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.
介绍了一种制作和改装整体陶瓷冠到现有可摘局部义齿（RPD）的临床和实验室工作流程。通过在 RPD 就位的情况下对准备好的牙齿进行常规聚硅氧烷印模。浇铸石模型，然后在切片后用台式扫描仪进行扫描。通过数字工作流程设计和制作陶瓷冠，以适应 RPD 卡环组件，为卡环提供足够的固位形。然后交付冠并评估 RPD 的适配性。
