牙龈退缩作为正畸治疗中常见的并发症，不仅会引起牙根部牙本质敏感，牙颈和牙根部龋坏，牙周支持丧失，食物嵌塞，还会严重影响患者的容貌美观。牙龈退缩是多因素共同作用的结果，好发于前牙区和颌骨左侧，共分4度，50%以上的健康人群均可发病，退缩程度随着人的年龄增加而加重。其治疗首选非手术方法，即在正畸治疗过程中和治疗结束后注意炎症的控制，调，去除食物嵌塞发病因素；手术治疗主要有软组织移植术和引导组织再生术，前者通过皮瓣移植，后者促进牙周软硬组织的再生；若非手术和手术方法均不能有效地实现牙龈生理性重建，则可以采用修复方法对其进行掩饰性治疗，即人工龈修复。

Gingival recession is a common complication during orthodontic treatment that causes root dentin hypersensitivity, root caries, loss of periodontal support, and food impaction, and it may affect the appearance of patients. Gingival recession is caused by multiple factors, and it usually occurs in the anterior teeth and left side of the mandible. Gingival recession is divided into four classes. More than 50% of the healthy population have gingival recession and the degree of gingival recession is aggravated by increasing age. The preferred treatment for gingival recession is nonsurgical and involves controlling inflammation, occlusal grinding, and removing the etiology of food impaction during and after orthodontic treatment. The surgical methods include soft-tissue grafting through flap transplantation and guided tissue regeneration through regeneration of periodontal tissue. Gingival veneers can be used to restore the shape of the gingiva if nonsurgical and surgical methods are ineffective in physiologic gingival reconstruction.
