Bone reconstruction is sometimes necessary before the implant placement. As a result, various clinical procedures such as Plasma Rich in Growth Factors (PRGF) have been described for preserving or increasing bone volume. We present here six patients, mean age of 58.2 years ± 8.9, with volumetric bone defects on the maxilla that have been treated using PRGF protocol in oral implantology. A CBCT was prescribed before and after the surgery. Measurements of the ridge was divided into 3/3 from the top to its base. On the day of surgery, the patient's venous blood is collected, and placed in a System V® centrifuge, allowing the platelets to be separated in Fraction 1 (F1) rich in fibrin, and Fraction 2 (F2) rich in platelets. After the removal of the stitches 2 to 3 days after surgery. Mean residual crestal width was 3.7 mm ± 0.8 (range: 3 mm to 5 mm), mean residual vestibular height was 6.2 mm ± 2.9 (3 mm to 11 mm) and mean residual palatal height was 8.7 mm ± 2.1 (6 mm to 11 mm). An average of 5 implants per patients (1 to 8) have been placed. At six months follow-up, the average height gain was 5.7 mm ± 2.1 (2 to 8) for the vestibular wall and 3.3 mm ± 1.2 (2 to 5) for the palatine wall. The average gain in crestal width was 4.2 mm ± 0.8 (3 to 5). PRGF form mixed with a filling allograft biomaterial, and a membrane resulting from the same PRGF protocol, represents a promising treatment of bone defects in implantology.
