un ergot (343, 344), chaque ergot (343, 344) étant apte à s'insérer dans des fentes prévues à cet effet dans les secteurs latéraux 12 de la structure adaptable 1 et à prendre appui sur les secteurs latéraux 22 du squelette 2 (non nécessairement en contact direct) afin de maintenir la palette 3 en position lors de la phase d'adaptation de la PIB.The pallet 3 has, according to a preferred embodiment, two arms 34, a left arm 341 and a right arm 342, each terminated by a lug (343, 344), each lug (343, 344) being adapted to be inserted in slots provided for this purpose in the lateral sectors 12 of the adaptable structure 1 and to bear on the lateral sectors 22 of the skeleton 2 (not necessarily in direct contact) to maintain the pallet 3 in position during the phase of adjustment of GDP.

La jonction (345 ou 346) de ces deux bras 341 et 342 peut prendre différentes formes : par exemple, la jonction 345 sera plus rigide que la jonction 346. La jonction 346 permet, par exemple, de faciliter l'insertion et l'extraction de la palette lorsque l'espace 113 est formé à l'interface entre la gouttière inférieure 121 continue et le squelette 2 (par exemple, lorsque la PIB est réalisée selon le deuxième mode de réalisation).The junction (345 or 346) of these two arms 341 and 342 can take different forms: for example, the junction 345 will be more rigid than the junction 346. The junction 346 makes it possible, for example, to facilitate insertion and extraction. of the pallet when the space 113 is formed at the interface between the lower continuous trough 121 and the skeleton 2 (for example, when the PIB is produced according to the second embodiment).

La palette 3 présente aussi un bourrelet 32 en arc de cercle qui est, de préférence, précisément ajusté au rebord du bloc incisivo-canin 11 de la structure adaptable 1 pour faciliter le positionnement des ergots (343, 344) dans les fentes lors de la mise en forme dans la bouche, et maintenir ainsi la position de la zone 33 par exemple lors de la phase d'adaptation.The pallet 3 also has a bead 32 in an arc which is preferably precisely fitted to the rim of the incisivo-canine block 11 of the adaptable structure 1 to facilitate the positioning of the lugs (343, 344) in the slots during the formatting in the mouth, and thus maintain the position of the zone 33 for example during the adaptation phase.

Avantageusement, la palette 3 présente une zone de préhension 31.Advantageously, the pallet 3 has a gripping zone 31.

La PIB peut enfin être réalisée selon les méthodes classiquement employées. En particulier, le squelette, réalisé par exemple par moulage, est positionné dans un moule dans lequel le matériau de la structure adaptable est injecté. La structure adaptable peut par conséquent, in fine, présenter des petits trous correspondant à des plots présents dans le moule pour maintenir le squelette en place lors de l'injection du matériau de la structure adaptable.The GDP can finally be realized according to the methods conventionally used. In particular, the skeleton, made for example by molding, is positioned in a mold in which the material of the adaptable structure is injected. The adaptable structure can therefore ultimately have small holes corresponding to the pads present in the mold to maintain the skeleton in place during the injection of the material of the adaptable structure.

Naturellement, diverses variantes de réalisation sont possibles, sans pour autant sortir du cadre de l'invention.Naturally, various alternative embodiments are possible, without departing from the scope of the invention.
