Proper dowel pin placement in the working cast is important in the fabrication of a cast restoration. A technique is suggested whereby the dowel pin is orientated and cemented after the working cast has been separated from the impression. This procedure produces a working die that has a correctly positioned dowel pin, is stable, and can be repeatedly returned to its original relationship.

在铸造修复体的制作中，在工作模型上正确放置桩钉很重要。建议采用一种技术，即在工作模型与印模分离后，对桩钉进行定向和粘结。该方法可制作出一个工作模型，其桩钉位置正确、稳定，且能反复恢复到其原始关系。建议采用一种技术，即在工作模型与印模分离后，对桩钉进行定向和粘结。该方法可制作出一个工作模型，其桩钉位置正确、稳定，且能反复恢复到其原始关系。
