“…129,130 Such grafts were also used to enable the insertion of Ti implants into the maxillary sinus floor of 20 patients with acceptable long-term results. 131 On the other hand, the use of pure bioceramics in combination with fibrin glue has shown promising results in terms of handling characteristics of materials and adherence to the surrounding tissues. 132 Woo et al reported injectability of calcium sulfate ceramic powders was enhanced when combined with fibrin glue.…”

Tissue engineering has emerged as a new treatment approach for bone repair and regeneration seeking to address limitations associated with current therapies, such as autologous bone grafting. While many bone tissue engineering approaches have traditionally focused on synthetic materials (such as polymers or hydrogels), there has been a lot of excitement surrounding the use of natural materials due to their biologically inspired properties. Fibrin is a natural scaffold formed following tissue injury that initiates hemostasis and provides the initial matrix useful for cell adhesion, migration, proliferation, and differentiation. Fibrin has captured the interest of bone tissue engineers due to its excellent biocompatibility, controllable biodegradability, and ability to deliver cells and biomolecules. Fibrin is particularly appealing because its precursors, fibrinogen, and thrombin, which can be derived from the patient’s own blood, enable the fabrication of completely autologous scaffolds. In this article, we highlight the unique properties of fibrin as a scaffolding material to treat bone defects. Moreover, we emphasize its role in bone tissue engineering nanocomposites where approaches further emulate the natural nanostructured features of bone when using fibrin and other nanomaterials. We also review the preparation methods of fibrin glue and then discuss a wide range of fibrin applications in bone tissue engineering. These include the delivery of cells and/or biomolecules to a defect site, distributing cells, and/or growth factors throughout other pre-formed scaffolds and enhancing the physical as well as biological properties of other biomaterials. Thoughts on the future direction of fibrin research for bone tissue engineering are also presented. In the future, the development of fibrin precursors as recombinant proteins will solve problems associated with using multiple or single-donor fibrin glue, and the combination of nanomaterials that allow for the incorporation of biomolecules with fibrin will significantly improve the efficacy of fibrin for numerous bone tissue engineering applications.

<b>Clinical Evaluation of a Minimally Invasive Surgical Technique for Maxillary Sinus Floor Augmentation </b>

The purpose of this study, conducted at a private dental clinic, was to clinically evaluate the outcome of a minimally invasive surgical technique for sinus augmentation that carries lower risks of intra-and postoperative complications.We modified the usual steps performed in the sinus augmentation procedure, and discuss the major modifications and resultant improvements, along with a literature review of the original technique in this paper. The modifications and improvements we made in each step are highlighted, and the major modifications are discussed along with a literature review. The biggest improvement most likely resulted from creation of a small fenestration, thereby creating a bag-like structure to keep the graft material in a stable state, which would facilitate better bone formation. In addition, maxillary sinus floor resorption was observed in most cases 2-3 years after surgery, with the resorption reaching the level of or below the tip of the implant. These results suggest that there is no need to take the risk involved in detaching and elevating a large area of mucosa from the inner wall, and that minimal mucosal detachment or augmentation is sufficient and leads to a stable outcome.Our results suggest that minimal-intervention maxillary sinus augmentation is an effective procedure from both patient and bibliographic viewpoints.
