reconstruction methods are an essential prerequisite for functional rehabilitation of the stomatognathic system. plasma rich in growth factors (prgf) offers a new and potentially useful adjunct to bone substitute materials in bone reconstructive surgery. this study was carried out to investigate the influence of prgf and fibrin membrane on regeneration of bony defects with and without deprotein...

various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. this study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bone ceme...

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 ...

background :disruption of anterior cruciate ligament (acl) is a common ligamentous injury of the knee. the choice of graft for (acl) reconstruction remains controversial. this prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (bptb) grafts and four-strand semitendinosus-gracilis (st) grafts for acl reconstruction over a 3-year follow-up interv...

although various techniques have been described for treatment of severe nose deformities, these problems have high revision rates.  conventional nasal septal surgery may not be adequate for all cases. a 21-year-old male patient with nose deformity underwent a nasal surgery. patient had both functional and aesthetic nasal problems. rigid fibular bone graft was used for corrective nasal surgery. ...

conclusions saddle nose reconstruction with bone graft in multiple facial fracture patients is a predictable method if surgical accesses to the region are carefully designed, considering the accompanying fractures. results there were 11 patients treated using this method. the male-to-female ratio was 7:5. one miniscrew with the lag technique was the preferred method for the fixation of the dors...

surgery on the skeleton frequently requires harvesting of autogenous bone graft from the pelvis, but this procedure often is complicated by problems. the purpose of this retrospective, comparative descriptive study was to compare the efficacy of metal-derived bioactive glass (novabone) versus autogenous iliac crest bone graft in adolescent idiopathic scoliosis surgery. the study was carried out...

Background & Objective: This study aimed to investigate the effect of decellularized allogeneic bone graft enriched by periosteal stem cells (PSCs) and growth factors on the bone repair process in a rabbit model, which could be used in many orthopedic procedures. Methods: In this experimental study, a critical size defect (CSD) (10 mm) was created in the ...

introduction: coverage of bone grafts is very important in reconstructive surgery. in edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for upp...
