Abstract

La présente invention concerne un support orthodontique comprenant : une base qui comprend une partie fixe fixée à des dents, une partie de support s'étendant sur la partie fixe, et une partie de rail formant, conjointement avec la partie de support, une partie d'attache de fil ayant un fil attaché ; un corps élastique qui est formé à partir d'un matériau métallique flexible et qui est disposé sur la partie de rail, de telle sorte qu'une région de ce dernier fasse saillie ; et un capuchon qui forme une pluralité de rainures de couplage couplées de manière sélective au corps élastique, recouvre la partie de rail et est disposé de façon à pouvoir se déplacer par coulissement sur la partie de rail de façon à ouvrir/fermer la partie d'attache de fil. Lorsque le corps élastique est sélectivement couplé à n'importe quelle rainure de couplage parmi la pluralité de rainures de couplage, le corps élastique est couplé à la rainure de couplage dans un état de déformation élastique et produit ainsi un effet haptique sur le capuchon.
