The purpose of the present review was to integrate the available published data on peripheral giant cell granuloma (PGCG) associated with dental implants into a comprehensive analysis of its clinical/radiologic features. An electronic search was undertaken in February/2018 in three databases, looking for publications reporting cases of PGCGs associated with dental implants. Nineteen publications were included, reporting 37 implant-associated PGCG. These lesions are more prevalent in women, in mandible, and in posterior regions of the jaws. Both 'excision alone' and 'excision + curettage' presented high recurrence rates (40% and 31.3%, respectively). The etiology of implant-associated PGCG has not yet been determined. Despite the small number of cases reported, implant-associated PGCG shows a high recurrence rate (1/3) for a benign non-neoplastic lesion and sometimes it requires the removal of the associated implant in order to prevent further recurrences. This recurrence rate is not affected by curettage after excision.
本次综述的目的是将有关与牙种植体相关的外周性巨细胞肉芽肿(PGCG)的现有发表数据整合到对其临床/放射学特征的综合分析中。2018 年 2 月,我们在三个数据库中进行了电子检索,以寻找报告与牙种植体相关的 PGCG 病例的出版物。共纳入 19 项研究,报道了 37 例与种植体相关的 PGCG。这些病变在女性、下颌骨和颌骨后区更为常见。单纯切除和切除+刮除的复发率均较高(分别为 40%和 31.3%)。与种植体相关的 PGCG 的病因尚未确定。尽管报告的病例数量较少,但与种植体相关的 PGCG 作为良性非肿瘤性病变具有较高的复发率(1/3),有时需要切除相关种植体以防止进一步复发。这种复发率不受切除后刮除的影响。
