ABSTRACT:
A new dental adhesive device to hold and cushion prosthetic devices in the human mouth is made as a laminate of webs which are bonded together by thermoplastic ethylene oxide polymer. The dental adhesive exemplified is produced by continuously applying thermoplastic ethylene oxide polymer between moving webs of cellulose acetate fibers, and thence passing said webs in superimposed relationship between a pair of dry heated calendar rolls for thermoplastically bonding said web into a unitary structure. A dry water-activated adhesive material such as sodium alginate may be admixed with the thermoplastic ethylene oxide polymer and applied to the moving webs before passing between the calendar rolls. It is also contemplated that the synthetic fibers be applied to the webs so as to extend transversely through the webs with the free ends of the fibers from each web being entangled so as to be mechanically interlocked. A further embodiment for a thinner dental cushion is also disclosed, wherein instead of a web laminate, a thin paper laminate is utilized with ethylene oxide polymer extruded as a thin sheet as the bonding agent.
