5. Platelet Rich Plasma –PRP
is obtained by sequestering and concentrating platelets by gradient density centrifugation Platelet Rich Plasma Gel
6. Platelet rich plasma gel is an autologous modification of fibrin glue made by mixing platelets and fibrinogen centrifuged from whole blood with thrombin and calcium chloride. Increase platelet concentration in wound by more than 300 percent.
10. Platelet enriched plasma
Autologous thrombin

52. Genetically engineered human Bone Morphogenetic Proteins increase the amount and purity . Osteogenin is another name for B.M. P. Most osteogenins are bound to a carrier of bovine type I collagen sponge or other carrier.
60. Got good bone in cores
One patient had mucus retention cyst on CT at 16 weeks
Got mean bone height increase of 8.51 mm to 15.73 mm
8 to 11 patients had sufficient bone for implant placement.
2 biopsies at 19 weeks had moderate amount of bone
10 biopsies at 24 to 27 weeks had moderate to large amounts of bone.
61. This Bovine protein extract (Neo osteo, Sulzer) contained Bone Morphogenetic Proteins 2, 3, 4, 6, 7, 12, 13.
