Fracture or carious lesions in an abutment tooth may require the fabrication of a crown under an existing removable partial denture. Typically, once the crown has been fabricated, the prosthesis will need to be modified or refabricated. However, if the partial denture is in good clinical condition, special techniques may be applied to make the new crown fit the existing prosthesis. This article describes a straightforward indirect-direct technique for fabricating a cast metal crown under an existing removable partial denture with hot water. The technique does not require expertise or any special device and can be performed chairside by general dentists.
基牙的折裂或龋坏可能需要在现有的可摘局部义齿下制作冠。通常，一旦制作了牙冠，就需要对义齿进行修改或重新制作。但是，如果局部义齿临床状况良好，可以应用特殊技术来使新牙冠与现有的义齿相适配。本文介绍了一种在现有的可摘局部义齿下用热水制作铸造金属冠的简单间接-直接技术。该技术不需要专业知识或任何特殊设备，一般牙医可以在椅旁进行操作。
