To remove a toxic substance before or after it is absorbed into a body with a simple means without damaging the body by forming a denture base pack material with a material having the function to adsorb or absorb toxic substances having a toxic action for an organism.
A coarse material is used rather than a dense material for the base raw material of a denture base pack material to adsorb or absorb toxic substances and bacteria in a mouth cavity or to easily diffuse the toxic substances. A polymer which is a well-known material used as a covering composition such as a paint in the past, resolved in an organic solvent for use, or capable of being used as an aqueous emulsion is used. Polybutadiene, polyisoprene, polyvinyl chloride, or polyvinylidene chloride is used for this polymer. Silica gel, alumina, aluminum hydroxide, or titania is used for an adsorbent or a reactive material capable of being blended with the denture base pack material.
