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，可用作直接充填修复材料
Objective: To evaluate the physical and mechanical properties of CGF-1 and Dyract composite, CO-1 and FUJIⅡ glass ionomer cement. Methods: Compressive strength, radial tensile strength, flexural strength and surface hardness of the developed composite and control materials were respectively tested according to the relevant experimental methods. Results: The values of CS, DTS and FS of CGF-1 were significantly higher than those of CO-1 and FUJIⅡ, and close to that of Dyract. Conclusion: The mechanical strength of CGF-1 complex is obviously higher than that of glass ion, which can be used as direct filling and repairing material
