Title (EN) LINGUAL ORTHODONTIC APPLIANCE
(FR) APPAREIL ORTHODONTIQUE LINGUAL
Abstract:
(EN) A lingual orthodontic appliance contains a lingual bracket (12) for an anterior tooth and an archwire (20). The orthodontic appliance is defined in a three-dimensional Cartesian coordinate system. The archwire (20) extends in a first and a second dimension of the coordinate system generally U-shaped. In the third dimension the archwire (20) is generally flat. The archwire (20) has a rectangular cross-section with a height defined by the longer side of the rectangular cross-section. The height is oriented along the third dimension. The bracket further has a bracket pad (2) and a bracket body (1). The bracket body (1) forms a slot (4) for receiving the archwire (20). The slot (4) is formed by at least two opposing parallel slot side faces and a slot ground face arranged perpendicular thereto. The slot (4) has a width defined by the distance between the slot side faces. The width matches with the height of the archwire (20). The invention is advantageous for an orthodontic treatment of teeth requiring good tip and rotation control.
(FR) La présente invention concerne un appareil orthodontique lingual qui contient un bracket lingual (12) pour une dent antérieure et un arc orthodontique (10). L'appareil orthodontique est défini dans un système de coordonnées cartésiennes à trois dimensions. L'arc orthodontique (20) s'étend dans une première et une seconde dimension du système de coordonnées généralement en forme de U. Dans la troisième dimension, l'arc orthodontique (20) est généralement plat. L'arc orthodontique (20) a une section transversale rectangulaire avec une hauteur définie par le côté plus long de la section transversale rectangulaire. La hauteur est orientée selon la troisième dimension. Le bracket comprend en outre un tampon (2) de bracket et un corps (1) de bracket. Le corps (1) de bracket forme une fente (4) destinée à recevoir l'arc orthodontique (20). La fente (4) est formée par au moins deux faces latérales parallèles opposées de fente et une face inférieure de fente disposée perpendiculairement à celles-ci. La fente (4) présente une largeur définie par la distance entre les faces latérales de fente. La largeur correspond à la hauteur de l'arc orthodontique (20). L'invention est avantageuse pour un traitement orthodontique des dents nécessitant une bonne commande de la pointe et de la rotation.
