摘要/Abstract

摘要： 目的：比较4种光固化复合树脂对种植义齿固定螺丝孔的封闭效果，观察有机硅烷偶联剂对固定螺丝孔微渗漏的影响，分析冷热循环试验对固定螺丝孔微渗漏的影响。方法：制备80个钛合金中空半圆柱状试件(上1/2表面烤瓷，内表面喷砂+酸蚀处理)，分为偶联剂和非偶联剂组，分别用4种光固化树脂进行封闭，各组再作对比冷热循环试验。用葡萄糖氧化酶-过氧化物酶法(GOD-POD)测量微渗漏情况,采用SAS 11.10软件包对数据进行方差分析。结果：4种光固化复合树脂间、偶联剂组与非偶联剂组间、冷热循环组与对照组间微渗漏均有显著差异(P<0.01)。在对封闭材料(A因素)、偶联剂处理(B因素)、冷热循环试验(C因素)三因素的交互作用分析中发现，只有B因素与C因素间具有交互作用(P<0.01)；AB间、AC间、ABC间则均无交互作用(P>0.05)。结论：封闭材料是影响固定螺丝孔微渗漏的一个重要因素。使用偶联剂可有效减少黏结界面的微渗漏，实验试件对冷热循环试验的耐受性差。

Abstract: PURPOSE: The purpose of this study was to evaluate closure of the fixation screw pores of implant denture by using 4 different light-cured composite resins (LCRs), and to observe the effects of organosilane and thermocycling on microleakage. METHODS: A total of 80 hollow semi-cylinders were fabricated with titanic alloy, with the upper half of the specimens was porcelain, and the internal surfaces were sandblasted and etched. All specimens were divided into 2 groups: treated and not treated with organosilane. After bonding with 4 kinds of LCRs, the testing samples were assigned into 2 subgroups for different thermocycles. Then the degree of microleakage were measured by glucose oxidase-peroxidase(GOD-POD) methods. The results were statistically analyzed with one-way ANOVA by using SAS 11.10 software. RESULTS: Statistical analysis revealed that the microleakage associated with LCRs were significantly different, and the microleakage associated with organosilane or thermocycles were also significantly different (P<0.01). Interactive analysis showed that there was interaction between the organosilane disposal (factor B) and thermocycling disposal (factor C) (P<0.01), whereas no interaction was found between the other factors (P>0.05). CONCLUSIONS: The results suggest that the type of bonding materials would affect the degree of microleakage, and the microleakage can be reduced if the specimens are treated with organosilane. The tolerance of specimens under thermocycling are very poor.
