Effectiveness of implant‐supported fixed partial denture in patients with history of periodontitis: A systematic review and meta‐analysis

Abstract Aim This systematic review investigates the effectiveness of implant‐supported fixed partial denture (IS‐FPD) in patients with history of periodontitis (HP) vs. patients with no history of periodontitis (NHP). Methods A literature search was performed on different databases on May 2020. Prospective and retrospective studies assessing survival (primary outcome), success and biological/mechanical complications of IS‐FPDs in HP vs. NHP patients at ≥1 year after implant loading were evaluated. Meta‐analyses were conducted by estimating hazard ratio (HR), risk ratio (RR) and standardized mean differences (SMD) with 95% confidence intervals (CI) using random effect models. Results Of the initially identified 4096 articles, 349 underwent a full‐text evaluation. Finally, 17 were included. Pooled data analyses showed that overall implant survival was significantly higher in the NHP than the HP group (HR = 2.06; 95% CI = 1.37–3.09; I 2 = 0%). This difference was noted when follow‐up ≥5 years. The risk of peri‐implantitis was higher in HP than NHP patients (RR = 3.3; 95% CI = 1.31–8.3; I 2 = 0%), whereas the mean marginal bone level change over time was not different between the groups (SMD = −0.16 mm; 95% CI = −1.04–0.73; I 2 = 98%). Conclusions In partially edentulous patients receiving IS‐FPDs, a history of periodontitis is associated with poorer survival rate and higher risk of peri‐implantitis during a 5–10 years period after implant loading.
