Efficacy of Vertical Soft Tissue Augmentation Techniques and their Influence on Marginal Bone Loss Around Dental Implants: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis comparing vertical soft tissue augmentation techniques for dental implants found that while the tent-pole technique (TPT) and matrix-based grafts (MB) demonstrated the greatest supracrestal tissue height gains and minimal marginal bone loss, no statistically significant differences were observed between methods due to high heterogeneity and methodological limitations in the current evidence.
