A mucosal adjustment material comprising a combination of a powdery material (a) and a liquid material (b), characterized especially in that a noncrosslinked (meth)acrylic polymer powder having a Tg in the range of 0-60 DEG C, e.g., polybutyl methacrylate, is used as the powdery material and a liquid polymer which has a mass-average molecular weight of 1,000-10,000 and in which the content of oligomers having a molecular weight of 500 or lower is 10 mass% or lower is used as the liquid material. Such powdery material and liquid material are kneaded together to prepare a paste, which is applied to a denture base and used as a temporary relining material. This mucosal adjustment material in a paste form is reduced in the amount of ingredients eluted from the material during use in the mouth. In an ordinary use period, the relining material retains its initial flexibility and does not deteriorate the denture base.
一种由粉末状材料(a)和液体材料(b)组合而成的粘膜调节材料,其特征在于粉末状材料使用 Tg 在 0-60 摄氏度范围内的非交联(
甲基)
丙烯酸聚合物粉末,例如聚
甲基丙烯酸丁酯;液体材料使用质量平均分子量在 1,000-10,000 之间的液体
聚合物,其中分子量在 500 或以下的低聚物含量在 10 质量%或以下。将粉末状材料和液体材料揉捏在一起,制成糊状,涂抹在义齿基托上,用作临时衬垫材料。这种糊状的粘膜调整材料在口腔中使用时,材料中的洗
脱成分会减少。在正常使用期间,衬垫材料保持其最初的柔韧性,不会损坏义齿基托。
