自其引入以来，复合树脂填充材料已取代直接填充树脂和硅酸盐水泥作为前牙充填的首选材料，其中美学是首要考虑的。这些材料尽管有一些性能缺点，但已得到广泛接受。据报道，许多市售复合树脂材料在修复体边缘处表现出一定程度的渗漏（1-4）和总表面崩解（5）。许多研究人员试图将这些问题追溯到系统的一些基本性质，如吸水性和聚合收缩（6）。由于这一系统的复杂性，这些调查的结果尚未得出结论。
Since their introduction, composite resin filling materials have replaced direct filling resins and the silicate cements as the materials of choice for anterior restorations where aesthetics are of the primary importance. These materials have met with wide acceptance in spite of several performance shortcomings. It has been reported that many of the commercial composite resin materials exhibit some leakage at the margins of the restoration (1–4) and gross surface disintegration (5). Many investigators have attempted to trace these problems to some basic properties of the system, such as water sorption and polymerization shrinkage (6). Due to the complex nature of this system, the results of these investigations have not been conclusive.
