Cone beam computed tomography (CBCT) has the potential to reduce the size and cost of CT scanners. This emerging technology produces images with isotropic sub-millimeter spatial resolution with high diagnostic quality, short scanning times of about 10-30 seconds, and radiation dosages of up to 15 times lower than those of conventional CT scans. It is ideally suited for dedicated dentomaxillofacial CT scanning. This technology provides dental practitioners with complete solution for performing specific diagnostic and clinical tasks, including implant planning, temporomandibular joint evaluation, facial fractures, dentoalveolar surgery, orthognathic surgery and periodontal surgery. CBCT is capable of providing a 3-dimensional representation of the maxillofacial hard tissues with minimal distortion. The objective of this article is to highlight the clinical applications of CBCT to oral and maxillofacial surgeons and other dental specialists in Nigeria.
锥形束计算机断层扫描（CBCT）有潜力减小CT扫描仪的尺寸并降低成本。这项新兴技术能生成具有各向同性亚毫米空间分辨率的图像，诊断质量高，扫描时间短，约为10 - 30秒，辐射剂量比传统CT扫描低多达15倍。它非常适合专用的牙颌面CT扫描。这项技术为牙科医生提供了执行特定诊断和临床任务的完整解决方案，包括种植规划、颞下颌关节评估、面部骨折、牙槽外科手术、正颌外科手术和牙周手术。CBCT能够以最小的失真提供颌面硬组织的三维表示。本文的目的是向尼日利亚的口腔颌面外科医生和其他牙科专家强调CBCT的临床应用。
