Gingival invagination is a relatively common occurrence following orthodontic closure of extraction sites. The present paper reports a combined periodontal and orthodontic treatment in a patient with a severe gingivo-alveolar cleft due to orthodontic closure of maxillary central incisor extraction space.
A definite interdental gingival cleft, extending 8 mm into the alveolar bone, required the correction of the gingival deformity as a first step, followed by guided bone regeneration (GBR). The GBR approach included the emptying of the incisive foramen to approximately 5 mm in depth followed by the insertion of bioabsorbable hydroxyapatite and covering with a bioabsorbable barrier membrane. Six months afterward, the orthodontic therapy was resumed.
Radiographs and clinical examination 4 years after the completion of therapy indicates functionally and aesthetically satisfactory and stable results.
The present paper illustrates an additional application for the guided bone regeneration technique.
正畸关闭拔牙位点后牙龈内陷是一种相对常见的情况。本文报道了一例因上颌中切牙拔牙间隙正畸关闭导致严重牙龈牙槽裂患者的牙周与正畸联合治疗。
一个明确的牙间牙龈裂，延伸至牙槽骨8毫米，首先需要矫正牙龈畸形，随后进行引导性骨再生（GBR）。GBR方法包括将切牙孔清理至约5毫米深度，随后植入可吸收羟基磷灰石并用可吸收屏障膜覆盖。六个月后，恢复正畸治疗。
治疗完成4年后的X线片和临床检查表明，功能和美学效果令人满意且稳定。
本文阐述了引导性骨再生技术的一种额外应用。
