Buccal Bone Thickness and Mid-facial Soft Tissue Recession after Various Surgical Approaches for Immediate Implant Placement: A Systematic Review and Network Meta-analysis of Controlled Trials.

For immediate implant placement in the anterior areas, a FL-HTA approach better preserves buccal bone thickness (moderate confidence); adding STA improves the stability of the mid-facial soft tissue level (moderate confidence) but at the expense of buccal bone thickness (low confidence).
