The components and dimensions of the periodontal and peri‐implant phenotype have a high relevance in contemporary dental research and should be taken into consideration in the decision‐making process in the management of a variety of clinical scenarios to optimize the outcomes of therapy. Various assessment methods for quantifying and classifying the phenotypical dimensions have emerged and developed in recent decades. Nevertheless, the use of cone‐beam computed tomography (CBCT) scans remains the most commonly used approach worldwide. However, the accuracy to adequately imaging and measuring the dimensions of the hard and soft tissue components around teeth may represent a significant challenge in different clinical scenarios due to factors such as the age of the patient and motion during the scan, presence of metallic artifacts causing streaks and gray‐value distortion, overlapping of soft tissue structures, machine performance, file processing, and small voxel size among others. These factors pose a particular challenge when tiny structures are under investigation, for example, the buccal/lingual bony or soft tissue layer of lower/upper incisors. Therefore, this review addresses the underlying technical information of the use of CBCT scans, and suggests some recommendations on the utilization of this method of assessment to optimally use it despite its' system‐inherent limitations.

锥形束计算机断层扫描对牙周表型组成部分成像的准确性


牙周和种植体周围表型的组成和维度在当代牙科研究中具有高度相关性，应在管理各种临床情况的决策过程中予以考虑，以优化治疗结果。近几十年来，出现并发展了用于对表型维度进行量化和分类的各种评估方法。尽管如此，锥束计算机断层扫描 (CBCT) 扫描的使用仍然是全球最常用的方法。然而，由于患者年龄、扫描过程中的运动、金属伪影的存在等因素，牙齿周围硬组织和软组织成分尺寸的充分成像和测量的准确性可能在不同的临床场景中构成重大挑战。条纹和灰度值失真、软组织结构重叠、机器性能、文件处理和小体素尺寸等。当研究微小结构时，例如下/上切牙的颊/舌骨或软组织层，这些因素构成了特殊的挑战。因此，本综述讨论了使用 CBCT 扫描的基本技术信息，并提出了一些关于使用这种评估方法的建议，以最佳地使用它，尽管它有系统固有的局限性。
