Bone Tissue Formation

Rehabilitation of alveolar bone with tissue defect caused by advanced osteoporosis is a common problem in stomatology and maxillofacial surgery. One of therapeutic approaches is implantation of biomaterials. The aim of this study was to estimate biocompatibility, osteoconductive and reparative capabilities of biomaterials in wound healing of rats which are experimentally treated with corticosteroids during 12 weeks to produce osteoporosis. The syngenic Sprague Dolly female rats 6-8 weeks old were divided into the experimental and control groups. In the experimental group comprising 5 subgroups, the bone defects were made in the left mandible by 1.4 mm borer, in sterile conditions. In the first subgroup of rats healing wasspontaneous. In other four subgroups hydroxyapatite (HAp) composite, a mixture of HAp and autologous plasma, a mixture of HAp and fibrin glue, and glass jonomer bone cement were used, respectively. The best results were obtained with a mixture of HAp with plasma. Histologically, the new bone tissue was found in both spongious and compact mandibular parts. Our. results suggest that HAp can help in new bone tissue formation in animals treated with corticosteroids.

Bone Tissue Formation

The global incidence of bone tissue injuries has been increasing rapidly in recent years, making it imperative to develop suitable bone grafts for facilitating bone tissue regeneration. It has been demonstrated that nanomaterials/nanocomposites scaffolds can more effectively promote new bone tissue formation compared with micromaterials. This may be attributed to their nanoscaled structural and topological features that better mimic the physiological characteristics of natural bone tissue. In this review, we examined the current applications of various nanomaterial/nanocomposite scaffolds and different topological structures for bone tissue engineering, as well as the underlying mechanisms of regeneration. The potential risks and toxicity of nanomaterials will also be critically discussed. Finally, some considerations for the clinical applications of nanomaterials/nanocomposites scaffolds for bone tissue engineering are mentioned.

Bone Tissue Formation

Silica aerogels have attracted increasingly more attention due to their extraordinary properties and their existing and potential applications in a wide variety of technological areas. Materials that promote bone-tissue formation at their surface and bond to osseous tissues when implanted are called bioactive, such as pseudowollastonite particles. In this work, the synthesis of aerogels with pseudowollastonite particles was performed. The synthesis involved the preparation of an alcogel by a two step sol-gel route followed by ambient pressure drying. To promote a higher bioactivity the obtained aerogels were then biomimetically treated using simulated body fluids, SBF and 1.5 SBF. A high bioactivity was demonstrated by FT-IR, SEM, EDS, and XRD. The in vitro biocompatibility was assessed by testing cytotoxicity using rat osteoblasts cultures. The results obtained indicate that these materials are highly potential aerogels for bone tissue regeneration.
