REGULATOR OF ADHESIVENESS BETWEEN MUCOSA REGULATING MATERIAL FOR DENTAL USE AND (METH)ACRYLIC-BASED DENTURE BASE

摘要

PROBLEM TO BE SOLVED: To solve a problem that when a mucosa regulating material for a dental use is applied to a (meth)acrylic denture base, a plasticizer such as a phthalic ester, etc., contained in the mucosa regulating material is migrated to the denture base with time, firmly integrated and is difficult to remove when a mucosa regulating material is renewed.;SOLUTION: An organic solvent solution containing 0.5-30% by mass of a polymer having a monomer unit based on methyl (meth)acrylate and a monomer unit based on a (meth)acrylate of a ≥3C (preferably 3-20C) alcohol is used as an adhesiveness regulation material to be applied to a denture base before application of a mucosa regulating material. Consequently, the integration of a plasticizer is prevented while maintaining a sufficient initial adhesive strength. Preferably a copolymer of methyl (meth)acrylate and polybutyl (meth)acrylate or polyisobutyl (meth)acrylate is used as the polymer and ethyl acetate, acetone, isopropyl alcohol, etc., are used as the organic solvent.;COPYRIGHT: (C)2006,JPO&NCIPI
