Prevalence of peri-implantitis and peri-mucositis in pristine and augmented bone in periodontally compromised patients. A literature review.

Aim: The aim of this systematic literature review is to analyze the literature about the prevalence of peri-implantitis and peri-implant mucositis in patients with periodontal diseases and compare their prevalence in pristine and augmented sites.

Material and methods: A systematic literature review was performed of clinical trials, controlled clinical trials, comparative studies, and clinical studies. In the studies, patients who have periodontal diseases and need a dental implant with or without bone grafts were selected. Records about peri-implantitis and peri-implant mucositis, implant survival and success rates were extracted.

Results: 19 studies with 3049 patients were selected. X had a periodontal disease. After analysis, peri-implant mucositis was more prevalent in augmented sites (19% - 74.0% on patient level, 10.2% - 62,5% on implant level). Prevalence of peri-implantitis was not apparent because of missing data and heterogeneity of records. Implant survival and success rates were lower in augmented sites.

Conclusion: When alveolar ridge augmentation is needed for dental implant in patients with periodontal diseases, dentists must evaluate the risk of long term biological complications.
