Stabilized oral lichen planus does not compromise dental implants survival: A systematic review and meta‐analysis.

Background: This study aimed to evaluate the incidence of implant failure in patients with oral lichen planus (OLP) and investigate the potential association between OLP and peri‐implant diseases. Materials and Methods: Embase, Web of Science, PubMed, and Scopus databases were searched for studies with no time restrictions. Meta‐analysis was performed calculating pooled proportion of peri‐implantitis (PI), peri‐implant mucositis (PIM), and bleeding on probing (BOP) prevalence using fixed‐effects model. Odds ratio and corresponding 95% CI were calculated to assess the potential risk of PI, PIM, and BOP in dental implant patients with OLP compared to healthy controls. Results: Implant failure rate was 4.38% at the patient level and 4.37% at the implant level. Six patients (3.92%) from five studies were diagnosed with oral cancer after receiving implant. The prevalence of PI, PIM, and BOP at the implant level were 14.00%, 20.00%, and 40.00%, respectively. There was no significant difference in the occurrence of PI and PIM between OLP patients and healthy controls. Conclusions: Stabilized OLP is not considered a significant risk factor for peri‐implant diseases. It is advised against placing implants or prostheses during the acute phase of the disease. Histopathological investigation to differentiate OLP from oral lichenoid dysplasia is crucial. [ABSTRACT FROM AUTHOR]
