摘要：

牙周炎患者在接受种植治疗时面临较高风险，主要为种植体存活率低、种植体周炎发生率高且进展迅速。同时，牙周炎患者常伴有不同程度的软、硬组织缺损，进一步增加了种植治疗的复杂性。慢性炎症状态和口腔微生物群失衡被认为是影响种植治疗预后的重要因素。因此，在实施种植之前，应充分控制牙周炎及相关系统性疾病，并选择合适的种植体和手术时机。术后良好的口腔卫生管理、定期随访及支持性牙周治疗，对降低种植体周疾病发生风险，提高种植体长期成功率具有重要意义。尽管牙周炎患者接受种植治疗时会面临较多挑战，但通过综合治疗和精细管理，仍然能取得较好的临床效果。

Abstract:

Patients with periodontitis are confronted with elevated risks during implant therapy, mainly manifested as a lower implant survival rate, as well as a higher incidence and faster progression of peri-implantitis. Meanwhile, patients with periodontitis frequently present with varying degrees of soft and hard tissue defects, which further increase the complexity of implant therapy. Chronic inflammation status and oral microbiota dysbiosis are recognized as critical factors affecting the prognosis of implant therapy. Therefore, prior to implant placement, periodontitis and associated systemic diseases should be adequately controlled, and appropriate implant types as well as optimal surgical timing should be selected. Good postoperative oral hygiene management, regular follow-up and supportive periodontal therapy are of great significance for reducing the risk of peri-implant diseases and improving the long-term success rate of implants. Although patients with periodontitis face considerable challenges when undergoing implant therapy, favorable clinical outcomes can still be achieved through comprehensive treatment and meticulous management.
