PRESENCE OR ABSENCE OF INFLAMMATION AND POOR ORAL HYGIENE IN ASSOCIATION WITH MINI IMPLANTS STABILITY: A SYSTEMATIC REVIEW AND META-ANALYSIS

Introduction: The causes of the biological instability of mini-implants are still a matter of discussion among dentistry clinicians. The aim of this systematic review and meta-analysis is to investigate inflammation of the soft tissue and poor oral hygiene as potential risk factors for mini-implant stability. Methodology: A systematic search of the literature of five major databases, PubMed, Web of Science, Science Direct, EBSCO, and Google Scholar, was carried out to include relevant and eligible literature. Results: Eight studies were included in this study, with a total of 1285 patients, and 316 of them were males. Inflammation and Poor oral hygiene were demonstrated as significant risk factors for mini-implants stability [OR, 2.37 (95% CI: 0.10, 4.65), P=0.04] and [OR, 5.7 (95% CI: 3.29, 8.1), P=0.000], respectively. Conclusion: We found that the presence of inflammation in the surrounding soft tissue of the mini-implants and poor oral hygiene are both significant risk factors for mini-implant stability.
