摘　　要：目的:研究纳米/微米SiO_2混合填料对新型牙科复合树脂机械性能的影响。方法:将纳米/微米SiO_2混合填料加入联苯基单体TMBPEA中,制备新型牙科复合树脂。实验分为5个实验组和1个以Bis-GMA为单体的对照组,测试各组试样的挠曲强度、弹性模量;扫描电镜观察含SiO_2填料样本的断面形貌。结果:含TMBPEA和50%SiO_2填料组试样的机械性能最高,挠曲强度和弹性模量分别为(96.83±0.55)MPa、(7.12±0.20)GPa。SEM结果显示该组试样的无机填料均匀致密地分散在连续的有机基质中。结论:以TMBPEA为基质的复合树脂是一种有应用前景的牙科复合树脂材料。Objective:To evaluate the effect of nanometer/micron SiO 2 mixed filler on mechanical properties of a new type of dental composite resin.Methods:A new type of dental composite resin was prepared by adding nanometer/micron SiO 2 mixed packing to monomer of TMBPEA.The experiment was divided into five experimental groups and one control group with Bis-GMA as the monomer,and the flexural strength and elastic modulus of each group were tested.The section morphology of samples containing SiO 2 fillers were observed by SEM.Results:The mechanical properties of the samples with TMBPEA and 50%SiO 2 filler were the highest.Its bending strength and elastic modulus were(96.83+0.55)MPa and(7.12±0.20)GPa,respectively.SEM results showed that the inorganic filler of the sample was dispersed uniformly in the continuous organic matrix.Conclusion:The composite resin with TMBPEA as matrix has promising application prospect.
