The outcome of the osseointegrated implant is influenced by various conditions, one of which is smoking. Literature shows conflicting results for the association between smoking and implant success. Hence, the study was conducted to assess the effects of smoking on survival and marginal bone loss of osseointegrated implants. Literature search of published articles in Medline, Scopus, Ovid, and Journal of Web till June 2020 were analyzed for the determined outcomes. Revman 5.4 software was used for the analysis of the study. Of the 437 articles screened, nine were chosen for review and analysis. Meta-analytic results showed that implant success rate was better in nonsmokers than smokers (odds ratio = 0.43, 95% confidence interval = 0.26–0.72, P < 0.0001). Smoking habit does seem to affect the implant outcome of survival and marginal bone loss negatively.
