Abstract
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.
