Objective The aim of the present systematic review and meta‐analysis was to assess the role of periodontal disease as a risk factor for implant loss, peri‐implantitis and implant‐bone loss. Materials and methods Six electronic database and a manual search resulted in 7391 unique publications; after selection only 16 studies were included in systematic review. Dichotomous data were expressed as risk ratio ( RR ) and 95% confidence interval ( CI ), while continuous data were expressed as standardized mean difference ( SMD ). Due to the expected inter‐study heterogeneity, a random effect model was used for both type of data. The pooled effect was considered significant for a P < 0.05. Results Meta‐analysis revealed that an higher and significant risk for implant loss was present in patients affected by PD ( RR : 1.69, 95% CI : 1.31–2.17, P < 0.0001). A higher and significant IBL was present in patients with periodontal disease, when compared with patients periodontally healthy ( SMD : 0.38, 95% CI : 0.18–0.58, P = 0.0002). Patients periodontally compromised showed an increased risk of PI , when compared with patients without periodontitis ( RR : 2.17, 95% CI : 1.51–3.12, P < 0.0001) No evidence of significant heterogeneity was detected for the three outcomes. Conclusion Strong evidence suggests that periodontitis is a risk factor for implant loss; moderate evidence revealed that periodontitis is a risk factor for peri‐implantitis and that patients with periodontitis have higher implant‐bone loss.
