摘要
目的：观察玻璃离子水门汀（ＧＩＣ）中直接加入不同比例银合金粉后的机械性能。方法：测试实验材料的抗压强度和表面硬度。结果：加入银合金粉后ＧＩＣ抗压强度和表面硬度明显下降，并且加入量越大，下降越明显。结论：ＧＩＣ中直接加入银合金粉不能改善ＧＩＣ的机械性能。
Aim: The mechanical properties of GIC admixed directly with dentalamalgam alloy particles of different ratio were investigated. Methods: The compressive strength and surface hardness of the admixed GIC were examined. Results: The compressive strength and sarface hardness of the admixed GIC were significantly lower than those of GIC itself. The more the metallic particles were incorporated with, the lower the compressive strength and surface hardness of admixed GIC were. Conclusions: GIC admixed directly with dental amalgam alloy particles couldn't improve the mechanical properties of GIC.
