Prevalence of Peri-implant Diseases – Part 1

Aim: Determine the prevalence of peri-implant diseases; mucositis and periodontitis, of patients from the Center of Studies of Continuing Education in Implant Dentistry of the Federal University of Santa Catarina.In addition to the extension of the disease, the proportion of affected implants was studied. Materials and Methods:A cross-sectional study was carried out in 200 patients presenting 760 external-hexed cylindrical dental implant supported prosthesis with at least 1 year of loading time (range: 1-9 years).Probing depth, bleeding on probing and suppuration data was collected.Radiographs were required to evaluate supporting bone levels around implants.Results: One hundred and thirty-nine (69%) patients presented all healthy implants, 46 (23%) patients presented peri-implant mucositis and 15 (8%) presented peri-implantitis.The overall outcome was 547 (72%) healthy implants, 161(21%) with peri-implant mucostitis and 62 (7%) with peri-implantitis. Conclusion:According to the results, it is concluded that the prevalence of peri-implant mucositis was 23% and peri-implantitis to 8%. Clinical RelevanceScientific rationale for study: The prevalence of peri-implant diseases has not yet been presented with absolute values due to insufficient studies [1].Principal findings: The peri-implant mucositis prevalence in this study was significantly lower than the results presented in the literature.However, peri-implantitis prevalence concurs and other time diverges with the literature.Practical implications: Excessive force applied in the BOP exam could have resulted in false positive findings for the peri-implant diseases.Care is necessary to adequately diagnose the disease.
