Predictable outcomes intended by the application of PRF (platelet-rich fibrin) derivative membranes have created a lack consideration for their consistency and functional integrity. This study aimed to compare mechanical properties through tensile strength analyze structural organization among produced L-PRF (leukocyte platelet-rich fibrin), A-PRF (advanced A-PRF+ fibrin plus) (original protocols) that varied in centrifugation speed time. (n = 12), 19), 13) were submitted traction test, evaluating maximum average traction. For traction, 0.0020, 0.0022, 0.0010 N·mm−2 obtained A-PRF, A-PRF+, L-PRF, respectively; regarding resistance 0.0012, 0.0015, 0.006 obtained, respectively (A-PRF+ > L-PRF). all groups studied, significant results found. In surface morphology observations SEM, matrix showed highly compact with thick fibers present within interfibrous areas apparent destruction red blood cells leukocytes. The protocol dense composed thin elongated seemed follow preferential orientated direction which platelets well-adhered. Porosity was also evident large diameter spaces whereas most porous platelet concentrate greatest fiber abundance cell preservation. Thus, this concluded higher results, indicating better viscoelastic when stretched two opposing forces.

Platelet-rich fibrin, a classical autologous-derived bioactive material, consists of fibrin scaffold and its internal loading growth factors, platelets, leukocytes, with the gradual degradation slow release physiological doses factors. PRF promotes vascular regeneration, proliferation migration osteoblast-related cells such as mesenchymal cells, osteoblasts, osteoclasts while having certain immunomodulatory anti-bacterial effects. has excellent osteogenic potential been widely used in field bone tissue engineering dentistry. However, there are still some limitations PRF, improvement biological properties is one most important issues to be solved. Therefore, it often combined scaffolds enhance mechanical delay degradation. In this paper, we present systematic review development platelet-rich derivatives, structure mechanisms, applications, optimization broaden their clinical applications provide guidance for translation.

Periodontitis is a widespread inflammatory disease that leads to loss of the tooth supporting periodontal tissues. The few therapies available regenerate tissues have high costs and inherent limitations, inspiring development new approaches. Studies shown an capacity for regeneration, driven by multipotent cells residing in ligament (PDL). purpose this review describe current understanding mechanisms driving wound healing regeneration can inform treatment biologic basis underlying established such as guided tissue (GTR) growth factor delivery are reviewed, along with examples biomaterials been engineered improve effectiveness these Emerging those targeting Wnt signaling, cell or recruitment, scaffolds described context healing, using key vivo studies illustrate impact approaches on formation cementum, alveolar bone, PDL.

Abstract In the past decades, personalized regenerative medicine has gained increased attention. Autologous platelet concentrates (APCs) such as PRP, PRGF, and L‐PRF, all serving a source of large variety cells growth factors that participate in hard soft tissue healing regeneration, could play significant role periodontal procedures. This narrative review evaluated relative impact APCs alveolar ridge preservation, sinus floor augmentation, regeneration bony craters around teeth, both single substitute or combination with xenograft.

Abstract One of the most promising approaches to correct periodontal bone defects and achieve regeneration is platelet-rich fibrin (PRF). This systematic review meta-analysis aimed evaluate using PRF compared other regenerative treatments. The data search retrieval process followed PRISMA guidelines. An electronic MEDLINE, Cochrane, PubMed databases was performed, selecting exclusively randomized clinical trials where following were measured: probing depth reduction (PD), attachment level gain (CAL), radiographic fill (RBF). Out 284 selected articles, 32 chosen based on inclusion criteria. use (PRF) + open flap debridement (OFD), metformin, plasma (PRP), OFD/bone graft (BG) significantly reduced PD improved CAL RBF.

Aim: Noncontained (1‐ or combined 1‐ to 2‐wall) periodontal intraosseous defects represent challenging clinical situations with unpredictable surgical therapeutic outcomes. This randomized trial assessed demineralized freeze‐dried bone allograft (DFDBA) low speed‐platelet‐rich fibrin (PRF) membrane compared DFDBA collagen (CM) in the therapy of noncontained stage III periodontitis patients. Methodology: Twenty‐two patients measuring ≥3 mm and attachment loss ≥5 were randomly allocated into two groups: test group (low‐speed PRF + DFDBA) control (CM DFDBA), 11 participants per group. Clinical radiographic assessments conducted at baseline, 3, 6, 9, 12 months for level (CAL; primary outcome), gingival recession depth (GRD), probing (PD), full mouth bleeding score (FMBS) plaque (FMPS), fill linear defect (RLDD; all secondary outcomes). Results: The mean (±SD) CAL‐gain was 2.45 (±1.51), 2.91 (±1.70), (±1.87), 2.82 (±1.83) mm, while (±1.25), 3.27 (±1.27), 3.00 (±1.41), 2.64 (±1.50) months, respectively, no significant intergroup differences ( p > 0.05). Despite absence differences, both groups demonstrated intragroup improvement CAL‐ PD‐gain, RLDD‐reduction as well RLDD < Conclusion: membranes, conjunction DFDBA, show parameters, comparable CMs DFDBA.

Abstract Aim The current randomized controlled clinical trial assessed the effect of injectable platelet-rich fibrin (I-PRF) combined with demineralized freeze-dried bone allograft (DFDBA) compared to DFDBA alone in management intrabony defects stage-III periodontitis patients. Methodology Following sample size calculation, twenty patients ≥ 5 mm attachment level (CAL)-loss and 3 were into test (I-PRF + DFDBA; n = 10) control (DFDBA; groups. CAL (primary outcome), periodontal probing depth (PPD), gingival recession (GRD), full-mouth plaque scores (FMPS), bleeding (FMBS), radiographic linear defect (RLDD), fill (secondary outcomes) examined at baseline, 3, 6, 9 months post-surgically. Results I-PRF independently demonstrated significant intragroup CAL-gain, PPD-, RLDD-reduction ( p < 0.05), no intergroup differences observed > 0.05). CAL-gain (mean ± SD) 2.40 0.70 2.50 0.85 PPD-reduction 3.50 1.18 2.80 0.42 for respectively. Both groups showed RLDD improvement, a 3.58 0.66 3.89 1.57 Stepwise regression analysis revealed that baseline predictors Conclusion Within present study’s limitations, or without resulted improvement parameters surgical treatment Addition does not appear significantly enhance DFDBA’s reparative/regenerative outcomes.
