The Flap Folding Suture (FFS), developed by Prof. Jung-Chul Park (Dankook University), is a specialized periodontal suturing technique designed to maximize keratinized tissue and stabilize soft tissue volume around dental implants. [1, 2, 3, 4, 5]

Core Purpose & Benefits

• Prevents Soft Tissue Migration: Traditional interrupted sutures often fail to stabilize the tissue properly, causing the gums to "climb" up the healing abutment. This can lead to soft tissue volume loss, necrosis, and diminished keratinized tissue. [1]

• Maximizes Keratinized Gingiva: The FFS technique securely folds and positions the flap to prevent this migration, preserving and thickening the attached gingiva. [1, 2, 3, 4, 5]

• Improved Healing Dynamics: 3D digital analyses of clinical cases show that FFS significantly improves soft-tissue volume maintenance around the implant site compared to conventional sutures. [1]

Technique & Usage

During implant uncovery or placement, the paramarginal flap is folded and secured internally. This helps retain the structural integrity of the mucosa and avoids the need for more invasive procedures like free gingival grafts (FGG). [1, 2, 3, 4]

You can explore detailed clinical steps and surgical demonstrations of this technique directly through Prof. JC Park's Back to the Suture Channel or browse his educational implant resources on eDental Supply. Academic data and 3D volumetric analysis regarding the effectiveness of the flap folding suture are also available via KoreaMed. [1]
