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%).
