Roos‐Jansåker A‐M, Lindahl C, Persson GR, Renvert S. Long‐term stability of surgical bone regenerative procedures of peri‐implantitis lesions in a prospective case‐control study over 3 years. J Clin Periodontol 2011; doi: 10.1111/j.1600‐051X.2011.01729.x. Abstract Objectives: To evaluate the extent of bone fill over 3 years following the surgical treatment of peri‐implantitis with bone grafting with or without a membrane. Material and Methods: In a non‐submerged wound‐healing mode, 15 subjects with 27 implants were treated with a bone substitute (Algipore ® ) alone and 17 subjects with 29 implants were treated with the bone substitute and a resorbable membrane (Osseoquest ® ). Implants with radiographic bone loss ≥1.8 mm following the first year in function and with bleeding and/or pus on probing were included. Following surgery, subjects were given systemic antibiotics (10 days) and rinsed with chlorhexidine. After initial healing, the subjects were enrolled in a strict maintenance programme. Results: Statistical analysis failed to demonstrate changes in bone fill between 1 and 3 years both between and within procedure groups. The mean defect fill at 3 years was 1.3 ± (SD) 1.3 mm if treated with the bone substitute alone and 1.6 ± (SD) 1.2 mm if treated with an adjunct resorbable membrane, ( p =0.40). The plaque index decreased from approximately 40–10%, remaining stable during the following 2 years. Conclusion: Defect fill using a bone substitute with or without a membrane technique in the treatment of peri‐implantitis can be maintained over 3 years.
