The aim of this study was to assess the clinical outcomes of a nonsurgical treatment protocol for peri-implantitis and to evaluate the influence that some factors could have on the results of this treatment.
In this retrospective case series, patients with at least one implant with peri-implantitis, treated with a nonsurgical protocol and with a one-year follow-up, were included. Clinical parameters (probing depth, recession, bleeding, and/or suppuration on probing) were collected at baseline, 6 weeks, 3, 6, and 12 months. Radiographic bone levels were assessed in periapical radiographs taken at baseline and 12 months. An analysis of the factors significantly associated with marginal bone level changes was performed. Descriptive and analytic statistics were carried out at the patient and at the implant level, as well as a multiple linear regression analysis.
Data from 37 patients with 70 implants were analyzed. There was a general and consistent improvement from baseline compared to all follow-up points in the clinical variables. A significant radiographic bone gain of 0.91 mm was observed. The factors significantly associated were baseline plaque index, sex, and age at patient level, and type of prosthesis and implant location at implant level.
Within the limitations of this study, this nonsurgical treatment protocol might be considered as a first treatment option for peri-implantitis. More studies are needed, with larger sample sizes and longer follow-ups, to confirm these outcomes and their long-term stability.
本研究旨在评估一种针对种植体周围炎的非手术治疗方案的临床效果，并评估某些因素对该治疗结果的影响。
在这项回顾性病例系列研究中，纳入了接受非手术方案治疗且有一年随访期的至少有一个种植体周围炎种植体的患者。在基线、6 周、3、6 和 12 个月时采集临床参数（探诊深度、退缩、出血和/或探诊溢脓）。在基线和 12 个月时拍摄根尖片评估放射影像学骨水平。对与边缘骨水平变化显著相关的因素进行了分析。在患者和种植体水平进行了描述性和分析性统计分析，以及多元线性回归分析。
对 37 名患者的 70 个种植体的数据进行了分析。与所有随访点相比，临床变量均从基线开始出现总体且一致的改善。观察到放射影像学骨水平有显著的 0.91mm 的获得。在患者水平上，与边缘骨水平变化显著相关的因素是基线菌斑指数、性别和年龄，而在种植体水平上，与边缘骨水平变化显著相关的因素是修复体类型和种植体位置。
在本研究的限制范围内，这种非手术治疗方案可被视为种植体周围炎的首选初始治疗方案。需要更多的研究，样本量更大且随访时间更长，以确认这些结果及其长期稳定性。
