The aim of this study was to report 2 novel clinical cases of reactive lesions of the peri-implant mucosa associated with titanium dental implants where metal-like particles were observed histologically. In both cases, the lesions were diagnosed as epulis, based on clinical evidence. Extirpation biopsies were carried out. Case 1 was diagnosed as pyogenic granuloma and case 2 as peripheral giant cell granuloma. The presence of metal-like particles in the tissues suggests that the etiology of the lesions might be related to the corrosion process of the metal structure. This is the first case of pyogenic granuloma to be reported in association with dental implants. All clinical cases of soft tissue lesions associated with implants should be reported to contribute to the understanding of the etiology and pathogeny of these lesions.
本研究旨在报告 2 例与钛种植体相关的种植体周围黏膜反应性病变的新临床病例，其中组织学观察到类似金属的颗粒。在这两种情况下，根据临床证据，病变均被诊断为龈瘤。进行了切除活检。病例 1 被诊断为化脓性肉芽肿，病例 2 被诊断为外周性巨细胞肉芽肿。组织中类似金属的颗粒的存在表明，病变的病因可能与金属结构的腐蚀过程有关。这是首例与牙种植体相关的化脓性肉芽肿报道。所有与植入物相关的软组织病变的临床病例都应报告，以有助于了解这些病变的病因和发病机制。
