Abstract[English]
The A device for laterally expanding a patient's palate, featuring a longitudinally extending screw with at least one threaded end. A first gear is mounted on the screw, coupled to a second gear that receives torque from a tool. Rotation of the second gear causes the screw to turn, moving front and back nuts in opposite longitudinal directions. These nuts are pivotally connected to left and right linkages, which move laterally when the nuts approach each other. Pads attached to the linkages are configured to secure anchoring mechanisms that apply lateral force on a patient's teeth during expansion. The device can be enclosed in a housing that guides the movement of internal components, with the pads protruding from the sides during expansion. The design ensures effective, controlled, and symmetrical palatal expansion, with potential customization for patient comfort and fit.[French]
L'invention concerne un appareil A d'expansion latérale du palais d'un patient, comprenant une vis s'étendant longitudinalement avec au moins une extrémité filetée. Un premier engrenage est monté sur la vis, couplé à un second engrenage qui reçoit un couple d'un outil. La rotation du second engrenage amène la vis à tourner, en déplaçant des écrous avant et arrière dans des directions longitudinales opposées. Ces écrous sont reliés de manière pivotante à des liaisons gauche et droite, qui se déplacent latéralement lorsque les écrous se rapprochent l'un de l'autre. Des patins fixés aux liaisons sont configurés pour fixer des mécanismes d'ancrage qui appliquent une force latérale sur les dents d'un patient pendant l'expansion. L'appareil peut être enfermé dans un boîtier qui guide le mouvement de composants internes, les patins faisant saillie à partir des côtés pendant l'expansion. La conception assure une expansion palatine efficace, contrôlée et symétrique, avec une personnalisation possible du confort et de l'ajustement du patient.
