Four materials: amalgam, Epoxydent, Adaptic and concise Cap were filled after certain criteria into class II mandibular cavities and examined after one year. The very accurate models were submitted to measuring with a three-dimensional measuring device. The results were the following: amalgam 18 +/- 58 micron Epoxydent 38 +/- 50 micron Adaptic 92 +/- 97 micron Concise Cap 146 +/- 75 micron Only the first difference between amalgam and Epoxydent is statistically insignificant, the others are all relevant. Furthermore, a mean abrasion of functional cusps of 70 micron and a maximum abrasion of 300 micron could be observed. Clinically, relative to marginal adaptation and discoloration, Adaptic was clearly superior to the other two composites. Class II cavities must routinely be restored with amalgam, and composite "streets" must be strictly avoided.
汞合金、Epoxydent、Adaptic和简明帽按照一定标准填充到下颌II类洞型中，一年后进行检查。用三维测量装置对非常精确的模型进行测量。结果如下：汞合金18±58微米，Epoxydent 38±50微米，Adaptic 92±97微米，简明帽146±75微米。只有汞合金和Epoxydent之间的第一个差异在统计学上不显著，其他差异均具有相关性。此外，可观察到功能尖的平均磨损为70微米，最大磨损为300微米。临床上，相对于边缘适应性和变色，Adaptic明显优于其他两种复合材料。下颌II类洞型必须常规用汞合金修复，并且必须严格避免使用复合树脂。
