摘要： 正畸治疗中,大幅内收上前牙常导致牙根吸收,影响治疗效果的稳定性。近年来,随着锥形束计算机断层扫描技术的发展,研究者们发现切牙管可能在这一过程中起到关键作用。然而,目前尚无系统性研究明确切牙管的形态特征及其在牙根吸收中的具体作用,且缺乏足够的相关临床数据。目前人工智能在医学影像分析中的应用,使牙根吸收的预测和预防成为可能,但此类预测需要基于大量前期研究数据。因此,探讨切牙管的形态和大小、切牙管与切牙的位置关系、切牙管重建与上颌中切牙牙根吸收的相关性,不仅有助于优化前牙内收的正畸方案,还能为减少牙根吸收提供新思路。

Abstract: In orthodontic treatment, massive retraction of the maxillary central teeth often leads to root resorption, which can affect the stability of treatment outcomes. In recent years, with the development of cone-beam computed tomography (CBCT) technology, researchers have discovered that the incisive canal may play a crucial role in this process. However, there are currently no systematic studies clarifying the specific role of the morphological characteristics of the incisive canal in root resorption, and sufficient clinical data to support these hypotheses are lacking. Currently, the application of artificial intelligence in medical image analysis has gradually made it possible to predict and prevent root resorption, which means large amounts of data are required to ensure the accuracy of predictions. Therefore, a detailed investigation about the morphology and size of the incisive canal, the positional relationship between the incisive canal and the incisors, and the correlation between incisive canal reconstruction and root resorption of maxillary central incisors is necessary, which could not only optimize orthodontic treatment plans for anterior tooth retraction, but also offer new approaches for minimizing the risk of root resorption.
