The socket shield technique for immediate implant placement: A systematic review and meta‐analysis

BACKGROUND Immediate implant placement with socket shield technique (SST) may maintain the buccal bone plate and soft tissue levels, however, the potential clinical benefits of SST lack strong scientific evidence. The aim of this systematic review and meta-analysis was to evaluate the effects of SST on dimensional changes of hard tissues, esthetic outcomes, implant stability, complication, and implant failure rates. METHODS Electronic databases were searched to identify randomized controlled trials (RCTs) that compared immediate implant placement with and without SST. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. Data were analyzed using a statistical software program. RESULTS A total of 982 studies were identified, of which, seven RCTs with 206 immediately placed dental implants in 191 participants were included. Overall meta-analysis showed significant differences in the changes in buccal bone plate width (mean difference (MD) -0.22; 95% confidence interval (CI) -0.30 to -0.15; p
