The porcelain-fused-to-metal restoration is and will remain one of the most common restorations in dentistry. However, with the many variables that exist in fabrication and function of these restorations, there also is a potential for failure. This failure usually involves the porcelain portion of the restoration. A simple and predictable technique is extremely advantageous in prolonging the longevity of these restorations. A combination of metal preparation along with specific porcelain treatment will result in such a repair. The specific porcelain treatment involves a combination of hydrofluoric acid etching and a saline bonding agent. The technique has been used for numerous repairs with excellent success.
烤瓷熔附金属修复体过去是、现在仍然是牙科领域最常见的修复体之一。然而,由于这些修复体在制作和功能方面存在诸多变量,因此也存在失败的可能性。这种失败通常涉及修复体的瓷部分。一种简单且可预测的技术对于延长这些修复体的使用寿命极为有利。金属预备与特定的瓷处理相结合将实现这种修复。特定的瓷处理包括氢氟酸蚀刻和一种盐类粘结剂的联合使用。该技术已用于大量修复,取得了极佳的效果。
