Definitions

  • the present invention relates to a device for orthodontic toothing, and more particularly to a dental orthodontic device in which a bracket and an archwire are combined.
  • Begg technology There are many types of orthodontic devices, the most commonly used are Begg technology and square wire technology.
  • the combination of Begg technology and square wire bow technology has produced Tip-edge technology, and the square wire bow technology has developed the straight wire bow technology that is now commonly used.
  • the square wire bow technique and the straight wire bow technique use an archwire slot running through the near and far direction, and the Begg technique uses an archwire slot penetrating in the vertical direction. Therefore, the Begg technology allows the teeth to be tilted at a greater angle, while the square wire technique and the straight wire technique allow for limited tilting movements only if the width of the archwire is significantly smaller than the width of the archwire slot.
  • Begg technology and Tip-edge technology require additional positive-axis springs or additional archwires to control the roots during the root-moving tooth stage.
  • the operation is inconvenient, and the structure is too complicated. It is not widely used in clinical practice.

Abstract

L'invention porte sur un ensemble orthodontique qui comprend un tube de molaire, un boîtier orthodontique, un arc dentaire (28) et un dispositif de ligature (27). Des fentes d'arc dentaire (3, 16) sont formées dans une direction mésiodistale dans le boîtier et dans le tube de molaire. Au moins une fente supplémentaire (7, 21) est formée dans la paroi latérale de la fente d'arc dentaire du boîtier et du tube de molaire et s'ouvre au niveau de la fente d'arc dentaire. Chaque fente supplémentaire démarre à partir du bord mésial ou du bord distal de la paroi latérale de la fente d'arc dentaire. Une fente supplémentaire (10) est formée au niveau de la paroi inférieure de la fente de fil métallique d'arcade et débouche au niveau de la fente d'arc dentaire. L'angle d'intersection du bord mésial de la paroi latérale et de la paroi inférieure de la fente d'arc dentaire est un angle aigu et l'angle d'intersection du bord distal de la paroi latérale et de la paroi inférieure de la fente d'arc dentaire est un angle aigu, ce qui constitue une aide pour déplacer l'arc dentaire le long de la fente d'arc dentaire après ligature. Différents arcs dentaires sont utilisés, et différentes procédures de ligature sont adoptées conjointement, lesquelles commandent la position de l'arc dentaire dans la fente d'arc dentaire et le déplacement de l'arc dentaire dans et à l'extérieur des fentes supplémentaires, de telle sorte que les dents peuvent bouger de manière oblique dans la direction mésiodistale seulement sous une légère force et que les actions de redressement de racine peuvent être effectuées facilement dans les directions à la fois bucco-linguale et mésiodistale sans arc dentaire supplémentaire.
