CGF-1型复合体的物理机械性能

The physico-mechanical properties of CGF-1 type compomer

目的：评价研制的新型光固化复合体ＣＧＦ－１与Ｄｙｒａｃｔ复合体、ＣＯ－１和ＦＵＪＩⅡ玻璃离子水门汀的物理机械性能。方法：按照有关实验方法分别测试研制复合体与对照材料的压缩强度、径向拉伸强度、挠曲强度、表面硬度。结果：ＣＧＦ－１的ＣＳ、ＤＴＳ、ＦＳ值都明显高于ＣＯ－１、ＦＵＪＩⅡ，接近Ｄｙｒａｃｔ。结论：ＣＧＦ－１型复合体的机械强度明显高于玻璃离子。

Aim: To evaluate the physico-mechanical properties of CGF-1, Dyract compomers and CO-1, FUJI Ⅱ glass ionomer cements. Methods:The compressive strength(CS), diametral tensile strength(DTS), flexural strength(FS)and surface hardness(Hv) of those materials were measured in accordance with relevant test methods. Results: The CS, DTS, FS of CGF-1 type compomer were stronger than those of CO-1type, FUJI Ⅱtype glass ionomer cements, close similar to those of Dyract compomer. Conclusions: The mechanical strength of CGF-1 type compomer were significantly higher than that of CO-1 and FUJI Ⅱ. It may be used as a dental filling restorative material.
