Patient's aesthetic requirements have increased in the past few years. The limited resistance of composites to wear has delayed their universal adoption for restoration of Class I and II cavity preparations in adult teeth. Although the potential use for posterior composite resin appears promising, the point at which such materials may be regarded as ideal, reliable, routine alternatives to silver amalgam has not been reached for materials of previous generation. To resolve some of the problems associated with the posterior composite resin, new materials (photo-cured GIC, multi step bonding agent, improved composite resins as P-50, Heliomolar Radiopaque, Ray Post) and new techniques have been introduced. In this paper the problems and questions raised with the use of posterior composites have been discussed.
在过去几年中，患者的美学需求有所增加。复合材料耐磨性有限，这延缓了它们在成人恒牙Ⅰ类和Ⅱ类洞修复中的广泛应用。尽管后牙复合树脂的潜在用途看起来很有前景，但对于上一代材料而言，尚未达到可将其视为银汞合金的理想、可靠、常规替代品的程度。为了解决与后牙复合树脂相关的一些问题，已引入了新材料（光固化玻璃离子水门汀、多步粘结剂、改良复合树脂如P-50、含放射阻射剂的Heliomolar复合树脂、Ray桩核）和新技术。本文讨论了使用后牙复合材料时出现的问题。
