Correlation between Diabetes Mellitus and Peri-implantitis: A Systematic Review

Abstract

Background: Osseo-integrated implants provide effective treatment results for edentulous patients. However, despite the high success and survival rates of dental implants, several factors, such as poor oral hygiene and a history of periodontal disease, and systemic diseases, such as diabetes mellitus, could influence the outcome of the treatment. In fact, poor glycemic control can affect the healing process. Diabetes mellitus is considered a relative contraindication for dental implant therapy due to the fact that the success rates of the implants seem to be lower in diabetic patients, even if there is no total agreement among the results reported in the literature. The analysis of peri-implant inflammation indices, bone loss around the implant and glycemic index can provide us with useful information on the relationship between glycaemia in diabetic patients and the course of peri-implantitis, as well as implant success in the short term.

Objective: The purpose of this review is to establish how peri-implant inflammation parameters vary in diabetic versus non-diabetic patients.

Methods: This review was conducted on the basis of PRISMA. The search was conducted by three independent reviewers searching for keywords in three databases: PubMed, Scopus, Web Of Sciences (WOS), and the Cochrane Central Register of Controlled Trial.

Results: A total of 1159 records were identified, and 11 articles were included in the qualitative analysis.

Conclusion: The analysis of the extracted data from the included studies suggests that some periimplant inflammation indices, such as bleeding on probing and bone loss around the implant, appear to be increased in diabetic patients with glycometabolic decompensation, compared with control not affected by diabetes mellitus.

Keywords: Diabetes mellitus; PRISMA; dental implants; glycemic index; glycometabolic decompensation; peri-implantitis.
