Abstract
Disclosed is a method for producing an intra-oral dental bandage membrane and/or therapeutic membrane containing therapeutic agent. Actinic light is used to polymerize the membrane composition material to fix the composition in position locked with rigid dental structure such as teeth. The polymerizable substance is manipulated and shaped in a fluid state and then set, as shaped very rapidly in situ. Also disclosed is a new treatment membrane that in a preferred form is a non-symetrical oligomer that is a urethane polyacrylate.
