[Research and development of digital design and fabrication of complete denture].

Removable complete denture are still the primary prosthetic solution for edentulous patients. Functional pressure impression obtaining, jaw relation recording, personalized balance occlusion and highly precise fabrication of denture are difficult. The digital restoration technique represented by intraoral three-dimensional scanning and three-dimensional (3D) printing compensates for the shortages of the manual techniques, but there are still many limitations in the application of complete dentures. At present, a few computer aided design and computer aided manufacture (CAD/CAM) complete denture systems have been developed both domestically and abroad, and these system are mainly focused on the digital design and manufacture of denture, and are seldom used for the recording of impression and jaw relation. This review is based on the main clinical procedures of the traditional complete denture restoration, elaborating the research and application status of digital technique in each steps, in order to provide reference for clinical application.全口义齿是无牙颌患者的主要修复方式，功能压力印模、颌位关系记录、平衡 排牙以及义齿的高精度制作是关键环节和操作难点。以口内三维扫描、三维打印为代表的数字化技术弥补了纯手工技术的不足，在固定修复领域应用日趋广泛，但应用于全口义齿时存在局限性。目前，国内外已出现多套全口义齿数字修复系统，均主要聚焦于全口义齿的数字化设计和制作，较少有印模和颌位关系数字化记录功能。本文以无牙颌常规全口义齿修复的主要临床步骤为线索，详述数字化技术在各环节的研发和应用现状，为临床决策提供参考。.
