Class II Adhesive Restorations have been realized with composites under laboratory conditions. They show a perfect marginal adaptation and no microleakage at the tooth/restoration interface. These properties were obtained a) with a new cavity preparation, b) by application of a low viscosity sealant prior to the placement of the bulk of the composite material. The Adhesive Restoration compared favorably with conventionally prepared restorations. Nevertheless, enamel conditioning with acid and the use of a low viscosity sealant in conventionally prepared class II cavities resulted also in some improvement of marginal adaptation.
II类粘结修复体已在实验室条件下用复合材料实现。它们在牙齿/修复体界面显示出完美的边缘适应性且无微渗漏。这些特性是通过以下方式获得的：a）采用一种新的窝洞制备方法；b）在放置大部分复合材料之前先应用低粘度封闭剂。与传统制备的修复体相比，粘结修复体表现良好。然而，在传统制备的II类窝洞中用酸处理牙釉质并使用低粘度封闭剂也能在一定程度上改善边缘适应性。
