To evaluate the prevalence of peri-implant diseases in Spain, as well as the associated risk indicators.
This is a cross-sectional study using a network of sentinel dentists, who randomly selected 10 patients with implants (placed, at least, 5 years before), which were clinically and radiographically evaluated. Case definitions were established for peri-implant mucositis [bleeding on probing (BOP) and no bone level ≥2 mm] and peri-implantitis (BOP plus bone level ≥2 mm). Potential predictor variables, at univariate and multivariate levels, were explored by means of binary logistic regression.
A total of 49 sentinel dentists provided complete data from 474 implants in 275 patients. At implant level, prevalences for peri-implant mucositis and peri-implantitis were 27% (95% confidence interval [CI] 22-32) and 20% (95% CI: 15-24), respectively, with 17% of implants (14-21) with bone level ≥2 mm without BOP. At patient level, prevalences were 27% (22-32), 24% (19-29) and 18% (13-22), respectively. In the multiple regression analysis, statistically significant associations for peri-implantitis (p < 0.10) were found for gender, peri-implant supportive therapy, implant location, diameter and surface, type of prosthesis and access to interproximal hygiene.
In this representative subject sample across Spain, the prevalence of peri-implant diseases was high (51%).
评估西班牙种植体周围疾病的流行情况及其相关风险指标。
这是一项使用哨点牙医网络的横断面研究，他们随机选择了 10 名植入物患者（植入至少 5 年），对其进行临床和影像学评估。为种植体周围黏膜炎（探诊出血 [BOP]和无骨水平≥2mm）和种植体周围炎（BOP 加上骨水平≥2mm）建立了病例定义。通过二项逻辑回归分析，在单变量和多变量水平上探讨了潜在的预测变量。
共有 49 名哨点牙医提供了来自 275 名患者的 474 个植入物的完整数据。在植入物水平上，种植体周围黏膜炎和种植体周围炎的患病率分别为 27%（95%置信区间 [CI] 22-32）和 20%（95% CI：15-24），17%的植入物（14-21）有骨水平≥2mm而无 BOP。在患者水平上，患病率分别为 27%（22-32）、24%（19-29）和 18%（13-22）。在多变量回归分析中，性别、种植体支持性治疗、种植体位置、直径和表面、义齿类型和邻间隙卫生通道与种植体周围炎有统计学显著关联（p<0.10）。
在西班牙具有代表性的受试者样本中，种植体周围疾病的患病率很高（51%）。
