[Advances in computer aided design and computer aided manufacturing of removable partial denture].

Computer aided design, numerically controlled milling, additive manufacturing and other digital technologies have been widely used in clinical practice of prosthodontics. The application of these technologies not only changed the design and manufacturing workflow of removable partial denture (RPD), but also improved the production efficiency of dentures, and changed the design and manufacturing concept of dentures. A large number of researches on computer aided design and computer aided manufacturing (CAD/CAM) of RPD have emerged in recent years, including researches on the properties of selective laser melting metal powder and other new dental materials, the innovative design of retainers, connectors, artificial teeth and other denture components, high precision manufacturing of the RPD framework, denture base and artificial teeth, quantitative laboratory evaluations of the accuracy, adaption and mechanical properties of RPD with new structures and made of new materials, clinical evaluations of RPD and others. This paper introduces these recent developments in CAD/CAM of RPD. 计算机辅助设计、数控切削、增材制造等数字化技术越来越广泛地应用于口腔修复临床。这些技术的应用不仅改变了可摘局部义齿的设计和制作流程，提高了义齿生产效率，而且改变了义齿的设计和制作理念。关于可摘局部义齿计算机辅助设计与辅助制作的研究方兴未艾，近年涌现了大量研究报道，包括选区激光熔化金属粉末等新材料的性能研究，义齿固位体、连接体、人工牙等组件的创新性设计，支架、基托和人工牙的高精度成形，应用新材料、具有新结构的可摘局部义齿的精度、适合性和力学性能定量评价，以及对可摘局部义齿的临床评价等诸多方面，本文针对近年可摘局部义齿计算机辅助设计与辅助制作研究应用最新进展进行系统论述。.
