an improved dental adhesive device to hold prosthetic devices in the human mouth is made as a laminate of webs which are bonded together by deforming a film of thermoplastic ethylene oxide polymer . the dental adhesive is produced by continuously applying a film of thermoplastic ethylene oxide polymer between moving webs of cellulose acetate fibers and then passing said webs in superimposed relationship between a pair of dry heated calendar rolls for thermoplastically bonding said webs into a unitary structure . a dry water - activated adhesive material , such as sodium alginate , may be employed with the thermoplastic ethylene oxide polymer by being dissolved or dispersed in the polymer film . synthetic fibers are applied to the webs so as to extend transversely through the webs .
