牙龈瘤切除后同期使用冠向复位瓣修复大面积软组织缺损一例

牙龈瘤是一种牙龈增生性疾病, 好发于尖牙及前磨牙区唇颊侧牙龈乳头, 女性患者多于男性患者。较大的瘤体切除后常伴有角化龈变窄以及骨面、根面暴露等不良预后。该文报告在牙周黏膜科就诊的1例牙龈瘤患者, 在手术切除牙龈瘤的同时结合膜龈手术的基本原理, 使用冠向复位瓣覆盖暴露骨面及根面, 最大程度地避免感染、骨吸收、根面暴露、根面牙本质过敏症等术后并发症的发生, 并达到良好的软组织美学修复效果。就该病例的治疗过程而言, 冠向复位瓣技术具有操作简单、避免第二术区等优势。

Coverage of soft tissue defects after epulis resection with coronally repositioned flap: a case report

Epulis is a type of proliferative gingival disease, and usually occurs in the lip or buccal gingiva near the papilla canines and premolars. Females are more prone to epulis than male counterparts. The resection of large epulis is often accompanied by keratinized gingival narrowing and the exposure of bone and root surface, etc. In this article, a case of epulis admitted to the department of periodontal mucosa was reported. During surgical resection of epulis, coronally repositioned flap was simultaneously utilized to cover the exposed bone and root surface by combining the basic principle of mucogingival surgery. This technique can prevent the occurrence of postoperative complications to the largest extent, such as infection, bone absorption, root exposure and root dentin hypersensitivity, achieving excellent aesthetic repair of the soft tissues. Regarding the diagnosis and treatment of this case, the coronally repositioned flap has the advantages of simple operation and avoids the second surgical area.
