Abstract
The purposes of this study is to evaluate the prevalence of peri-implant diseases; mucositis and peri-implantitis of patients received dental implant at Riyadh city, KSA. In addition to the assessment of the relationship between peri-implant diseases and other related risk factors such as plaque accumulation, smoking, diabetes, and overall periodontal condition. A cross-sectional study was carried out for 67 patients who had 188 dental implant supported prosthesis with at least 1 year of loading time (range: 1–9 years). Modified plaque index (mPI), modified gingival index (mGI), probing depth, bleeding on probing, suppuration and mobility data were collected. Radiographs were required to evaluate supporting bone levels around implants with severe inflammatory signs. Findings revealed that on patients level (30%) of cases were with healthy implants, (43%) of cases were with peri-implant mucositis and (27%) with peri-implantitis. The overall outcome on implant level was (27%) healthy implants, (51%) with peri-implant mucostitis and (22%) with peri-implantitis. Highly statistic significance association was found between healthy periodontium and healthy peri-implant tissue status. Patients with a history of periodontitis and active periodontal disease were more prone to develop peri-implant diseases. Plaque accumulation around dental implants, function time, increased number of placed implants, implant supported by full arch fixed denture and overdentures were the most involved risk factors.
