Abstract:

Objective To systematically evaluate and compare the clinical effect of immediate implant placement with socket-shield technique (SST) and conventional immediate implant (CII). Methods Databases in PubMed, Embase, Cochrane Library, Web of Science, CNKI, and Wanfang were searched to identify randomized controlled trials (RCTs) that compared SST and CII, and citation indexes were carried out for the critical pieces of literature from May 2010 to November 2021. The Cochrane Collaboration’s tool was used to assess the risk of bias. Data were analyzed using the Review Manager 5.4 software. To discuss the effects of two techniques on the clinical performance of peri-implant soft and hard tissue, implant stability quotient (ISQ), and complications and failure rate. Results A total of 14 RCTs were inclu-ded in this study, including eight in English and six in Chinese. Follow-ups ranged from 6 to 36 months, with an average of 14.21 months. Meta-analysis showed that the SST group resulted in a significantly lesser labial bone plate changes (P<0.05), stabler margin bone level (P<0.05), and better esthetic presentation (P<0.05), except for the ISQ (P>0.05). How-ever, there were no significant differences in complications and implant failure rates between the two groups (P>0.05). Conclusion In the immediate implant placement procedure, employing SST has medium- to short-term positive effects on reducing the peri-implant bone resorption and maintaining the soft tissue morphology. To supervise the current manifestation, further evidence from long-term RCTs is needed.
