PURPOSE:A repairing material of dental polysulfone resin, capable of carrying out simply rebase and relining of polysulfone artificial dentition, showing im proved properties, obtained by using an unsaturated polyester as a repairing material. CONSTITUTION:An nunsaturated polyester of cold-polymerization type or heat- polymerization type is used as a repairing material for rebase and relining of polysulfone artificial dentition. An unsaturated polyester resin of maleic anhydride type or furmaric acid type is used as the unsaturated polyester. An oxide such as benzoyl peroxide, methyl ethyl ketone peroxide, cyclohexanone peroxide, etc., are used as a polymerization initiator and cobalt naphthenate is added when the cold-polymerization is carried out.
