A clinical and laboratory workflow for fabricating and retrofitting a monolithic ceramic crown to an existing removable partial denture (RPD) is described. A conventional polyvinyl siloxane impression was made of the prepared tooth with the RPD in place. A stone cast was poured and, after die sectioning, scanned with a tabletop scanner. The ceramic crown was designed and fabricated by using a digital workflow to fit the RPD clasp assembly, providing an adequate undercut for the clasp. The crown was then delivered and the RPD evaluated for adequate fit.

模拟和数字相结合的工作流程，用于将整体式陶瓷牙冠翻新为现有的可摘局部义齿

描述了一种用于将整块陶瓷牙冠制造和翻新为现有可移动局部义齿（RPD）的临床和实验室工作流程。用准备好的RPD制成的牙齿制成常规的聚乙烯基硅氧烷印模。倒入一块石头铸件，在切片后，用台式扫描仪进行扫描。通过使用数字工作流程来设计和制造陶瓷表冠，以适合RPD扣环组件，为扣环提供足够的底切。然后交付牙冠，并评估RPD是否合适。
