introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...

introduction : efforts are being made to improve the efficacy of biomaterials used as bone substitutes for bone regeneration in the oral and maxillofacial region. graft materials have been recently produced in iran; however, studies are required to confirm their efficacy. this study aimed to compare the histomorphometric results of using mineralized allografts produced by the hamanandsaz baft k...

introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...

Background: In several conditions we have face cranial bone defects. Reconstruction of these defects remains one of the most challenging problems encountered by craniofacial surgeons. Objective: To evaluate bone repair in cranial bone defects by use of an implant made of octacalcium phosphate in combination with bone matrix gelatin (OCP/BMG). Methods: We used 40, 5–6-week-old male Sprague-Dawle...

background and aims. autogenous bone graft is commonly used for reconstruction of bone defects in routine surgical procedures. the complexity of producing bone grafts and their application has lead to the use of human bone matrix gelatin (hbmg). the present study was conducted to compare the efficacy of hbmg and autograft on the reconstruction of bone defects in rats. materials and methods. in ...
