Soft Tissue Augmentation Around Dental Implants: Techniques, Timing, and Comparative Efficacy—A Systematic Review and Network Meta‐Analysis

APF + FGG is the most reliable approach for increasing KTW, while CTG remains the gold standard for MT enhancement. The choice of technique and graft material appears more critical than surgical timing. Long-term stability of tissue dimensions and standardization of reporting across future trials are essential to refine clinical decision-making in STA procedures.
