In 41 patients class 11 cavities each of the lower jaw were filled with the materials Adaptic, Concise cap, Epoxydent or amalgam. The models made from impressions were systemically measured by a coordinate measuring machine according to a procedure determined by us (measuring error of this method about 15 micron). After one year the following abrasions were found: amalgam 18 micron +/- 58 micron, Adaptic 92 micron +/- 97 micron, Concise Cap 146 micron +/- 75 micron, Epoxydent 38 micron +/- 50 micron. Evaluation of the clinical examination showed that the materials Concise and Epoxydent were significantly inferior as regards border closure than amalgam and Adaptic. We determined further that a large percentage of composite filling showed visible discoloration of the borders (Adaptic 42%, Concise 55%, Epoxydent 80%). Many of the fillings were discolored after a year. Adaptic was highly significantly different with 31.6% discolored fillings to both other materials (Concise 79%, Epoxydent 78.4%).
在41例下颌Ⅱ类洞患者中，分别用Adaptic、Concise cap、Epoxydent或银汞合金材料进行充填。根据我们确定的程序，用坐标测量仪对由印模制成的模型进行系统测量（该方法的测量误差约为15微米）。一年后发现以下磨损情况：银汞合金18微米±58微米，Adaptic 92微米±97微米，Concise Cap 146微米±75微米，Epoxydent 38微米±50微米。临床检查评估显示，在边缘封闭方面，Concise和Epoxydent材料明显不如银汞合金和Adaptic。我们进一步确定，很大比例的复合充填物边缘出现可见变色（Adaptic为42%，Concise为55%，Epoxydent为80%）。许多充填物在一年后变色。Adaptic与其他两种材料相比，变色充填物比例差异极显著（Concise为79%，Epoxydent为78.4%，而Adaptic为31.6%）。
