Applications of cone-beam CT (CBCT) in orthodontics have been increasingly discussed and evaluated in science and practice over the last two decades. The present work provides a comprehensive summary of current consolidated practice guidelines, cutting-edge innovative applications, and future outlooks about potential use of CBCT in orthodontics with a special focus on upper airway analysis in patients with sleep-disordered breathing. The present scoping review reveals that clinical applications of CBCT in orthodontics are broadly supported by evidence for the diagnosis of dental anomalies, temporomandibular joint disorders, and craniofacial malformations. On the other hand, CBCT imaging for upper airway analysis-including soft tissue diagnosis and airway morphology-needs further validation in order to provide better understanding regarding which diagnostic questions it can be expected to answer. Internationally recognized guidelines for CBCT use in orthodontics are existent, and similar ones should be developed to provide clear indications about the appropriate use of CBCT for upper airway assessment, including a list of specific clinical questions justifying its prescription.
在过去的二十年中，锥形束 CT（CBCT）在正畸学中的应用在科学和实践中得到了越来越多的讨论和评估。本研究全面总结了当前关于 CBCT 在正畸学中应用的既定实践指南、前沿创新应用以及未来展望，特别关注睡眠呼吸障碍患者的上气道分析。本范围综述表明，CBCT 在正畸学中的临床应用得到了广泛的证据支持，可用于诊断牙齿异常、颞下颌关节紊乱和颅面畸形。另一方面，上气道分析的 CBCT 成像——包括软组织诊断和气道形态——需要进一步验证，以便更好地了解它可以回答哪些诊断问题。正畸学中使用 CBCT 的国际公认指南已经存在，应该制定类似的指南，以提供明确的适应症，说明 CBCT 在上气道评估中的适当使用，包括一份可证明其处方合理性的具体临床问题清单。
