AimTo evaluate the effectiveness of a flapless surgical approach in the treatment of peri‐implantitis and to explore the factors influencing its outcome.Materials and MethodsThe present retrospective study evaluated patients with at least one implant diagnosed with peri‐implantitis and treated with a flapless surgical access, with or without systemic antimicrobials, curettage and, when needed, prostheses modification. Clinical and radiographic parameters were assessed at baseline and at 3 months and at least 12 months. The primary outcome was disease resolution (≤1 bleeding sites, probing depth [PD] ≤5 mm, no bone loss >0.5 mm). Multilevel regression analyses were used to identify predictors influencing the probability of attaining disease resolution.ResultsOne hundred and seventeen patients with 338 implants were included. Disease resolution was attained in 54.4% of the 338 implants receiving flapless surgical access. At the end of the follow‐up period, 111 patients (94.9%) with 295 implants (87.3%) did not require any further treatment, with 81.4% of these implants presenting PD ≤ 5 mm. History of periodontitis and PD at baseline were identified as negative predictors, while compliance with supportive peri‐implant care, a machined surface and the adjunctive use of systemic azithromycin or metronidazole were identified as positive predictive factors for disease resolution.ConclusionsA flapless surgical approach led to disease resolution in 54.4% of the implants with peri‐implantitis. Several risk/protective predictors for disease resolution were identified.

无翻瓣手术通路联合种植体表面去污和辅助全身性抗生素治疗种植体周围炎：一项回顾性病例系列研究


目的评价无翻瓣手术方法治疗种植体周围炎的有效性，并探讨影响其结局的因素。材料和方法本回顾性研究评估了至少一个种植体被诊断为种植体周围炎并接受无翻瓣手术通路治疗的患者，有或没有全身抗菌剂、刮除术，并在需要时进行修复体修改。在基线和 3 个月和至少 12 个月时评估临床和影像学参数。主要结局是疾病消退 （≤1 个出血部位，探诊深度 [PD] ≤5 mm，无骨质流失 >0.5 mm）。多水平回归分析用于确定影响疾病消退概率的预测因子。结果纳入 117 例患者，植入 338 例。在接受无瓣手术通路的 54.4 个种植体中，有 338% 实现了疾病消退。在随访期结束时，111 名患者 （94.9%） 和 295 个植入物 （87.3%） 不需要任何进一步治疗，其中 81.4% 的植入物出现 PD ≤ 5 毫米。基线时牙周炎病史和 PD 被确定为阴性预测因素，而对支持性种植体周围护理、机械表面和辅助使用全身性阿奇霉素或甲硝唑的依从性被确定为疾病缓解的阳性预测因素。结论无翻瓣手术方法导致 54.4% 的种植体周围炎植入物疾病消退。确定了疾病消退的几个风险/保护性预测因子。
