Title (EN) BRACKET FOR CORRECTING SET OF TEETH
(FR) APPAREIL ORTHODONTIQUE
Abstract:
(EN) A bracket for correcting a set of teeth, which comprises a substrate (1), a wire insertion groove (3) for receiving slidably a correcting wire and a wire support (2) having a pair of anchor pawls (10a) and (10b) for a ligature wire each on each of both of its side portions. At least one of the anchor pawls is formed without both end portions in its longitudinal direction so that the ligature wire can be run from one of the anchor pawls to the other through the upper surface of the end portion of the wire support and the correcting wire is not directly pressed by the ligature wire, thus ensuring a smooth sliding motion of the correcting wire.
(FR) Un appareil orthodontique comprend un substrat (1), une rainure (3) d'insertion d'un fil métallique qui reçoit, en le glissant, un fil métallique orthodontique ainsi qu'un support (2) du fil métallique ayant une paire de cliquets d'ancrage (10a et 10b) d'un fil de ligature, chaque cliquet d'ancrage étant agencé sur chaque côté du support. Au moins un des cliquets d'ancrage est dépourvu de ses deux extrémités longitudinales, de sorte que l'on puisse étendre le fil de ligature d'un cliquet d'ancrage à l'autre à travers la surface supérieure de la partie terminale du support du fil, le fil métallique orthodontique n'étant pas directement comprimé par le fil de ligature, ce qui permet au fil orthodontique de glisser sans difficulté.
