66 composite filings of the brands Classecond, Epoxydent and Compocap were examined for marginal fit. The two first brands can be carved, the latter cannot. The fillings were examined by vacuum color diffusion tests, and replicas of the fillings were viewed with the EM. 91% of the Compocap fillings were found to be color impermeable, while 64% of the Epoxydent and 55% of the Classecond fillings proved to be leaking at the margins. The EM examination showed that carving the fillings causes considerably more leakage and short margins. For this reasons, it is unadvisable to carve even the carvable composits. The use of such materials then of course becomes questionable.
对Classecond、Epoxydent和Compocap品牌的66颗复合填充物进行了边缘适合性检查。前两个品牌的填充物可以雕刻,而后者则不行。通过真空颜色扩散测试对填充物进行检查,并使用电子显微镜观察填充物的复制品。结果发现,91%的Compocap填充物是颜色不可渗透的,而64%的Epoxydent填充物和55%的Classecond填充物在边缘处被证明有渗漏。电子显微镜检查表明,雕刻填充物会导致更多的渗漏和短边缘。因此,即使是可雕刻的复合材料也不建议雕刻。那么使用这类材料当然就成问题了。
