ABSTRACT:
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.
