Abstract

L'invention concerne un appareil orthodontique basé sur une structure relativement simple, réduisant le temps nécessaire pour une opération et réduisant une sensation de corps étranger d'un porteur, un appareil pour redresser les dents à l'aide d'un fil orthodontique comprend : un appareil de type A, dans lequel une fente pour soutenir le fil orthodontique est formée à un angle de dépression ; et un appareil de type B, dans lequel une fente pour soutenir le fil orthodontique est formée à un angle d'élévation, l'angle de dépression de l'appareil de type A étant formé de telle sorte que la hauteur avec une base est la même que celle de la base ou diminue lorsqu'on s'approche de l'extrémité extérieure de la fente à son extrémité intérieure, et l'angle d'élévation de l'appareil de type B étant formé de telle sorte que la hauteur avec la base est la même que celle de la base ou augmente lorsqu'on s'approche de l'extrémité extérieure de la fente à son extrémité intérieure. Par conséquent, le temps nécessaire pour une opération est réduit, tout en éliminant un facteur d'augmentation de coût, et une commodité orthodontique peut être améliorée en réduisant la sensation de corps étranger du porteur.
