[Understanding chair-side digital technology for stomatology from an engineering viewpoint].

In recent years with the rapid development of digital technology for stomatology, the application field, application model, technical features and technical connotation of the chair-side digital technology has got development and change. The open modular system has gradually replaced the traditional closed system, and the application field of digital technology is no longer limited to chair-side dental restoration, it also has been extend to various kinds of chair-side digital treatment-assisted technology. In this paper, from the engineering point of view, the up to date general connotation of chair-side digital technology was explained, the characteristics and the development of each unit in chair-side digital technology were analyzed, and the application pattern and the localization status were also discussed in this paper. The aim of this paper was to introduce the trend of chair-side digital technological to readers and to better guide clinical application.近年随着口腔医学数字化技术的快速发展，椅旁数字化技术的应用范围、应用模式、技术特点和技术内涵也随之发展和变化，开放的组合式系统逐渐替代传统封闭式系统，应用范围也不再局限于椅旁修复，拓展延伸至各种椅旁数字化辅助治疗技术。本文从工程技术角度阐述椅旁数字化技术现今的广义内涵，分析各椅旁数字化单元技术的特点和发展现状，并对椅旁数字化技术应用模式和国产化现状进行探讨，以期分析技术发展的动态和趋势，从而更好地指导临床应用。.
