AbstractBackground:Different barrier membranes and augmentation techniques are used in oral surgery to recover lost bone structures with varied success. Recently, a combination between bone graft materials and Platelet-Rich-Fibrin (PRF) is implemented in the periodontology and implantology.Aim: The aim of this case report was to assess the possibility for augmentation of the alveolar ridge in the frontal region of the upper jaw, utilizing a combination of bone graft material, injectable platelet-rich-fibrin (i-PRF) and advanced platelet-rich fibrin (A-PRF).Materials and methods:An 18 year-old male with expulsion of tooth 11 and partial fracture of the alveolar ridge was treated with augmentation of the alveolar ridge using bone graft material, injectable platelet–rich-fibrin(i-PRF) and advanced platelet-rich-fibrin (A-PRF). Clinical results were reviewed 4 months after the augmentation and a dental implant was placed.Results:The postoperative period was uneventful. The control CBCT scan showed good organization of new bone allowing placement of a dental implant.Conclusion:The successful clinical and radiographic results of the case suggest that using A-PRF and i-PRF can be beneficial for bone augmentation of the alveolar ridge before implant placement.

Abstract Purpose The purpose of this study was to evaluate the influence of biodegradable polycaprolactone membrane on new bone formation and the biodegradation of biphasic alloplastic bone substitutes using animal models. Materials and methods In this study, bony defect was formed at the canine mandible of 8 mm in diameter, and the defects were filled with Osteon II. The experimental groups were covered with Osteoguide as barrier membrane, and the control groups were closed without membrane coverage. The proportion of new bone and residual bone graft material was measured histologically and histomorphometrically at postoperative 4 and 8 weeks. Results At 4 weeks, the new bone proportion was similar between the groups. The proportion of remaining graft volume was 27.58 ± 6.26 and 20.01 ± 4.68% on control and experimental groups, respectively (P < 0.05). There was no significant difference between the two groups in new bone formation and the amount of residual bone graft material at 8 weeks. Conclusion The biopolymer membrane contributes to early biodegradation of biphasic bone substitutes in the jaw defect but it does not affect the bone formation capacity of the bone graft.

The material properties of nanocellulose (NC) can effectively enhance the structural stability of composite materials. However, the research related to NC/α-calcium sulfate hemihydrate (CSH) composites is largely lacking. In this paper, we explore the combination of these two materials and determine their elaborate biological activities in vivo. Using α-CSH as the matrix, the composite bone graft materials were produced according to different proportions of NC. Then the mechanical strength of the composite bone graft was measured, and the results were analyzed by X-ray diffraction and scanning electron microscopy (SEM). To conduct the material in vivo evaluation, 0% (CN0) and 0.75% (CN0.75) NC/α-CSH composite bone graft materials were implanted into a femoral condyle defect model. The results indicated that NC could significantly enhance the mechanical properties of α-CSH. The SEM analysis indicated that the NC shuttled between the crystal gaps and formed a three-dimensional network structure, which was firmly combined with the crystal structure. Meanwhile, the CN0.75 scaffold remained at 12 weeks postoperation, which provided a long-term framework for new bone formation. Overall, our findings demonstrate that, with a 0.75% NC/α-CSH composite demonstrating good potential as a bone graft material for clinical bone grafting.
