Concentrated Growth Factors

Platelets release several growth factors which stimulate tissue regeneration. Several techniques for platelet concentrates such as platelet rich plasma (PRP), plasma rich in growth factors (PRGF), platelet rich fibrin (PRF) and concentrated growth factors (CGF) have been introduced in dental surgeries for the prevention of hemorrhage and acceleration of tissue regeneration. However, a fabricating growth factors-enriched bone graft matrix which is called “sticky bone” has been demonstrated to provide stabilization in bony defects. In this article, we presented the method of preparing and utilizing CGF and sticky bone and evaluate the effect of CGF mixed with bone graft and CGF barrier membrane in periodontal surgeries.Methodology: We used websites such as PubMed, Scopus, and ISI Web of knowledge to get related articles about this subject. The research process involved specific key words " concentrated growth factor”- “Platelet rich fibrin”- growth factors-enriched bone graft” - “sticky bone” to find more articles which published from 2007 to March 2018.Results: We reviewed 48 articles, 43 articles were excluded. Only five articles have been conducted. Original human studies and case report were included.Conclusion: We concluded that the use of sticky bone and CGF is effective in bone grafting and implant.

AbstractIn the past 20 years, the platelet concentrates have evolved from first-generation products, i.e., platelet-rich plasma (PRP) and plasma rich in growth factors to the second-generation products such as leukocyte-platelet-rich fibrin (L-PRF) and advanced platelet-rich fibrin (A-PRF). These autologous products with a higher leukocyte inclusion and flexible fibrin mesh act as a scaffold to increase cellular migration in the angiogenic, osteogenic, and antimicrobial potential of these biomaterials in tissue regeneration. In the second-generation platelet concentrates, the protocols are easier, cheaper, and faster with an entire physiological fibrin matrix, resulting in a tridimensional mesh, not as rigid as one of the first generations. This allows the slow release of molecules over a longer period of time and triggers the healing and regenerative process at the site of injury. The potential of A-PRF to mimic the physiology and immunology of wound healing is also due to the high concentration of growth factors released as follows: vascular endothelial growth factor, platelet-derived growth factor, transforming growth factor-β, and anti-inflammatory cytokines that stimulate tissue cicatrization, vessels formation, and bone cell proliferation and differentiation. Furthermore, the number of neutrophils and monocytes/macrophages is higher releasing important chemotactic molecules such as chemokine ligand-5 and eotaxin. Thus, L-PRF and A-PRF have been used, especially in implantology, periodontology, and maxillofacial surgery. Future clinical applications include tissue regeneration/grafts, ulcers/skin necrosis in the diabetic patient and others, plastic surgery, and even musculoskeletal lesions.

<p>The aim of any invasive procedure is the complete eradication and elimination of the infection and associated necrotic tissue followed by repair and regeneration of the affected tissue. In order to achieve this goal various biological products have been introduced, among which are present the platelet concentrates. Platelet concentrates with their higher concentration of platelets has been used in the field of medicine since the 1990s in the form of the first-generation concentrates-Platelet Rich Plasma, and the second generation concentrated -Platelet Rich Fibrin. Choukroun’s Platelet Rich Fibrin is one such material, which is used by itself and also as an adjunct with grafts. It has been successful as it delivers high doses of growth factors and has anti-inflammatory properties. They have been shown to be of great promise in the field of dentistry, ranging from implantology; Sinuses lift procedures, treating of endodontic and periodontal lesions to regeneration of necrotic pulp. This novel technique has the potential to revolutionize the treatment mode in dentistry and help with reducing patient morbidity. We will be further looking into the specification and implications of this material in this review.</p>

Different Types

Platelet concentrates have been widely used in regenerative medicine, including endodontics. The aim of this manuscript was to assess critically the efficacy of PRF in the treatment of endodontic periapical lesions in adult patients on the basis of the literature. The PICO approach was used to properly develop literature search strategies. The PubMed database was analyzed with the keywords: “((PRP) OR (PRF) OR (PRGF) OR (CGF)) AND (endodontic) AND ((treatment) OR (therapy))”. After screening of 155 results, 14 articles were included in this review. Different types of platelet concentrates are able to stimulate the processes of proliferation and differentiation of mesenchymal stem cells. Platelet rich fibrin (PRF) releases growth factors for at least 7 days at the application site. Growth factors and released cytokines stimulate the activity of osteoblasts. Moreover, the release of growth factors accelerates tissue regeneration by increasing the migration of fibroblasts. It was not possible to assess the efficacy of PRF supplementation in the treatment of endodontic periapical lesions in permanent, mature teeth with closed apexes, due to the lack of well-designed scientific research. Further studies are needed to analyze the effect of PRF on the healing processes in the periapical region.

Background: Platelet-rich plasma (PRP) is widely used in sports medicine. Available PRP preparations differ in white blood cell, platelet, and growth factor concentrations, making standardized research and clinical application challenging. Purpose: To characterize a newly standardized procedure for pooled PRP that provides defined growth factor concentrations. Study Design: Controlled laboratory study. Methods: A standardized growth factor preparation (lyophilized PRP powder) was prepared using 12 pooled platelet concentrates (PCs) derived from different donors via apheresis. Blood samples and commercially available PRP (SmartPrep-2) served as controls (n = 5). Baseline blood counts were analyzed. Additionally, single PCs (n = 5) were produced by standard platelet apheresis. The concentrations of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), platelet-derived growth factor AB (PDGF-AB), transforming growth factor β1 (TGF-β1), insulin-like growth factor 1 (IGF-1), interleukin (IL)–1α, IL-1β, and IL-1 receptor agonist (IL-1RA) were analyzed by enzyme-linked immunosorbent assay, and statistical analyses were performed using descriptive statistics, mean differences, 95% CIs, and P values (analysis of variance). Results: All growth factor preparation methods showed elevated concentrations of the growth factors VEGF, bFGF, PDGF-AB, and TGF-β1 compared with those of whole blood. Large interindividual differences were found in VEGF and bFGF concentrations. Respective values (mean ± SD in pg/mL) for whole blood, SmartPrep-2, PC, and PRP powder were as follows: VEGF (574 ± 147, 528 ± 233, 1087 ± 535, and 1722), bFGF (198 ± 164, 410 ± 259, 151 ± 99, and 542), PDGF-AB (2394 ± 451, 17,846 ± 3087, 18,461 ± 4455, and 23,023), and TGF-β1 (14,356 ± 4527, 77,533 ± 13,918, 68,582 ± 7388, and 87,495). IGF-1 was found in SmartPrep-2 (1539 ± 348 pg/mL). For PC (2266 ± 485 pg/mL), IGF-1 was measured at the same levels of whole blood (2317 ± 711 pg/mL) but was not detectable in PRP powder. IL-1α was detectable in whole blood (111 ± 35 pg/mL) and SmartPrep-2 (119 ± 44 pg/mL). Conclusion: Problems with PRP such as absent standardization, lack of consistency among studies, and black box dosage could be solved by using characterized PRP powder made by pooling and lyophilizing multiple PCs. The new PRP powder opens up new possibilities for PRP research as well as for the treatment of patients. Clinical Relevance: The preparation of pooled PRP by means of lyophilization may allow physicians to apply a defined amount of growth factors by using a defined amount of PRP powder. Moreover, PRP powder as a dry substance with no need for centrifugation could become ubiquitously available, thus saving time and staff resources in clinical practice. However, before transferring the results of this basic science study to clinical application, regulatory issues have to be cleared.
