An Innovative Microsuturing Technique for Stabilization of a Free Gingival Graft: The 'Fishnet Suture'

Area of Science:

• Periodontology
• Oral Surgery

Background:

• Free gingival graft (FGG) stability is crucial for successful outcomes.
• Micro-movements can compromise graft healing and vascular integration.

Purpose of the Study:

• To introduce and evaluate the 'Fishnet suture,' a novel microsuturing technique for enhanced free gingival graft stabilization.
• To assess the efficacy of the Fishnet suture in promoting graft vascularization and predictable soft tissue augmentation.

Main Methods:

• A novel 'Fishnet suture' technique using continuous interlocking vertical and horizontal components was developed.
• The technique was applied in three distinct clinical scenarios: gingival recession, peri-implant defects, and keratinized tissue augmentation.
• Graft stabilization, tension distribution, and elimination of dead spaces were key procedural focuses.

Main Results:

• The Fishnet suture technique demonstrated effective graft stabilization and uniform tension distribution.
• Postoperative healing was uneventful across all three clinical cases.
• Significant increases in keratinized tissue width were observed, indicating successful soft tissue augmentation.

Conclusions:

• The novel Fishnet suture technique offers a promising approach for superior free gingival graft stabilization.
• This method facilitates enhanced graft adaptation, reduces micro-movements, and promotes optimal revascularization and clinical outcomes.
• The technique is applicable to various reconstructive needs in periodontology and implant dentistry.
