Abstract

Le dispositif orthodontique de type gouttière de la présente invention comporte un support (1) qui est pris en sandwich entre les rangées de dents (61, 71) de la mâchoire supérieure (6) et de la mâchoire inférieure (7) et qui est en forme de U selon une vue planaire ; une paroi périphérique extérieure située du côté de la mâchoire supérieure (2), qui fait saillie vers le haut depuis le bord périphérique extérieur du support (1) et entre en contact avec la lèvre supérieure (62) depuis sa face interne ; une paroi périphérique extérieure située du côté de la mâchoire inférieure (3), qui fait saillie vers le bas depuis le bord périphérique extérieur du support (1) et entre en contact avec la lèvre inférieure (72) depuis sa face interne et avec la partie correspondant aux dents de devant (711) de la mâchoire inférieure (7) depuis sa face externe ; et une paroi périphérique intérieure située du côté de la mâchoire supérieure (4), qui fait saillie vers le haut depuis le bord périphérique intérieur du support (1) et entre en contact avec la partie correspondant aux dents de devant (611) de la mâchoire supérieure (6) depuis sa face interne. La surface périphérique intérieure de la paroi périphérique extérieure située du côté de la mâchoire supérieure (2) et la surface périphérique extérieure de la paroi périphérique intérieure située du côté de la mâchoire supérieure (4) sont espacées l'une de l'autre selon une distance supérieure à l'épaisseur de la rangée de dents (61) de la mâchoire supérieure (6). En conséquence, le prognathisme mandibulaire est amené à disparaître ou à s'atténuer même durant la période de la dentition permanente.
