Bone Augmentation with Fibrin Sealant during Guided Bone Regeneration for Implant Surgery

The idea of using a fibrin sealant in the augmentation of the alveolar ridge defects seems attractive because it can produce a dense fibrin clot with sufficient adhesive strength to hold particulate bone in a required configuration. The aim of this clinical investigation is to evaluate the possibility of obtaining bone augmentation around osseointegrated implants by using fibrin sealing system with grafting material. Buccal and lingual local anesthesia was injected. A lingual crestal incision was made connecting the edentulous space. Vertical buccal releasing incisions were performed. A full-thickness flap was then elevated until the mucogingival junction to achieve a tension-free adaptation of the soft tissues. The defects were filled with granules of allograft and alloplast mixed with a fibrin-fibronectin sealing system. Seven-months after surgery, implants were inserted in a prosthetically driven position. At 2nd surgery, a hard bone like tissue was detectable at the defect sites receiving allograft bone grafts with a fibrin-fibronectin sealing system and well maintained. Clinical cases show that the vertical alveolar bone height is well-maintained after alveolar bone augmentation using fibrin sealant because of its sufficient adhesive strength to hold particulate bone in a required configuration.
