数字化全口义齿技术的发展和临床应用

发布时间：2018-12-17 06:49

【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。
[Abstract]:Background: in recent years, the research on digital complete denture has been increasing gradually. Compared with traditional complete denture, it has many advantages, such as reducing the number of visits, saving clinical time and improving the manufacturing accuracy. Objective: to review the technical development and clinical application of digital complete denture and analyze its shortcomings. Methods: Pub Med,CNKI, Wanfang database was searched by computer from 1980 to 2017 with the key words "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;". Complete denture, digital, CAD,CAM, computer aided design and computer-aided manufacturing, artificial teeth, 3D scanning, milling pin, 3D printing, rapid prototyping. Results & conclusion: at present, digital complete denture can not be fully digitized. When making digital impression, the traditional indirect method of scanning dental and maxillary model is still the mainstream data acquisition technology. In the future, the technical problems such as direct scanning of alveolar ridge and its surrounding soft tissue and direct digital determination of maxillary position need to be solved. Developing new properties of strength, beauty and comfort suitable for 3D printing artificial teeth and base materials, and using artificial teeth and bases as final dentures will make digital denture technology more and more mature.
