Bone grafting and its effect on stablilty of the jaw on extraction patients: a systematic review
… molars. Typically, during extraction procedures, bone grafting material is inserted to minimize bone loss. Bone grafting has become a standard procedure in dentistry and an essential component in modern medicine. The practice started nearly 350 years ago when a Dutch doctor in 1668 performed the …

Evaluation of Two Techniques of Cancellous Bone Grafting of Experimental Subchondral Bone Cysts in the Medial Femoral Condyles of Horses
… 5 horses to mimic clinical cases of subchondral bone cysts after debridement. The defects were created with either a standard square ended drill bit or a compaction drill bit. The compaction drill bit compresses bone laterally and distally creating a dense wall and floor. Twelve-mm sternal …

Long-term osteointegration of BMP-2 eluting hydroxyapatite scaffolds for bone tissue engineering
… and tumor resections can result in discontinuity bone defects, which are typically treated through bone grafting. Potential limitations, such as donor site morbidity, make the development of synthetic implants with similar success to current techniques an attractive alternative for the repair of …

Treatment of enchondroma of hand using calcium sulfate and autobone grafting
… treated by curettage followed by cancellous grafting. Auto-bone grafting should be done in general anesthesia to harvest from the iliac crest, and there is donor-site morbidity such as pain and possible infection. Therefore, we studied the efficacy of injectable calcium sulfate as bone …

Engineering Musculoskeletal Tissue: In vitro and in vivo evaluation of novel scaffolds and growth factors for bone regeneration
… The management of bony non-unions and large bone defects due to congenital deformities, trauma, degenerative disease, and oncological resection remains a complex challenge for orthopaedic surgeons. Currently, autologous bone grafting is the ‘gold standard’ treatment for non-unions and large …

Allograft bone in hip revision: the effect of locally applied pharmacological treatment.
… 2,300. During implant loosening, some of the bone in the femur is lost, which can make the revision more difficult. One way of handling bone loss has been the impaction technique. Allograft bone is morsellised and impacted into the defect before a prosthesis is inserted. Mechanically, the …

The synergistic effect of pulsed electromagnetic fields and demineralized bone matrix on the osteogenic differentiation of mesenchymal stem cells
Orthopaedic bone grafting continues to be a mainstay in the treatment of non unions and other difficult to heal bone defects. Tissue engineering strategies have focused on providing bone graft materials that are osteoconductive, osteoinductive and osteogenic in order to achieve optimal bone …

“Out with the old and in with the new” - A retrospective review of paediatric craniocervical junction fixation: indications, techniques and outcomes
… rates were 80% and 90.5% respectively. Allograft bone grafting was found to be a significant risk factor for non-union. Conclusion: The screws can be safely and predictably placed as confirmed on radiological follow-up with a high fusion rate and an acceptable complication rate. Uninstrumented …

Development and evaluation of the innovative 3D printed scaffolds for bone regeneration in vitro and in vivo /
Nowadays, the number of performed bone augmentation surgeries in various fields of medicine is growing. Bone augmentation is performed by restoring a bone defect with various bone substitutes. However, they fail to match all the ideal bone graft criteria. Therefore, the limitations of existing bone …

Use of growth factors and adhesive ligands to promote connective tissue progenitor colony formation from fresh marrow
The current gold standard for bone graft material is autologous bone, which provides mechanical support, possesses factors that promote bone formation, and contains connective tissue progenitors (CTPs), a heterogeneous population of connective tissue stem and progenitor cells that contribute to …

Development of polyHIPE scaffolds for improved bone regeneration
Critical size bone defects resulting from trauma or disease are challenging to treat due to the size and shape of the defect. Autologous tissue remains the gold standard due to the superior healing potential but harvesting material is challenging due to donor site complications. We have designed a …
