  59. 59. Growth factors Forms Recombinant human Growth Factor
  60. 60. Types of growth factors • Fibroblast Growth Factor (FGF): - chemo-attractants for endothelial cells as well as for a variety of mesenchymal cells including: fibroblasts, osteoblasts, chondrocytes, skeletal myoblasts and smooth muscle cells. • Insulin-like Growth Factors (IGFs): - increase DNA synthesis in osteoblastsand stimulated the formation of bone matrix
  61. 61. • Platelet- derived Growth Factors (PDGF): - chemoattractant for fibroblasts and inflammatory cells and in addition it stimulates production of matrix components. • Transforming Growth Factor (TGF): -have been shown to affect bone metabolism through modulation of both osteoclastic and osteoblastic cell differentiation and activity. •Bone morphogenic proteins (BMPs): -multi-functionalgrowth factors. -periodontal regeneration. •Epithelial Growth Factor (EGF): -promote re-epithelialization andwound healing.
  62. 62. •The active component of INFUSE Bone Graft - rhBMP-2- is a recombinantly- produced form of a signaling protein naturally occurring in the human body. •Mesenchymal stem cells proliferate, or increase rapidly in number, at the site due to Presence of rhBMP-2, supported by increased angiogenesis at the site.
  63. 63. INFUSE Bone Graft: received approval for use in sinus augmentation and for localized ridge augmentation for defects associated with extraction sockets. 1965: Dr. Marshall R. Urist discovers That demineralized bone matrix stimulates the formation of new bone tissue in lower-order animal muscle. This led to : The isolation of bone morphogenetic proteins (BMPs), the only proteins known to induce new bone formation(osteoinduction). 2002: INFUSE Bone Graft : received approval for use in anterior lumbar spine fusion with Medtronic titanium threaded interbody devices. 2004: INFUSE Bone Graft: received approval for use in open tibial fractures with intramedullary (IM) nail fixation. 2007:
  64. 64. •Reasons to consider INFUSE Bone Graft: •Eliminates the need for a second bone harvest surgery. •Regenerates 100% vital, vascular de novo bone with no residual graft material remaining to destabilize bone formation. • complex augmentation cases. •Supported by over 20 years of research and clinical results, including 60 preclinical studies and 5 clinical trials.
  65. 65. •Important Information about INFUSE® Bone Graft: •The potential for prolonged swelling may occur in some (but not all) patients. This is most likely due to:The influx of the patient’s own cells and fluids into the treatment site. •INFUSE Bone Graft has not been studied in patient who are skeletally immature (<18 years of age) or no radiographic evidence of epiphyseal closure.)
  66. 66. •INFUSE Bone Graft should not be used in patients with an active infection at the operative site. •INFUSE Bone Graft should not be used in the vicinity of a resected or extant tumor, in patients with any active malignancy or patients undergoing treatment for malignancy. •This product has not been tested in pregnant women to determine if it could harm a developing fetus. This product has also not been studied in nursing mothers.
  67. 67. Women of childbearing age should not become pregnant for one year following treatment with the product. Women of childbearing age should be warned of potential risks to a fetus and should discuss other possible treatments with their doctor.
  68. 68. i-FACTOR BIOLOGIC BONE GRAFT P-15/ABM has been in human clinical use for more than 17 years in an estimated 500,000 patients worldwide
  69. 69. i-FACTOR technology is based on the biological activity of a 15 amino acid peptide naturally found in Type I human collagen. The only bone graft that combines a unique anorganic bone ABM particles are a natural form of hydroxyapatite [Ca10(PO4 ) 6 OH2] mineral (ABM) particles are a natural form of hydroxyapatite [Ca10(PO4 ) 6 OH2] SYNTHETIC REPLICATE OF P-15
  70. 70. 1 ATTRACT P-15 facilitates and expedites ingrowth of bone by promoting the immigration of reparative cells from the surrounding tissues. ATTACH 2 The high affinity between cells and P-15 supports the physiological mechanism in which cells bind to collagen via the domain simulated by P-15 and continue to organize the matrix by tractional forces. Cells attach to and migrate on Type I collagen by haptotactic mechanisms. ACTIVATE P-15 enhances bone formation by facilitating cellular attachment with subsequent increase in cell binding, proliferation, and differentiation of cells increasing TGFb-1, BMP-2, and BMP-7 levels that positively influence all processes of new bone formation. 3

  73. 73. Emdogain is a biological product consisting of a unique group of proteins that are found in developing teeth( enamel matrix derivative) an extract of porcine fetal tooth Amelogenin: The Dominant Protein in Emdogain
  74. 74. • Act in a process mimics normal root development by stimulating release of autocrine growth factors from periodontal ligament undifferentiated mesenchymal cells. • EMD also, stimulates osteoprotegerin, serving to trigger osteoblasts and indirectly inhibit both osteoclastogenesis and osteoclastic function, both of which are important in attaining alveolar bone growth in the area of desired regeneration.
