To examine the increased use of chairside CAD/CAM among Chinese dental practitioners, and to explore the existing barriers influencing its further application and satisfaction levels.
A semi-structured questionnaire was developed to gather respondents' demographic information, as well as their experiences and behaviours regarding the implementation of chairside CAD/CAM. A specialised web-based survey system and WeChat were used to display and distribute the final questionnaire. Then, the data were analysed with Chi-square tests and regression analyses to determine the effects of various demographic variables on chairside CAD/ CAM applications.
A total of 1,969 questionnaire responses were included in the analyses. Chairside CAD/ CAM systems were used by 36.9% of participants, with a higher usage rate observed among prosthodontists (60.0%) and dental practitioners holding a PhD degree (57.7%). Chairside CAD/ CAM-fabricated prostheses were most commonly used in the posterior maxilla (83.3%) and mandible (86.0%), followed by the anterior maxilla and mandible (63.8% and 48.6%, respectively). Major barriers to further application included high initial investment, frequent updates of equipment and software programs, and a lack of expertise in chairside CAD/CAM usage.
Most dental practitioners did not use chairside CAD/CAM systems. The application rate was significantly influenced by sex, location, educational background, department and type of healthcare facility. Chairside CAD/CAM users showed limited satisfaction with the aesthetic performance of the fabricated prostheses. To improve the popularity of chairside CAD/CAM systems, especially among dental practitioners lacking advanced academic degrees, it is highly advisable to optimise CAD software programs and offer comprehensive training opportunities.
研究中国牙科医生中椅旁 CAD/CAM 使用的增加情况，并探讨影响其进一步应用和满意度的现有障碍。
设计了一份半结构式问卷，以收集受访者的人口统计学信息，以及他们在实施椅旁 CAD/CAM 方面的经验和行为。使用专门的网络调查系统和微信展示和分发最终问卷。然后，使用卡方检验和回归分析来确定各种人口统计学变量对椅旁 CAD/CAM 应用的影响。
共纳入了 1969 份问卷的分析。36.9%的参与者使用了椅旁 CAD/CAM 系统，其中修复科医生（60.0%）和拥有博士学位的牙科医生（57.7%）的使用率更高。椅旁 CAD/CAM 制作的修复体最常用于上颌后牙（83.3%）和下颌（86.0%），其次是上颌前牙和下颌前牙（分别为 63.8%和 48.6%）。进一步应用的主要障碍包括初始投资高、设备和软件程序频繁更新以及缺乏椅旁 CAD/CAM 使用方面的专业知识。
大多数牙科医生未使用椅旁 CAD/CAM 系统。应用率受到性别、地点、教育背景、科室和医疗机构类型的显著影响。椅旁 CAD/CAM 用户对制作修复体的美学性能满意度有限。为了提高椅旁 CAD/CAM 系统的普及性，特别是在缺乏高级学术学位的牙科医生中，优化 CAD 软件程序并提供全面的培训机会是非常可取的。
