Abstract

La présente invention concerne un appareil orthodontique destiné à déplacer plusieurs dents, comprenant : un fil d'arc orthodontique disposé sur les dents à corriger sur les régions incisive et molaire ; et une unité de ressort d'entraînement reliée à l'arc et déplaçant simultanément ou successivement les dents le long d'un arc dentaire vers la région incisive ou molaire. Contrairement à l'état de la technique, la présente invention permet de déplacer plusieurs dents de manière simultanée ou liée vers l'intérieur de la cavité buccale car les dents dans une zone molaire et les dents dans les zones incisive et prémolaire se restreignent les unes les autres au moyen d'un fil, ce qui réduit la durée de traitement orthodontique, et permet de créer une force orthodontique dans la direction de déplacement des dents, ce qui réduit encore davantage la durée de traitement orthodontique.
