摘　　要：上颌阻生尖牙是临床上常见的难题。早期对可能发生阻生的上颌尖牙进行干预,常常可以减轻其阻生的严重程度,甚至可以使尖牙正常萌出。临床上常通过影像学方法对上颌尖牙阻生进行早期预测。其中影像学检查不仅包括传统的全口曲面体层片等二维影像,也包括近年来发展比较迅速的锥形束CT三维影像。本文通过回顾以往研究来总结目前影像学预测上颌尖牙阻生的研究进展,以指导临床早期预测上颌尖牙阻生并选择合适的干预时机。Maxillary canine impaction is a common dental problem.Predicting the potential of maxillary canines to become impacted at an early stage often reduces the severity of impaction and even allows the canines to erupt normally.Maxillary canine impaction can be predicted early by radiography.Radiographic tools include not only traditional twodimensional radiographs,such as panoramic films,but also three-dimensional images obtained via cone-beam computed tomography,which was developed only recently.In this review,we summarized current progress in the early prediction of maxillary impacted canines via radiological examinations to guide the clinical prediction of maxillary canine impaction and the assessment of optimal treatment timing.
