摘要： 目的:研究纳米/微米SiO2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SiO2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SiO2填料样本的断面形貌。结果:含TMBPEA和50%SiO2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。

Abstract: Objective: To evaluate the effect of nanometer/micron SiO2 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 SiO2 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 SiO2 fillers were observed by SEM. Results: The mechanical properties of the samples with TMBPEA and 50% SiO2 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.
