Research Progress on Effect of Incisal Canal on Root Resorption during Retraction of Maxillary Central Incisors

Abstract

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.
