Abstract: To provide an adhesive composition for an alginate impression material having excellent adhesive property to materials of various kinds of impression tray such as metal, plastic and the like, and having an effect to a paste type alginate impression material which does not conventionally have sufficient holding force to an impression tray, an adhesive composition for an alginate impression material, has the feature that 1-50 weight % of one or more kinds of compound selected from rosin, ester gum and polyamide resin are dissolved in an organic solvent, where isopropyl alcohol, ethyl acetate, toluene and the like can be used as the organic solvent, and the organic solvent obtained by combining isopropyl alcohol and ethyl acetate or isopropyl alcohol and toluene is preferable, although those can be independently used.

Abstract: To provide a dental alginate impression material composition without the defects of the conventional alginate impression material compositions using a pH indicator, that the confirmation of the completion of the gelation is inaccurate and difficult, and that they are poor in the affinity with water to be used during the mixing, the dental alginate impression material composition containing an alginate, a gelling reaction material, a gelling adjustment material, and a filler as major components further contains 0.001 to 0.1% by weight of one or more pH indicators selected from Cresol Red, &agr;-naphtholphthalein, Tropaeolin OOO, Thymol Blue, and phenolphthalein; 0.1 to 10% by weight of a water-soluble polyether that is a liquid at 25 ° C.; and 0.001 to 5% by weight of an inorganic pigment and/or an organic pigment having a color distinctly different from a color tone caused by color formation of the pH indicator during the gelation upon mixing with water.

Abstract: 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° 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° C.

Abstract: A marginal treatment material of a denture base, comprising (A) 100 parts by weight of an organopolysiloxane having at least two aliphatic unsaturated hydrocarbons in one molecule and having a viscosity of 500˜5,000 cs at 25° C.; (B) 0.5˜30 parts by weight of an organohydrogen polysiloxane having at least three hydrogen atoms directly bonded to a silicon atom in one molecule; (C) 10˜500 ppm, based on the total of the components (A) and (B), of a silicone-soluble platinum compound; and (D) 0.5˜20 parts by weight of fine silica powder having a BET specific surface area of 50˜500 m2/g, whose surface is made hydrophobic.

Abstract: A silicone composition for oral mucosa impression is disclosed, comprising: (A) 100 parts by weight of an organopolysiloxane having at least two aliphatic unsaturated hydrocarbons in one molecule and having a viscosity at 25° C. of 500˜1,500 cS; (B) from 0.1 to 20 parts by weight of an organohydrogen polysiloxane having 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 1 to 20 parts by weight of a linear methylphenyl polysiloxane having a viscosity at 25° C. of 30 to 10,000 cS; (E) from 10 to 200 parts by weight of an inorganic filler; and (F) from 0.5 to 5 parts by weight of one or two or more surfactants selected from nonionic surfactants.
