外伤牙早期固定正畸治疗的研究进展

Research progress on early fixed orthodontic treatment of traumatic teeth

摘要

外伤牙的正畸移动是正畸治疗中较常见的难题。尽管已有大量关于外伤牙正畸治疗的研究，但关于不同牙外伤类型、不同创伤程度的外伤牙正畸治疗的最佳方法与治疗时机尚未达成共识。近年，较多学者认为早期开始正畸治疗可以增加外伤牙治疗的成功率并减少牙根粘连的发生。但也有研究显示，外伤牙正畸治疗后可能会出现牙根吸收、牙髓坏死、牙髓钙化。在开始正畸治疗之前记录牙外伤史，全面评估牙外伤患者正畸治疗的收益与风险，对于制定适当的正畸治疗计划是非常重要的。本文就外伤牙早期固定正畸治疗的研究进展进行了综述，以期为相关临床工作提供参考。

Abstract

The orthodontic movement of traumatic teeth is a common problem in orthodontic treatment. Although the orthodontic treatment of traumatic teeth has been studied, no consensus has been reached regarding the best method and timing of treatment for different types and severity of dental trauma. Many researchers agreed that starting orthodontic treatment early could increase the success rate of treatment and avoid tooth ankylosis. However, some studies showed that the orthodontic treatment of traumatic teeth might increase the risk of root resorption, pulp necrosis, and canal obliteration. Therefore, recording the history of dental trauma and comprehensively evaluating the risk for patients with dental trauma are crucial before orthodontic treatment. In this work, studies on the early orthodontic treatment of traumatic teeth were reviewed to provide a reference for related clinical practice.
