A correct orthodontic diagnosis needs to be based on accurate images of the craniofacial region and is crucial for the development of a valid treatment plan. A cone-beam computed tomography (CBCT) scanner allows 3D imaging of the craniofacial complex. CBCT scanners represent a significant advantage in imaging capabilities for dentistry and orthodontics, replacing conventional 2D radiographic images with 3D data sets and only a small increase in radiation. The present study surveys the rationale, advantages, and disadvantages of the available CBCT appliances and presents answers to questions often asked in relation to this technology.
正确的正畸诊断需要基于颅面部区域的精确图像，这对于制定有效的治疗方案至关重要。锥形束计算机断层扫描（CBCT）扫描仪可对颅面部复合体进行三维成像。CBCT扫描仪在牙科和正畸的成像能力方面具有显著优势，它用三维数据集取代了传统的二维放射图像，且辐射仅略有增加。本研究调查了现有CBCT设备的原理、优缺点，并回答了与该技术相关的常见问题。
