市販軟質裏装材10種類の物理・機械的性質と臨床的観察

Ten commercial soft lining materials were selected to be representative of the types currently available including plasticised acrylic, silicone and fluorine-containing materials. These have been investigated in terms of their tensile, tear and hardness properties. With the exception of tear strength, where silicone materials had the lowest values, there appeared to be no correlation between material type and property. All but two of the materials had hardness values in the range of 30.3 to 43.7. The general conclusion was that the materials selected showed a large variability in the properties investigated. Regarding clinical aspects of some soft lining materials used for acrylic resin denture bases, it was appeared that colour change and deterioration occurred
