(EN) The present invention relates to a controlled release device for oral cavity, which is attached on a hard dental surface of a tooth. The attachment is done using any adhesive layer that can attach on enamel surface of a tooth or using a holder attached to the hard dental surface, to which holder the device can be attached, clipped or fastened. The device comprises of two or more polymeric materials forming a polymer matrix or matrices. The polymer matrices incorporate one or more agent(s), which release rate in the oral cavity can be con-trolled with the polymeric materials in the matrices. The invention also relates to a method producing a controlled re-lease device for delivering an agent to the oral cavity.
(FR) La présente invention concerne un dispositif de libération contrôlée pour cavité buccale, qui est fixé sur une surface dentaire dure d'une dent. La fixation est réalisée à l'aide d'une quelconque couche adhésive qui peut se fixer sur la surface de l'émail d'une dent ou à l'aide d'un dispositif de retenue fixé à la surface dentaire dure, auquel le dispositif de retenue est attaché, clipsé ou fixé. Le dispositif comprend deux matériaux polymères ou plus formant une ou plusieurs matrices polymères. Les matrices polymères incorporent un ou plusieurs agents, dont le taux de libération dans la cavité buccale peut être contrôlé avec les matériaux polymères dans les matrices. L'invention concerne également un procédé de production d'un dispositif à libération contrôlée pour administrer un agent à la cavité buccale.
