摘　　要：目的研究低温等离子体表面处理和传统纤维桩表面处理对纤维桩与树脂材料的粘结强度影响,得出有效可行的纤维桩表面处理方法。方法玻璃纤维桩分组,A组无特殊处理;B组经氧气低温等离子体表面处理15 min;C组30%H_2O_2浸泡10 min后硅烷化1 min;D组50μm Al_2O_3喷砂后硅烷化1 min。通过微推出测试、三点弯曲强度检测、扫描电镜观察方法得到处理后纤维桩的粘结强度、三点弯曲强度、纤维桩的表面形态。结果低温等离子体处理组纤维桩与树脂界面的粘结强度最高,纤维桩三点弯曲强度与无处理组比较无显著差异。结论低温等离子体表面处理技术与H_2O_2和喷砂后涂布硅烷偶联剂处理相比粘结强度提升更高,且不影响纤维桩本身的机械性能,可以应用于临床。Objective To study the effect of low temperature plasma surface treatment and traditional fiber post surface treatment on the bonding strength of fiber posts and resin materials, and to obtain an effective and feasible method for surface treatment of fiber posts. Methods Glass fiber post groups： group A had no special treatment; group B was treated with oxygen low temperature plasma surface 15 min ; group C was 30% H2O2 soaked for 10 min and silanized for 1 min; group D was 50 μm A1203 sandblasted and silanized for 1 min. The bond strength, the three point bending strength and the surface morphology of the fiber post were obtained by micro launch test, three point bending strength test and SEM observation. Results The bond strength between fiber post and resin was the highest in the low temperature plasma treatment group. There was no significant difference between the three point bending strength of fiber post and no treatment group. Conclusions The low temperature plasma surface treatment technology increases bond strength more than that of H2O2 and the silane coupling agent after sandblasting, and it has no obvious influence on the mechanical properties of the fiber post.
