Abstract

La présente invention a pour objet un ancrage palatal absolu pour le redressement des dents dans un acte de traction linguale. L'ancrage palatal absolu pour le redressement des dents selon la présente invention comprend : un corps d'ancrage à travers lequel un trou de vissage passe de sorte à être fixé à un palais à l'aide d'une vis et un crochet disposé sur le corps d'ancrage et relié à un organe de traction. Le crochet comporte une pluralité de parties de liaison de l'organe de traction pour déterminer différemment un point et une direction d'application d'une force de traction. Selon la présente invention, les parties de liaison de l'organe de traction peuvent avoir une position variable, et une opération de connexion de l'organe de traction peut être réalisée facilement dans un espace étroit à l'intérieur d'une cavité buccale. Selon les besoins, du fait que le point et la direction d'application de la force de traction peuvent être ajustés, on peut améliorer la précision de l'orthodontie et la commodité d'un acte. En outre, la sollicitation des patients peut être réduite.
