Abstract

L'invention porte sur un dispositif orthodontique de fixation côté palais qui peut être attaché et détaché facilement d'un palais. Le dispositif de fixation est équipé d'un élément d'attache au palais (3) qui est attaché de manière amovible au palais. L'élément d'attache au palais a une paire d'éléments souples (4). La paire d'éléments souples s'étend dans la même direction et les extrémités adjacentes de ceux-ci au niveau d'un côté sont assemblées ensemble, permettant ainsi de former un joint. Le côté de joint de l'élément d'attache au palais forme une première partie d'attache qui définit un espace (S1) assez large de telle sorte qu'un implant puisse être inséré de manière mobile dans l'espace (S1) et qui est équipé d'une partie contiguë (6) destinée à être en butée et à empêcher ainsi le déplacement de l'implant disposé dans l'espace (S1) lorsque l'implant se déplace loin des extrémités avant (4a) de la paire d'éléments souples. Les côtés de la paire d'éléments souples comprenant les extrémités avant (4a) ont un espacement entre elles qui diminue avec la diminution de la distance à partir des extrémités avant, et ces côtés de la paire d'éléments souples forment une partie de support souple apte à prendre en sandwich et à maintenir l'autre implant par l'application d'une force polarisée vers le joint sous la force élastique de la paire d'éléments souples.
