Abstract

L'invention concerne un boîtier orthodontique lingual (1) dans lequel la section centrale (13) d'une surface inférieure de fente (4a) est renfoncée par rapport aux deux sections d'extrémité (11, 12) dans la direction longitudinale de fente, vu selon la direction longitudinale de fente. Un contact à point unique, dans lequel une partie courbée d'un arc dentaire (W) est en contact uniquement avec la section centrale (13) de la surface inférieure de fente (4a), est empêché et il est ainsi possible de former un état de contact à deux points dans lequel ledit arc dentaire (W) est en contact avec les deux sections d'extrémité (11, 12). La présente invention permet un limitation facile et fiable de la rotation des dents avant. De plus, un frottement entre l'arc dentaire et le boîtier orthodontique lingual est réduit, et il est ainsi possible d'augmenter la vitesse de mouvement des dents avant.
