探讨不同成分对义齿粘接剂与基托的初始黏度及粘接强度的影响。采用了两种水溶性聚合物（甲氧基乙烯马来酸酐共聚物[PVM-MA]和羧甲基纤维素钠[CMC]）。样本被分为三组。组1仅含PVM-MA；第二组仅含CMC；第3组含有PVM-MA和CIVIC。测定了初始粘度和粘接强度。对于第1组，随着PVM-MA含量的增加，初始粘度显著增加。1组的粘接时间较2组长。第3组的粘接强度变化较大。CMC与PVM-MA的配比对义齿粘接剂的初始粘度和粘接强度有显著影响。我们的研究结果表明，通过结合不同的水溶性聚合物来提高义齿粘接剂的耐久性是可能的。
To investigate the effect of composition on the initial viscosity and adhesive strength between denture adhesives and the denture base. Two types of water-soluble polymers (methoxy ethylene maleic anhydride copolymer [PVM-MA] and sodium carboxymethyl cellulose [CMC]) were used. Samples were divided into three groups. Group 1 contained only PVM-MA; Group 2 contained only CMC; and Group 3 contained PVM-MA and CIVIC. The initial viscosity and adhesive strength were measured. For Group 1, the initial viscosity increased significantly as PVM-MA content increased. The adhesive strength of Group 1 lasted longer than Group 2. The adhesive strength of Group 3 varied greatly. The ratio of CMC and PVM-MA has a significant effect on the initial viscosity and adhesive strength of denture adhesives. Our results suggest that it is possible to improve the durability of a denture adhesive by combining different water-soluble polymers.
