ABSTRACT:
Combining nanosized particles of a source of desired dental restorative, repair or therapeutic materials with strengthening agents in various generally nanosized form such as whiskers, fibers, particles and the like in a resin matrix provides a highly strain resistant composite which more effectively releases the therapeutic agents. The utilization of nano sized particles of the therapeutic agent in the combination enables observation of significantly improved therapeutic results.
