Background: There are multiple methods for acceleration of bone healing. Bone marrow has been shown to contain osteoprogenitor cells. Objective: To determine the effect of percutaneous bone marrow injection on bone healing. Methods: 15 mature, 2-kg-weighing white New Zealand rabbits from both sexes were randomized into 3 groups: Group I: Only osteotomy of right radius was performed and a 5 mm b...

crestal bone loss is a biological complication in implant dentistry. the aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique.twenty micro thread implants were placed in 10 patients (two implants per patient). ...

Demineralized bone matrix has been successfully commercialized as an alternative bone graft material that not only can function as filler but also as an osteoinductive graft. Numerous studies have confirmed its beneficial use in clinical practice. Heterotopic ossification after internal fixation combined with the use of demineralized bone matrix has not been widely reported. In this paper we de...

Background: Repair of bone defects is challenging for reconstructive and orthopedic surgeons. In this study, we aimedto histomorphometrically assess new bone formation in tibial bone defects filled with octacalcium phosphate (OCP),bone matrix gelatin (BMG), and a combination of both.Methods: A total of 96 male Sprague Dawley rats aged 6-8 weeks weighing 120-150 g were randomly allocatedinto thr...

background: the aim of this research was to evaluate the effect of adipose derived stem cells on bone repair in through and through mandibular bone defects of canine. materials and methods: in this prospective comparative study, adipose-derived stem cells were isolated from subcutaneous fat of lateral thoracic area of 4 dogs. the isolated cells were cultured and expanded through 3 passages. the...

osteoporosis as a skeletal disorder characterize by compromised bone strength predisposing a person to an increased risk of fracture. all people should be encouraged to take efforts to prevent bone loss and fractures. nutrition is one of several factors that can be modified to reduce osteoporosis risk. the purpose of this review article is assessment the role of the other nutrients the exceptio...

Introduction: Gold standard for alveolar cleft bone grafting is autogenous bone. Advantage of adding the growth factors to the bone is established, so adding PRF to the autogenous bone may have beneficial effects. Methods:  Platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. Results:  Autogenous bone in all (four cases...
