Fibrinogen-Induced Regeneration Sealing Technique (F.I.R.S.T.). An Improvement and Modification of Traditional GBR: A Report of Two Cases
Guided bone regeneration is a technique widely known, clinicians know very well indications and
limitations of this technique. One of the principles to achieve bone augmentation and formation resides
in the stability of the blood clot forming under a barrier membrane. The technique proposed in this article
has the goal of providing stabilization to the bone graft by adding fibrin sealant (FS) to the bone graft and
also using the fibrin sealant to attach a bone membrane (cortical lamina) to the recipient site. This simple
modification of the technique of guided bone regeneration is presented in two successful cases.
