Gingival recession can be defined as the apical shift of the marginal gingiva from its normal position on the crown of the tooth to levels on the root surface beyond the cemento-enamel junction. The aetiology of this condition is multifactorial, but can result from a traumatic occlusion. The long-term prognosis of teeth with localised gingival recession can be uncertain. Successful management of these cases may involve either orthodontic or periodontal treatment in isolation or in combination.
To describe two patients in which localised gingival recession associated with anterior crossbites were corrected with orthodontic appliances.
A 2 x 4 appliance and an upper removable appliance were used to correct the crossbites.
Correction of the anterior crossbites resulted in a clinical improvement of the gingival recession. The aetiology and management of localised gingival recession is discussed.
Simple orthodontic appliances can be used to provide interceptive treatment to correct localised crossbite and enhance the overall long-term prognosis of the lower incisors. To achieve optimal results multidisciplinary involvement is recommended.
牙龈退缩可定义为边缘龈从牙冠上的正常位置向牙骨质-釉质界以外的牙根表面水平的根尖向移位。这种情况的病因是多因素的，但可能由创伤性咬合引起。局部牙龈退缩牙齿的长期预后可能不确定。这些病例的成功治疗可能单独或联合采用正畸或牙周治疗。
描述两例通过正畸矫治器矫正与前牙反合相关的局部牙龈退缩的患者。
使用2×4矫治器和上颌活动矫治器矫正反合。
前牙反合的矫正导致牙龈退缩的临床改善。讨论了局部牙龈退缩的病因和治疗。
简单的正畸矫治器可用于提供阻断性治疗，以矫正局部反合并改善下前牙的整体长期预后。为获得最佳效果，建议多学科参与。
