ABSTRACT Objectives Type 2 diabetes mellitus (T2DM) is a major systemic disease, predisposing patients to inflammatory conditions, and it is considered a grade modifier of periodontitis. However, its association with peri‐implant diseases is still under investigation. This study aimed to investigate the possible association between diabetes and peri‐implant disease. Material and Methods Seventy patients (35 with T2DM and 35 non‐diabetic) were included, for a total of 227 dental implants in function for at least 1 year. Patient characteristics, implant features, and peri‐implant diseases (including peri‐implant mucositis and peri‐implantitis) were recorded. Results The overall prevalence of peri‐implant diseases was not statistically different between diabetic and non‐diabetic subjects (80% vs. 77%, p = 0.99). When distinguishing between peri‐implant mucositis and peri‐implantitis, the prevalence of peri‐implant mucositis (51% in diabetic patients vs. 63% in non‐diabetic individuals; p = 0.47) and peri‐implantitis (51% in diabetic patients vs. 43% in non‐diabetic individuals; p = 0.63) did not differ significantly between the two groups. Conclusions Our findings did not suggest different occurrence of peri‐implant mucositis and peri‐implantitis in diabetic and non‐diabetic subjects. Therefore, type 2 diabetes may not play a relevant role in peri‐implant diseases.
