Undoubtedly the greatest resistance of clinicians to use composite resins in posterior teeth relates to technique sensitivity, time consumption, and complexity. Placing conventional posterior composite resins does not take into account that composites differ considerably from amalgam. This is particularly true with respect to its physical characteristics, especially insertion and packing properties. The development of a posterior composite resin that can be placed by an amalgam carrier and subsequently packed or condensed as an amalgam, should assist clinicians greatly in their ability to successfully restore class II cavity preparations. Acknowledgment is expressed to Bruce Small, DMD, for the clinical dentistry and slides.
毫无疑问，临床医生在使用复合树脂修复后牙时最大的阻力在于技术敏感性、耗时和复杂性。使用传统的后牙复合树脂时，没有考虑到复合材料与汞合金有很大不同。在其物理特性方面，尤其是插入和填充性能方面，情况更是如此。开发一种可以用汞合金输送器放置、随后像汞合金一样进行填充或压实的后牙复合树脂，将极大地帮助临床医生成功修复Ⅱ类洞型。感谢布鲁斯·斯莫尔博士提供临床牙科病例和幻灯片。
