As is the case in the field of medicine, as well as in most areas of daily life, digital technology is increasingly being introduced into dental practice. Computer-aided design/ computer-aided manufacturing (CAD/CAM) solutions are available not only for chairside practice but also for creating inlays, crowns, fixed partial dentures (FPDs), implant abutments, and other dental prostheses. CAD/CAM dental practice can be considered as the handling of devices and software processing for the almost automatic design and creation of dental restorations. However, dentists who want to use dental CAD/CAM systems often do not have enough information to understand the variations offered by such technology practice. Knowledge of the random and systematic errors in accuracy with CAD/CAM systems can help to achieve successful restorations with this technology, and help with the purchasing of a CAD/CAM system that meets the clinical needs of restoration. This article provides a mechanical engineering viewpoint of the accuracy of CAD/ CAM systems, to help dentists understand the impact of this technology on restoration accuracy.
与医学领域以及日常生活的大多数领域一样，数字技术正越来越多地被引入牙科实践。计算机辅助设计/计算机辅助制造（CAD/CAM）解决方案不仅可用于椅旁操作，还可用于制作嵌体、牙冠、固定局部义齿（FPD）、种植基台和其他牙科修复体。CAD/CAM牙科实践可被视为对设备和软件进行处理，以近乎自动地设计和制作牙科修复体。然而，想要使用牙科CAD/CAM系统的牙医往往没有足够的信息来了解这种技术实践所提供的差异。了解CAD/CAM系统在精度方面的随机误差和系统误差，有助于利用该技术成功完成修复，并有助于购买满足修复临床需求的CAD/CAM系统。本文从机械工程的角度阐述CAD/CAM系统的精度，以帮助牙医了解该技术对修复精度的影响。
