中文摘要
根尖区牙根外吸收（EARR）是口腔正畸治疗中最常见的风险之一，难以预测，且不能完全避免。正畸EARR的风险因素目前尚不明确，一般可分为患者相关因素和治疗相关因素。正畸治疗中发生的EARR通常可在影像学检查时发现。轻、中度EARR通常无明显危害，可密切关注，谨慎正畸；若发生重度EARR，则建议先暂停正畸加力，观察3个月，等待牙骨质的修复。为进一步规范和提高临床医生对正畸EARR的认识，本文邀请了全国20余位口腔正畸及相关领域专家，基于文献分析与讨论，制定出此共识，为正畸临床提供参考。
英文摘要
External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.
