Before the procedure, a small amount of blood is collected from the upper limb and prepared in a special centrifuge. Fibrin plugs are formed from the blood, inserted into the extraction wound and sutured. The plugs are rich in fibrin, leukocytes, platelets and growth factors that are released from the plug in the days after extraction and make healing faster and more efficient. Tissue regeneration is better and faster. The volume of bone that regenerates with the use of a fibrin plug is significantly larger than without its use. Bone deficiency is in many cases a limiting factor in implant therapy that follows.
