A Meta-Analysis Comparing Clinical Outcomes of Minimally Invasive Extraction with Immediate Implantation versus Traditional Extraction with Delayed Implantation

Objective: To compare the clinical outcomes of minimally invasive extraction with immediate implantation (MIEI) to traditional extraction with delayed implantation (TEDI) in dental procedures. Methods: A comprehensive literature search was conducted across multiple databases. Twelve randomized controlled trials involving 934 patients were included. Primary outcomes assessed were pink esthetic score (PES), white esthetic score (WES), implant success rate, patient satisfaction, and complication incidence. Standardized mean difference (SMD) and risk ratio (RR) with 95% confidence intervals (CI) were calculated using random-effects models. Results: MIEI significantly improved PES (SMD = 1.60, 95% CI: 0.87, 2.33) and WES (SMD = 2.08, 95% CI: 1.64, 2.53) compared to TEDI. No significant differences were found in implant success rates (RR = 1.00, 95% CI: 0.89, 1.14) or patient satisfaction (RR = 1.11, 95% CI: 0.94, 1.31). However, MIEI demonstrated a lower incidence of complications (RR = 0.40, 95% CI: 0.19, 0.86). Conclusions: MIEI offers superior esthetic outcomes and reduced complications compared to TEDI, while maintaining comparable success rates and patient satisfaction. These findings suggest that MIEI may be a preferable approach for suitable cases, particularly in esthetically demanding areas.
