Three techniques have been described which may be used to repair many porcelain-fused-to-metal restorations. These techniques provide an avenue of repair for extensive porcelain-fused-to-metal restorations without remaking the entire prosthesis. The success of the overlay and pin-retained ceramo-metal repairs should be comparable to that of a newly constructed porcelain-fused-to-metal restoration. The composite resin bonded to porcelain repair technique will not have as favorable a prognosis, as composite resins are more subject to wear and are not color stable, and the chemical bond created with silance bonding agents is much weaker than the bond created when porcelain is fused to metal. Success of silance-bonded repairs should not be expected for periods longer than 2 to 3 years.
已经描述了三种可用于修复许多烤瓷熔附金属修复体的技术。这些技术为广泛的烤瓷熔附金属修复体提供了一种无需重新制作整个修复体的修复途径。覆盖层和针固式烤瓷熔附金属修复的成功率应与新制作的烤瓷熔附金属修复体相当。粘结到烤瓷上的复合树脂修复技术的预后不会那么好，因为复合树脂更容易磨损且颜色不稳定，并且与硅烷粘结剂形成的化学键比烤瓷熔附到金属上时形成的键弱得多。对于超过2至3年的时间，不应期望硅烷粘结修复能成功。
