Aim The aim of the present systematic literature review was to evaluate bleeding on probing (BOP), pocket depth (PD), and marginal bone loss (MBL) in type 2 diabetes mellitus (T2DM) control patients. Methods An electronic literature search was conducted through PubMed, Web of Science, Cochrane, Embase, and ScienceDirect. The search included prospective human clinical studies that analyzed the success of dental implants in T2DM control patients. For inclusion, studies should have had a minimum of 1‐year follow up and should have assessed the following parameters: MBL, BOP and PD. Prior to meta‐analysis, all of the studies were assessed for quality, bias, and heterogeneity. Results Risk of bias analysis indicated that all studies were of moderate quality. After a full‐text evaluation, only seven studies met the inclusion criteria for this meta‐analysis, with a combined total of 443 patients and 530 dental implants. The meta‐analysis indicated a statistically significant difference between parameters of implants placed in the glycemic‐controlled group and healthy group in MBL (P < .001), BOP (P < .04), and PD (P < .001). Conclusion The results of the present study indicated that, despite being glycemic controlled, patients with T2DM were associated with a higher risk of peri‐implant disease.
