Radiographic comparison of the repaired bone in maxillary alveolar cleft of dog by tissue engineering and autogenous bone grafting techniques
BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...
متن کاملTissue Engineering in Maxillary Bone Defects
BACKGROUND Restoration of craniofacial bone defects has been a concern for oral and maxillofacial surgeons. In this study, the healing effect of fibrin glue scaffold was compared with autologous bone graft in mandibular defects of rabbit. METHODS Bilateral unicortical osteotomy was performed in the diastema region of 10 male Dutch rabbits. The subjects were randomly divided into 2 equal group...
متن کاملBone Tissue Engineering: a Mini-Review
Despite advances in bone tissue engineering, auto grafts from intra-oral or extra-oral donor sites are still the gold standard for treatment of large craniomaxillofacial defects. Biomaterial development, application of growth factor, and stem cells, open new gateway to bone regeneration studies, but real translation from bench to bedside have not yet happened. In this review article, a number o...
متن کاملFabrication of Porous Hydroxyapatite-Gelatin Scaffolds Crosslinked by Glutaraldehyde for Bone Tissue Engineering
In this study, to mimic the mineral and organic components of natural bone, hydroxyapatite[HA] and gelatin[GEL] composite scaffolds were prepared using the solvent-casting method combined with a freeze drying process. Glutaraldehyde[GA] was used as a cross linking agent and sodium bisulfite was used as an excess GA discharger. Using this technique, it is possible to produce scaffolds with mecha...
متن کاملA Review on Commonly Used Scaffolds in Tissue Engineering for Bone Tissue Regeneration
Introduction: Bone is one of the tissues that have a true potential for regeneration. However, sometimes the bone defects are so outsized that there is no chance of bone self-repair and restoration or the damage is such that it is not possible to repair with medical or surgical interventions. In these situations, bone grafts are the treatment of choice, but due to several obstacles, including l...
