Figures & data
Figure 1. Concentrated growth factors.
(A) Three blood fractions were obtained through centrifuge process (1) a superior phase represented by the serum; (2) an interim phase represented by a very large and dense polymerized fibrin block containing the CGFs, white blood cells and stem cells; and (3) the lower red blood cell layer. (B) CGFs separated from platelet-poor plasma.
Figure 2. (A) An example in the experimental group: the second right mandibular premolar, baseline. (B) Intra-surgical findings. (C) Mixture of CGFs and BPBM granules was placed into the defect. (D) CGFs membrane was placed. (E) Flap sutured. (F) 1 year post-surgery.

AC: Alveolar crest; BD: Base of the defect; CEJ: Cemento–enamel junction.
