Statement of the problem Digital workflows (CAD/CAM) have been introduced in dentistry during recent years. No published information exists on dentists' use and reporting of this technology.Purpose The purpose of this survey was to identify the infiltration of CAD/CAM technology in UK dental practices and to investigate the relationship of various demographic factors to the answers regarding use or non-use of this technology.Materials and methods One thousand and thirty-one online surveys were sent to a sample of UK dentists composing of both users and non-users of CAD/CAM. It aimed to reveal information regarding type of usage, materials, perceived benefits, barriers to access, and disadvantages of CAD/CAM dentistry. Statistical analysis was undertaken to test the influence of various demographic variables such as country of work, dentist experience, level of training and type of work (NHS or private).Results The number of completed responses totalled 385. Most of the respondents did not use any part of a digital workflow, and the main barriers to CAD/CAM use were initial costs and a lack of perceived benefit over conventional methods. Dentists delivering mostly private work were most likely to have adopted CAD/CAM technology (P <0.001). Further training also correlated with a greater likelihood of CAD/CAM usage (P <0.001). Most users felt that the technology had led to a change in the use of dental materials, leading to increased use of, for example, zirconia and lithium disilicate. Most users were trained either by companies or self-trained, and a third felt that their training was insufficient. The majority of respondents (89%) felt that CAD/CAM had a big role to play in the future.Conclusion Most of the respondents did not use any part of a digital workflow. However, the majority of surveyed dentists were interested in incorporating CAD/CAM into their workflow, while most believed that it will have a big role in the future. There are still some concerns from dentists about the quality of chairside CAD/CAM restorations while the costs are still in the main hugely prohibitive (especially for NHS dentistry).
问题陈述 近年来，数字工作流程（CAD/CAM）已被引入牙科领域。目前尚无关于牙医对该技术的使用情况及报告的公开信息。
目的 本次调查的目的是确定CAD/CAM技术在英国牙科诊所的渗透情况，并调查各种人口统计学因素与关于该技术使用或不使用的回答之间的关系。
材料与方法 向由CAD/CAM用户和非用户组成的英国牙医样本发送了1031份在线调查问卷。旨在揭示有关使用类型、材料、感知到的益处、获取障碍以及CAD/CAM牙科的缺点等信息。进行了统计分析，以测试各种人口统计学变量的影响，如工作国家、牙医经验、培训水平和工作类型（国民保健服务体系或私人执业）。
结果 完成的回复总数为385份。大多数受访者未使用数字工作流程的任何部分，而CAD/CAM使用的主要障碍是初始成本以及相较于传统方法缺乏感知到的益处。主要从事私人执业工作的牙医最有可能采用CAD/CAM技术（P<0.001）。进一步培训也与CAD/CAM使用的可能性更大相关（P<0.001）。大多数用户认为该技术导致了牙科材料使用的变化，例如氧化锆和二硅酸锂的使用增加。大多数用户是由公司培训或自学的，三分之一的人认为他们的培训不足。大多数受访者（89%）认为CAD/CAM在未来将发挥重要作用。
结论 大多数受访者未使用数字工作流程的任何部分。然而，大多数接受调查的牙医有兴趣将CAD/CAM纳入其工作流程，同时大多数人认为它在未来将发挥重要作用。牙医们仍对椅旁CAD/CAM修复体的质量存在一些担忧，而成本在很大程度上仍然过高（特别是对于国民保健服务体系牙科）。
