摘要
目的 探讨不同固化方法处理后对复合树脂抗压强度的影响。方法 采用光固化、光固化 +光固化、光固化 +热固化 ,3种不同固化方法处理 3M和贺利氏复合树脂 ,在万能验试机上测试抗压强度。结果 2次处理的复合树脂抗压强度均比 1次处理的复合树脂有较大提高 ,范围在 5 1.8%～ 91.6 %之间。不同的 2次固化方法相比 ,统计学无显著差异。结论 复合树脂经 2次固化方法处理 ,其抗压强度高于 1次光固化方法的处理。
Objective To investigate the effect of composite resins dealed with different curing methods on compressive strength. Methods The compressive strength change were determined by dealing with 3M composite resins and Herues composite resins by light cured, light cured + light cured and light cured + heat cured. Results The compressive strength with secondary cure was significantly higher than that of control groups (light cured only),a range from 51.8%～91.6% ( P <0.05) , but there were no statistical difference between two secondary cure groups. Conclusion The compressive strength of secondary cured composite resins is higher than that of light cured only.
