A denture temporary relining material composition is disclosed, including (A) 100 parts by weight of an organopolysiloxane containing at least two alkenyl groups in one molecule and having a viscosity of from 0.5 to 20 Pa.s at 25&deg; C.; (B) from 0.1 to 40 parts by weight of an organohydrogen polysiloxane containing at least three hydrogen atoms directly bonded to a silicon atom in one molecule; (C) from 10 to 500 ppm, based on the total amount of the components (A) and (B), of a silicone-soluble platinum compound; (D) from 10 to 200 parts by weight of an inorganic filler; (E) from 0.5 to 100 parts by weight of an organopolysiloxane raw rubber containing at least two alkenyl groups in one molecule and having a viscosity of from 1,000 to 20,000 Pa.s at 25&deg; C.; and (F) from 1 to 200 parts by weight of a methylphenyl polysiloxane which is very low in terms of the hardness of a set product, keeps a softness in the oral cavity for a long period of time, does not generate changes in the surface properties, and is not deteriorated even upon immersing in a denture cleanser solution.
