A technique has been developed whereby collarless metal-ceramic crowns can be fabricated by spot-welding the platinum-foil matrix to the casting after it has been contoured for porcelain application. The main advantage of this procedure over previously reported techniques is that it produces well fitted restorations while requiring a lesser degree of technical skill.
已开发出一种技术，通过该技术可以在铸造体已为应用瓷进行塑形后，将铂箔基体点焊到铸造体上，从而制作无颈缘金属烤瓷冠。与先前报道的技术相比，该方法的主要优点是，它能制作出贴合良好的修复体，同时所需的技术技巧程度较低。
