Patients are becoming more and more aware of the esthetic alternatives to dental amalgam and are asking dentists to offer solutions that are more esthetically pleasing. However, the difficulties in inserting clinically durable composite resin restorations in the posterior area are numerous. With the high-copper amalgam systems, the dental profession has had an excellent restorative material. In the past there have been attempts to combine amalgam with the esthetic qualities of composite resin. The introduction of an adhesive and opaque light-curing glass-ionomer liner has created new opportunities to bond composite resin to existing amalgam restorations on esthetically disturbing surfaces. This paper describes a simple and quick way in which unesthetic buccal and occlusal extensions of amalgam restorations can be veneered with composite resin. Preliminary six-month results of about 100 restorations are presented. This method may prevent the premature replacement of good functioning amalgam restorations with porcelain-fused-to-metal crowns or composite resin restorations for only esthetic reasons.
患者越来越意识到除牙科汞合金之外的美学替代方案，并要求牙医提供更美观的解决方案。然而，在后牙区域植入临床耐用的复合树脂修复体存在诸多困难。有了高铜汞合金系统，牙科行业拥有了一种出色的修复材料。过去曾尝试将汞合金与复合树脂的美学特性相结合。一种粘结性和不透明的光固化玻璃离子衬层的引入，为在美学上令人困扰的表面将复合树脂粘结到现有的汞合金修复体上创造了新机会。本文描述了一种简单快捷的方法，通过该方法可以用复合树脂为汞合金修复体不美观的颊侧和咬合面延伸部分制作贴面。展示了约100个修复体的初步六个月结果。这种方法可能会防止仅出于美学原因而用烤瓷熔附金属冠或复合树脂修复体过早替换功能良好的汞合金修复体。
