An oral care agent delivery device is provided which comprises a permanently deformable backing layer (170), an anchor layer (180) overtop the backing layer, and an oral care layer (190) overtop the anchor layer. The device is sized to fit over a plurality of teeth in an upper or lower dental arch of a subject. The oral care layer (190) comprises at least one oral care agent and at least one hydrophilic polymer. The oral care layer is in contact with the anchor layer and forms an adhesive bond with the anchor layer; however, the oral care layer is minimally invested in the anchoring layer. When hydrated, the oral care layer has an adhesiveness relative to the surface of a user's teeth that is sufficient to retain the device on the user's teeth when placed thereon. The device can also have an oral care agent which is activated on hydration of the oral care layer, or an oral care layer which releases the oral care agent over time.
提供了一种口腔护理剂输送装置,它包括一个可永久变形的背衬层(170)、一个覆盖在背衬层上的锚层(180)和一个覆盖在锚层上的口腔护理层(190)。该装置的尺寸适合套在受试者上牙弓或下牙弓的多颗牙齿上。口腔护理层 (190) 包括至少一种口腔护理剂和至少一种亲水性聚合物。口腔护理层与锚定层接触,并与锚定层形成粘合;然而,口腔护理层在锚定层中的投入极少。水合时,口腔护理层相对于使用者牙齿表面的粘附力足以将装置固定在使用者的牙齿上。该装置还可以有一种口腔护理剂,在口腔护理层水合时被激活,或者口腔护理层随着时间的推移释放口腔护理剂。
