    • A system for delivering a tooth whitening substance to a plurality of adjacent teeth, the delivery system comprising a strip of flexible material having a sufficient flexibility to form a curved shape on a plurality of adjacent teeth and a tooth whitening substance. The strip of material is readily conformable to the teeth surfaces and to interstitial tooth spaces without permanent deformation when the delivery system is placed thereagainst. The tooth whitening substance is applied to the strip of material such that when the delivery system is placed on the surface of the teeth, the substance contacts the surface providing an active onto the surface. The substance also provides adhesive attachment between the strip of material and the surface to hold the delivery system in place for a sufficient amount of time to allow the active to act upon the surface. The method of delivery includes pre-coating the strip of material or having the wearer apply substance to the strip of material and then applying the delivery system to the teeth surfaces.
    • 一种用于将牙齿美白物质递送到多个相邻牙齿的系统,所述递送系统包括柔性材料条,其具有足够的柔性以在多个相邻牙齿上形成弯曲形状和牙齿增白物质。 当输送系统放置在其上时,材料条很容易符合齿表面和间隙齿隙,而不会永久变形。 将牙齿美白物质施加到材料条上,使得当将递送系统放置在牙齿的表面上时,物质接触表面,从而在表面上提供活性物质。 该物质还在材料条和表面之间提供粘合剂附着,以将输送系统保持在适当位置足够的时间以允许活性物质作用在表面上。 递送方法包括将材料条带预先涂覆或将穿戴者施用物质预先涂覆到材料条上,然后将递送系统施加到牙齿表面。
