The application of innovative technologies in dentistry and orthodontics has been very interesting to observe. The development of cone-beam computed tomography (CBCT) as a preferred imaging procedure for comprehensive orthodontic treatment is of particular interest. The information obtained from CBCT imaging provides several substantial advantages. For example, CBCT imaging provides accurate measurements, improves localization of impacted teeth, provides visualization of airway abnormalities, it identifies and quantifies asymmetry, it can be used to assess periodontal structures, to identify endodontic problems, to plan placement sites for temporary skeletal anchorage devices, and to view condylar positions and temporomandibular joint (TMJ) bony structures according to the practitioner's knowledge at the time of orthodontic diagnosis. Moreover, CBCT imaging involves only a minimal increase in radiation dose relative to combined diagnostic modern digital panoramic and cephalometric imaging. The aim of this article is to provide a comprehensive overview of CBCT imaging, including its technique, advantages, and applications in orthodontics.
观察创新技术在牙科和正畸学中的应用一直非常有趣。锥形束计算机断层扫描（CBCT）作为综合正畸治疗的首选成像程序的发展尤其令人关注。从CBCT成像获得的信息具有几个显著优势。例如，CBCT成像提供准确的测量，改善阻生牙的定位，提供气道异常的可视化，识别和量化不对称性，可用于评估牙周结构、识别牙髓问题、规划临时骨锚固装置的放置部位，以及根据正畸诊断时从业者的知识查看髁突位置和颞下颌关节（TMJ）骨结构。此外，相对于现代数字化全景和头影测量联合诊断成像，CBCT成像仅使辐射剂量有极小的增加。本文的目的是全面概述CBCT成像，包括其技术、优势以及在正畸学中的应用。
