Claim:
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; wherein said retention device is one of: substantially biodegradable, self-degradable, substantially resorbable and substantially non-resorbable, and further comprising stiffening elements embedded in the matrix material; wherein said stiffening elements comprise a plurality of fibers; wherein each said precursor portion is foldable about a fold line to thereby provide said retention device; and wherein said fibers are arranged such as not to cross said fold line.
