摘　　要：正畸牙移动即施加正畸力将牙齿移动到上下颌骨内的所需位置。在此过程中,牙根可能会与颌骨内的神经管结构(如下颌神经管和切牙管)紧密接触,出现神经损伤的风险。此外,由于神经位于神经管内,牙根先接触骨皮质也可能导致牙根吸收的风险。本文综述国内外相关研究,探讨了正畸牙移动相关的神经压迫,提示正畸医生需要注意到神经管存在受压的潜在风险,对于高风险病例应采取必要的预防措施以降低风险。Orthodontic tooth movement is to move the tooth to a desired position in the upper and lower jaw by orthodontic force.In this process,the tooth root may be in close contact with some neural canal structures in the jaw,such as the Mandibular canal and the incisive canal,which may lead to the risk of nerve injury.In addition,because the nerve is located in the nerve canal,the tooth root first contacts the bone cortex,which may also lead to the risk of tooth root absorption.This article reviews the relevant research at home and abroad,and discusses the nerve compression related to orthodontic tooth movement.At the same time,orthodontists need to be aware of the potential risk of neural canal compression and take necessary preventive measures to reduce the risk for related high-risk cases.
