Abstract

La présente invention concerne un appareil orthodontique de déplacement de dent comprenant : un fil métallique d'arc disposé le long d'une trajectoire correspondant à un profil de dents devant être alignées sur une région antérieure et une région postérieure ; et une unité de ressort d'entraînement raccordé au fil d'arc et déplaçant une dent du côté de région postérieure et une dent du côté de région antérieure vers l'intérieur d'une cavité buccale le long d'une trajectoire de dentition. Contrairement à la technologie conventionnelle, la présente invention permet de déplacer simultanément une pluralité de dents ou d'une façon interactive vers l'intérieur d'une cavité buccale tandis qu'une dent d'un côté de région postérieure et une dent d'un côté de région antérieure sont reliées l'une à l'autre par un fil métallique, et peut ainsi diminuer le temps de traitement orthodontique. En outre, la présente invention permet de générer une force orthodontique dans une direction de déplacement de dent, et peut ainsi réduire le temps de traitement orthodontique.
