Risk for recurrence of disease following surgical therapy of peri‐implantitis—A prospective longitudinal study

OBJECTIVES: The aim of the present prospective study was to assess the risk for disease recurrence following surgical therapy of peri-implantitis. MATERIAL 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.
