Title : The use of buccal free fat tissue graft to enhance primary soft tissue closure during socket preservation and ridge contour improvement at the extraction sites
Objectives: The aim of this presentation to share a new technique utilizing the buccal free fat tissue graft (BFFG) harvested from the buccal fat pad (BFP) for socket preservation, allowing primary closure and socket seal at the extraction site.
Materials and Methods: Twelve patients (9 women, 3 men; mean age 37) with 28 extraction sites were treated using BFFG for socket preservation and followed-up over 12-60 months post operatively. Ten patients received 22 implants in 25 treated sockets, and 2 patients were treated by conventional fixed partial denture over 3 treated sockets. BFFG was placed covering different bone grafting material in fresh extraction sockets without the use of membrane. Patients were examined clinically and radiographically at 2, 4weeks, 2- and 4-months post operatively. At 4 months computed tomography was performed to evaluate soft and osseous tissues dimensions of the treated sites. Implant placement was performed 4-5 months post operatively.
Results: Following BFFG grafting, healing was uneventful, with minimal morbidity. Follow- up revealed that socket volume was preserved when compared to the original dimension prior extraction. Soft tissue healing showed perfect color match with the surrounding tissue.
Conclusions: Harvesting of BFFG from BFP is a simple procedure with minor complications that might be used to enhance primary soft tissue closure of an extraction site. This technique allows improvement and maintaining long-term ridge contour and soft tissue thickness, and blends in the neighboring attached gingiva.
