The invention is an oral appliance for prevention of sleeping problems including snoring, sleep apnea and bruxism. Specifically, the appliance alters the position of the user's mandible, which is known as a method for reducing the restriction of the flow of air through the pharyngeal passageway. The appliance is a one-piece device molded from a flexible polymer such as Kraton ®. It includes an upper maxillary tray and a lower mandibulary tray. Both upper and lower trays include inner and outer walls which increase contact area with the teeth.. The hinge mechanism of the device includes a positive positioning system comprised of opposed interlocking ridges. The ridges serve to create offset between the position of the upper tray and lower tray relative to each other, therefore advancing the user's mandible. Additional features include airflow posts to keep the mouthpiece from sealing completely, a cleft contour, and a tooth retention tab.
La présente invention concerne un appareil buccal pour la prévention de problèmes du sommeil comprenant le ronflement, lapnée du sommeil et le bruxisme. En particulier, lappareil modifie la position de la mâchoire inférieure de lutilisateur, qui est un procédé connu pour réduire la restriction de lécoulement de lair à travers le passage du pharynx. Lappareil est un dispositif monobloc moulé à partir dun polymère souple tel que le Kraton®. Il comporte un plateau maxillaire supérieur et un plateau maxillaire inférieur. Les plateaux maxillaires supérieur et inférieur comportent des parois interne et externe qui accroissent la zone de contact avec les dents. Le mécanisme de charnière du dispositif comporte un système de positionnement positif comportant des arêtes de verrouillage. Les arêtes servent à créer un décalage entre la position mutuelle du plateau supérieur et du plateau inférieur, et donc permettent lavancement de la mâchoire inférieure de lutilisateur. Des éléments additionnels comprennent des tenons découlement dair pour empêcher la fermeture complète de lembout, un contour du palais, et une languette de retenue des dents.
