Abstract

Aim: The present systematic review and meta-analysis (SR/MA) aimed to test the null hypothesis that there is no difference between socket-shield technique (SST) and conventional immediate implant placement (CIIP) as an esthetic rehabilitation option for permanent human anterior teeth, against the alternative one of a difference. Background: Socket-shield technique is considered as a highly promising procedure that has the potential to prevent resorption of anterior alveolar ridges, maintains white and pink esthetics, and provides a solution for esthetically critical cases. Controlled randomized clinical trials (RCT) and nonrandomized ones had been identified by searching the following databases: Google Scholar, Scopus, and PubMed. Literature search was determined from January 2010 up to June 2020. Hand searches were also accomplished for relevant abstracts, books, and reference lists. The eligibility criteria included prospective observational controlled RCTs and non-RCTs. Populations: patients with endodontically treated/nonrestorable permanent mature anterior teeth indicated for extraction. Interventions: the sockets were subjected to immediate implant placement using SST. Controls: implants placed with SST compared with those of CIIP. Outcome: the pink esthetic score measured for esthetic rehabilitation. To assess article quality, the Cochrane risk-of-bias tool was used by two independent authors. The data across quantitative studies were analyzed using comprehensive MA software. Review results: The initial search found out 172 references through the search strategy and three additional ones were recognized through hand searching. After being filtered, 101 references were screened and recorded. After the inclusion and exclusion criteria were applied, only seven unduplicated prospective controlled RCTs and non-RCTs were involved in the quantitative MA. At the 6-month evaluation period, the total standard difference in mean was 1.07 and I2 test value measuring heterogeneity was 77.182, whereas at the 12-month period, the total standard difference in mean was 1.43 and I2 test value measuring heterogeneity was 64.914. Conclusion: SST had a positive effect on the esthetic rehabilitation for anterior teeth better than CIIP. However, this conclusion was dependent on a very few well-conducted prospective RCT and non-RCT. Further RCTs with longer observational time, proper methodology, and of larger sample size are still required to adequately answer the question of the present SR. Clinical significance: There is limited knowledge about the appropriateness of SST in the field of implant dentistry, specifically for esthetic consideration. This SR/MA confirmed the positive effect of the SST over CIIP for esthetic rehabilitation for anterior teeth. Systematic review registration: PROSPERO, identifier CRD42020194086.
