Objectives The aim of the present prospective study was to assess the risk for disease recurrence following surgical therapy of peri‐implantitis. Material & Methods 73 patients (130 implants) treated surgically for peri‐implantitis were examined at 1 and 5 years after therapy. The primary outcome was recurrence/progression of disease defined as any of the following events: (a) bone loss >1.0 mm, (b) surgical retreatment, (c) implant removal/loss after year 1. Patient‐ and implant‐related parameters as well as 1‐year outcomes were evaluated as potential predictors through multiple logistic regression analysis. Results 57 implants (44%) displayed recurrence/progression of peri‐implantitis during follow‐up. Among these, 27 implants were removed. Residual deep probing pocket depth (≥6 mm; odds ratio 7.4; 95% confidence interval 2.8–19.3) and reduced marginal bone level (OR 1.4; 95%CI 1.1–1.7) at 1 year after surgery constituted risk factors for recurrence/progression of disease. Furthermore, implants with modified surfaces were at higher risk than implants with non‐modified surfaces (OR 5.1; 95%CI 1.6–16.5). Conclusion Implants with (a) residual deep probing pocket depth, (b) reduced marginal bone level, or (c) modified surfaces following surgical therapy of peri‐implantitis present with increased risk for recurrence/progression.
