摘要

采用海藻酸盐、锡纸和硅胶等不同的分离方法，研究了热聚合义齿基材(聚甲基丙烯酸甲酯)和冷聚合义齿基材的材料性能。无论是锡箔和硅胶隔离处理，这是更容易导致孔隙率的减少部分和增加的显微硬度在PMMA。

[The porosity, microhardness, roughness and internal stresses of PMMA base materials in relation to their isolation. 1. Porosity and microhardness].

Selected material properties of hot and cold polymerized denture basic materials (polymethylmethacrylate) were investigated after different methods of isolation: alginate, tin foil and silicone. Both tin foil and silicone isolation the handling of which is much easier result in a decreased portion of porosities and an increased microhardness in the PMMA.
