<P>PROBLEM TO BE SOLVED: To provide a mucous membrane conditioning material by kneading a powder material and a liquid material, with high operability and handling immediately after kneading, and capability in forming a sufficiently thick layer on the mucous membrane of a denture base, and maintaining the thickness for a long period, and further with high tearing strength, so that it can be used for a long period of time. <P>SOLUTION: The mucous membrane conditioning material layer with a sufficient thickness can be formed by blending a porous organic crosslinking polymer with a (meth)acrylic non-crosslinking polymer particles and a plasticizer, thereby suppressing initial viscosity of the mucous membrane conditioning material resulting in the elevation of operability and a handling property immediately after kneading, and moderately increasing the viscosity of the mucous membrane conditioning material after serving on an artificial tooth. Furthermore, the high tearing strength is developed and the thickness is maintained over long period because the polymer component and the plasticizer component in the mucous membrane conditioning material are permeated and kept in the fine pores of the porous organic crosslinking polymer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
