The socket shield technique for immediate implant placement
Socket shield technique (SST) can reduce changes in buccal plate width and height and improve the soft tissue profile following immediate implant placement in the esthetic zone.

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.

Electronic databases were searched to identify randomized controlled trials (RCTs) that compared immediate implant placement with and without SST. 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 and height in favor of SST.

- The use of SST was also associated with significantly fewer changes in peri-implant marginal bone levels and better pink esthetic score than immediately placing implants without SST.

- The differences in implant stability, complication, and implant failure rates were not statistically significant between immediate implant placement with or without SST.

Conclusively, the short-term complication and implant failure rates following immediate implant placement with or without SST were comparable. The SST has short-term positive effects on the changes in width and height of buccal bone plate, peri-implant marginal bone levels, and esthetic outcomes.
