Abstract：
Peripheral giant cell granulomas (PGCGs) are benign oral cavity tumors, reactive in nature, caused by local trauma or irritation. A 51-year-old woman presented with a soft tissue lesion related to an implant at site 36 (FDI numbering system). An excisional biopsy was completed, and the soft tissue mass was diagnosed as a PGCG. The biopsy led to a lack of keratinized tissue and vestibular depth around the implant site. After the initial healing phase, a free gingival graft was completed. Then, following soft tissue maturation, the cement-retained implant-supported prosthesis was converted into a screwretained implant-supported prosthesis that was easily accessible. With a combined periodontal and restorative approach, the KT increased, adequate vestibular depth was achieved, and there was no recurrence of the PGCG.
摘要：
周围巨细胞肉芽肿（PGCGs）是良性口腔肿瘤，反应性质，由局部创伤或刺激引起的。一名51岁的妇女在位置36（FDI编号系统）出现与植入物有关的软组织病变。切除活检完成,软组织肿块被诊断为PGCG。活检导致缺乏角化组织和植入部位周围的前庭深度。在最初的愈合阶段之后，完成了免费的牙龈移植。然后，软组织成熟后，将骨水泥保留的植入物支持的假体转换为易于使用的螺钉保留的植入物支持的假体.采用牙周和修复相结合的方法，KT增加了,达到足够的前庭深度，PGCG没有复发。
