Patent
CA 2424055
A device for delivering medicaments to oral structures contains a flexible backing having a plurality of microstructures protruding from one surface of the backing, and a binder layer containing medicaments disposed on the backing and/or microstructures. Because the device contains microstructures that form obstacles or barrier that minimize the flow of medicaments away from the target oral structure, the medicaments stay at the desired longer thereby being more effective at treating the oral structure. One particularly useful application of the inventive device is for whitening teeth.
L'invention concerne un dispositif servant à administrer des médicaments à des structures orales. Ce dispositif comprend un support souple présentant plusieurs microstructures en saillie à partir d'une surface du support, ainsi qu'une couche de liaison renfermant des médicaments disposés sur le support et/ou les microstructures. Du fait que le dispositif comprenne des microstructures créant des obstacles ou barrière minimisant le flux de médicaments à distance de la structure orale cible, les médicaments restent à l'emplacement souhaité plus longtemps et sont ainsi plus efficaces pour le traitement de la structure orale cible. On peut citer à titre d'application particulièrement utile de l'invention, le blanchiment des dents.
