摘　　要：背景:近年来国内外学者对数字化全口义齿的研究逐渐增多,相比传统全口义齿,其具有减少患者复诊次数、节约临床时间、提高制作精度等诸多优点。目的:综述数字化全口义齿的技术发展和临床应用情况,并分析其现有不足。方法:应用计算机检索1980至2017年Pub Med、CNKI、万方等数据库,检索词为"CAD/CAM complete dentures、digital complete dentures,rapid prototyping dentures,manufactured dentures,computer dentures,machined dentures,designed dentures,milled dentures,artificial tooth,3D scanning,3D printing;全口义齿,数字化,CAD,CAM,计算机辅助设计与计算机辅助制造,人工牙,三维扫描,铣销,3D打印,快速成型"。结果与结论:目前数字化全口义齿制作还不能完全实现数字化,制取数字化印模时,传统方式取模后扫描牙颌模型的间接方式仍是主流的数据采集技术。将来,直接扫描患者牙槽嵴及其周围软组织,直接数字化确定颌位关系等技术问题有待继续解决。开发强度、美观、舒适度适合的新性能3D打印人工牙及基托材料,将人工牙和基托整体3D打印出来作为最终义齿等改进,将会使数字化义齿技术越来越成熟。BACKGROUND： In recent years, increasing studies focus on digital complete denture. Digital complete denture has many advantages such as reducing patient visit times, saving chairside time, improving manufacturing precision in comparison with traditional complete denture.OBJECTIVE： To review the development of technology and clinical application of digital complete denture,and to analyze the existing insufficiencies.words were ＂CAD/CAM complete dentures, digital complete dentures, rapid prototyping dentures, manufactured dentures, computer dentures, machined dentures, designed dentures, milled dentures, artificial tooth, 3D scanning, 3D printing＂ in English and Chinese, respectively.RESULTS AND CONCLUSION： Currently, the production of complete denture using digital technology cannot be fully realized. During digital impression, to scan the traditional dental casts is still the mainstream technology for data acquisition technology. Future investigations on scanning the patient alveolar ridge and its surrounding soft tissue directly and digitally recording the jaw relation directly are warranted. To develop 3D-printed artificial teeth and base materials with proper strength, aesthetics, comfort levels as well as 3D printing of the artificial tooth and the base as the final denture will make digital denture technology more mature.
