To provide a narrative overview of commercially available CBCT devices, highlight the wide range of technical features and their impact on image quality and diagnostic performance, and develop decision support charts to guide clinicians in selecting appropriate CBCT parameters for different dental specialties.
Data collection involved reviewing published articles on CBCT devices and accessing manufacturer websites. Additional manufacturers were identified through a literature search and by attending scientific and commercial events held in 2023 and 2024. Information on CBCT features was obtained from websites, manuals, and inquiries until February of 2025. Data were categorized and analyzed descriptively and quantitatively to recommend device requirements for dental specialties. Decision support charts were developed for each specialty based on common indications and technical parameters (e.g., field-of-view, scout need, spatial resolution, X-ray exposure parameters, and post-processing tools).
Eighty-seven commercially available CBCT devices from 34 manufacturers across 11 countries were identified, with information confirmed for only 10 companies. Missing data varied, however FOV and voxel size were commonly reported. Tube voltage ranged from 50-120 kV, and tube current mostly varied between 1-17 mA. Dose considerations varied widely, with dose-product-area ranging from 10 to 5600 mGy.cm2 and typical effective dose estimates from 3 to 500 µSv. Decision support charts were created, outlining necessary image acquisition and reconstruction-related parameters for prosthodontics and implant dentistry, periodontology, oral and maxillofacial surgery, pediatric dentistry and orthodontics, and endodontics.
This study provides an overview of the technical features of commercially available CBCT devices, highlighting gaps in reconstruction parameters and dose considerations. Tailored recommendations based on patient-specific needs are essential, with clinicians individualizing CBCT acquisition to optimize diagnostic accuracy and minimize biological risks.
This study provides valuable insights into commercially available CBCT devices in terms of their features and provides decision support chart to help clinicians select optimal technical parameters tailored to specific dental specialties.
对市售锥形束计算机断层扫描（CBCT）设备进行叙述性概述，突出其广泛的技术特征及其对图像质量和诊断性能的影响，并制定决策支持图表，以指导临床医生为不同牙科专业选择合适的CBCT参数。
数据收集包括查阅关于CBCT设备的已发表文章并访问制造商网站。通过文献检索以及参加2023年和2024年举办的科学和商业活动，确定了更多制造商。直到2025年2月，有关CBCT特征的信息是从网站、手册和咨询中获取的。对数据进行分类，并进行描述性和定量分析，以推荐牙科专业的设备要求。根据常见适应症和技术参数（例如视野、定位需求、空间分辨率、X射线曝光参数和后处理工具）为每个专业制定决策支持图表。
确定了来自11个国家34家制造商的87种市售CBCT设备，仅10家公司的信息得到确认。缺失数据各不相同，但视野和体素大小通常有报告。管电压范围为50 - 120 kV，管电流大多在1 - 17 mA之间变化。剂量考量差异很大，剂量 - 乘积 - 面积范围为10至5600 mGy.cm²，典型有效剂量估计值为3至500 μSv。创建了决策支持图表，概述了口腔修复学与种植牙科、牙周病学、口腔颌面外科、儿童牙科与正畸学以及牙髓病学所需的图像采集和重建相关参数。
本研究概述了市售CBCT设备的技术特征，突出了重建参数和剂量考量方面的差距。根据患者的具体需求提供量身定制的建议至关重要，临床医生应根据个体情况调整CBCT采集，以优化诊断准确性并将生物风险降至最低。
本研究在市售CBCT设备的特征方面提供了有价值的见解，并提供决策支持图表，以帮助临床医生选择适合特定牙科专业的最佳技术参数。
