DEVICE FOR FIXATION AT A DENTAL SITE

摘要

A reshapable retention device for insertion at a dental site and contact with adjacent dental surfaces, for the controlled delivery to the dental site of at least one material having a predetermined intraoral activity. The retention device comprises at least one matrix containing the material. The retention device is adapted for physically affixing at the dental site for at least a predetermined time period correlated to the delivery of a predetermined portion of the at least one matrix to the dental site in a controlled single, bi or multiphase pattern. The retention device comprises a first configuration in which the overall dimensions of the retention device are larger than at least one dimension of the dental site. The first configuration is reshapable to a second configuration in which at least one dimension of the retention device is reduced to enable physically affixing the retention device at the dental site. In the second configuration the retention device comprises a predetermined shape having contours for affixing at the dental surfaces.

主权项

1. A substrate having a substrate width dimension, a substrate length dimension and a substrate thickness dimension, the substrate made from a polymeric matrix material and capable of containing at least one active material having a predetermined intraoral activity or at least one inactive material, wherein at least one of said substrate width dimension or said substrate length dimension is sufficiently large to enable at least two precursor portions of the substrate to be separated from the substrate, each precursor portion being manipulable to enable altering at least one of the shape and size of the precursor portion to thereby provide a retention device that is configured for being retained at a dental site and for delivering the active material or inactive material to a dental site, said substrate further comprising a plurality of separating facilitators defining separation boundaries between said precursor portions and configured for facilitating separation of respective said precursor portions from a remainder of said substrate.
