| 摘 要： | 目的：探讨不同熔附条件对新型牙科复合树脂弯曲性能的影响。方法：将自制的以硼酸铝晶须（ABw）和二氧化硅（SiO2）为主要成分的新型牙科复合树脂混合填料在不同熔附条件下制作试样并测试其弯曲强度和弯曲弹性模量;利用透射电镜（TEM）观察高温处理过程对晶须表面形态的影响。结果：ABw-SiO2熔附体复合填料可显著提高牙科复合树脂的弯曲性能;高温处理过程并未破坏ABw表面形态;熔附温度和时间为900℃、30 min时新型牙科复合树脂的弯曲强度达（151.90±8.89）MPa。结论：不同熔附条件改善了新型牙科复合树脂的弯曲性能。

| Abstract: | Objective: To evaluate the influence of fusing conditions on the flexural properties of a new type of dental composite resins dealed.Methods: A new type of dental composite resins using ABw-SiO2 compound as inorganic fillers were made.They were sintered under different fusing conditions,and then their flexural strength and Young's modulus were determined.The effects of heat treatment on the surface morphology of ABw were characterized by TEM. Results: The flexural properties of dental composite resins with ... |
