Clinical Trial Summary

The primary objective of this controlled clinical trial is to evaluate the clinical effect of systemic amoxicillin plus metronidazole therapy in conjunction with initial non-surgical treatment of peri-implantitis. The secondary objective is to assess the microbiological effectiveness of this peri-implantitis treatment approach. The present study is a single-blind, randomized controlled clinical trial. Adult patients with at least one endosseous implant in the oral cavity with clinical and radiographical evidence of periimplantitis will be included in this study. Patients with implants affected by peri-implantitis will receive initial periodontal treatment existing of oral hygiene instructions and mechanical cleansing of both implants and remaining dentition. Immediately after initial periodontal therapy patients will be instructed to rinse their mouth with 0.12% chlorhexidine + 0.05% cetylpyridinium chloride without alcohol twice daily during 30 seconds for 2 weeks. Additionally patients will receive a recipe for medication consisting of 500 mg amoxicillin and 500 mg metronidazole to be taken every 8 hours for the following 7 days or no recipe. The main study parameter is the mean peri-implant bleeding score.
