摘　　要：上颌中切牙位置直接影响患者矫治结束后面部轮廓对称性及中线协调,在制定正畸诊疗计划时,上颌中切牙的目标三维空间位置需重点关注。随着CBCT的广泛应用,学者们发现上中切牙的实际后界不仅与上颌骨腭侧骨皮质有关,更与切牙管形态密切相关。了解切牙管的形态及在其正畸矫治中的临床意义有助临床医师制定治疗计划、过程监控以及术后评估。本文就切牙管的形态结构及其在正畸矫治中的临床意义作一综述。The position of maxillary central incisors directly affects facial contour symmetry and midline coordination after orthodontic treatment.Therefore,the three-dimensional spatial angle of maxillary central incisors should be considered when making orthodontic treatment plan.With the wide application of CBCT,scholars found that the root resorption of maxillary central incisors was not only related to the palatal cortex of the maxilla,but also closely related to the shape of the incisor canal.Therefore,understanding the shape of incisor canal and its clinical significance in orthodontic treatment can provide guidance for clinicians in the formulation of treatment plans,process monitoring,and postoperative evaluation.This article reviews the structure of incisor canal and its clinical significance in orthodontic treatment.
