近年来，贱金属合金在牙科中的使用得到了广泛的普及。然而，关于其安全性的声明并没有被普遍接受。一个人工口腔环境能够再现三维forcemovement周期的人类咀嚼被用来确定是否镍，铬，铍离子从基础金属合金浸出。12对牙冠以以下组合进行连接：金属与金属，金属与釉质，金属与瓷，金属与金属不咀嚼作为对照。在模拟1年的咀嚼期间，结果表明，镍和铍金属释放的溶解和咬合磨损。这些发现表明，如果这些情况发生在口腔中，基础金属合金的稳定性受到质疑。需要进一步的研究来确定所报告的浸出是否对接受贱金属置换的患者具有长期后果。
The use of base metal alloys in dentistry has gained wide popularity in recent years. However, claims of their safety have not been universally accepted. An artificial oral environment capable of reproducing three-dimensional forcemovement cycles of human mastication was used to determine whether nickel, chromium, and beryllium ions were leached from base metal alloy. Twelve pairs of crowns were articulated in the following combinations: metal versus metal, metal versus enamel, metal versus porcelain, and metal versus metal without chewing as a control. In a simulated 1-year period of mastication, the results showed that nickel and beryllium metals were released both by dissolution and occlusal wear. These findings suggest that if these conditions occur in the oral cavity, the stability of base-metal alloys is subject to question. Further studies are needed to determine whether the leaching reported has long-term consequences for patients receiving base metal restorations.
