To evaluate the clinical and radiographic short-term (6 months) effect of surgical treatment of peri-implantitis, and to identify prognostic indicators affecting the outcome using a multilevel statistical model.
MATERIALS & METHODS: A total of 143 implants (45 patients) with a diagnosis of progressive peri-implantitis (progressive bone loss (PBL) ≥2.0 mm and bleeding on probing (BoP)/suppuration) received surgical treatment. Clinical and radiographic parameters were assessed 6 months postoperatively. Potential prognostic indicators on subject, implant and site level prior to surgery were analysed to evaluate the effect on individual and composite outcomes using multilevel logistic regression analysis.
At the 6-month evaluation, none of the implants demonstrated PBL and 14% of the implants were registered with the absence of bleeding and no pocket probing depth ≥6 mm. Multilevel regression analysis identified, among others, suppuration, pocket probing depth >8 mm, bone loss >7 mm and the presence of plaque as criteria associated with the outcome.
Resective peri-implantitis surgery seemed to reduce the amount of peri-implant inflammation. However, most of the sites continued to have BoP/suppuration. Thus, long-term maintenance and evaluation is warranted. The effect of treatment was reduced by some prognostic indicators such as the presence of suppuration prior to interception and peri-implant bone loss exceeding 7 mm.
评估种植体周围炎的手术治疗短期（6 个月）临床和影像学效果，并使用多水平统计模型确定影响治疗效果的预后指标。
共 45 名患者的 143 个种植体（45 名患者）诊断为进行性种植体周围炎（进展性骨丧失（PBL）≥2.0mm 和探诊出血/溢脓），接受了手术治疗。术后 6 个月评估临床和影像学参数。在术前对患者、种植体和部位水平的潜在预后指标进行分析，使用多水平逻辑回归分析评估对个体和综合结果的影响。
在 6 个月的评估中，没有一个种植体显示 PBL，14%的种植体没有出血和探诊深度≥6mm 的溢脓。多水平回归分析确定，除其他外，溢脓、探诊深度>8mm、骨丧失>7mm 和有菌斑是与结果相关的标准。
切除性种植体周围炎手术似乎减少了种植体周围的炎症程度。然而，大多数部位仍有探诊出血/溢脓。因此，需要长期的维护和评估。一些预后指标如术前存在溢脓和种植体周围骨丧失超过 7mm，会降低治疗效果。
