Statement of Problem: Several methods are used to enhance bone repair and new bone formation, and bone matrix gelatin (BMG) is recently introduced. Purpose: The purpose of this histologic and histomorphometric study was to assess the osteogenic potential and the quantity of new trabecular bone formation after implantation of OCP and BMG alone and in combination into the cranial defects in rat. ...
Background : Rebuilding and renovation of lost bone whether because of physiologic or pathologic factors was one of the surgeons’ motivations from the past. Statins are commonly prescribed cholesterol-lowering drugs however, it has recently been shown that they also have the beneficial side effect of enhancing bone matrix formation. As a result, this study evaluates the possible osteogenic ef...

OBJECTIVES To validate a critical-size mandibular bone defect model in miniature pigs. MATERIALS AND METHODS Bilateral notch defects were produced in the mandible of dentally mature miniature pigs. The right mandibular defect remained untreated while the left defect received an autograft. Bone healing was evaluated by computed tomography (CT) at 4 and 16 weeks, and by micro-CT and non-decalci...
Microradiography has been evaluated to measure bone healing into a 5.0mm outer diameter mandibular defect in the rat. This method provides high-resolution radiographs of the defects that can be used for an accurate measurement of bone defect healing. In 12 rats, the defect widths of 42-day-old mandibular defects have been measured both using microradiographs and histological sections. The defec...
Nanocrystalline hydroxyapatite (HA) has good biocompatibility and the potential to support bone formation. It represents a promising alternative to autologous bone grafting, which is considered the current gold standard for the treatment of low weight bearing bone defects. The purpose of this study was to compare three bone substitute pastes of different HA content and particle size with autolo...
BACKGROUND Although three-dimensional (3D) β-tricalcium phosphate (β-TCP) scaffolds serve as promising bone graft substitutes for the segmental bone defect treatment, no consensus has been achieved regarding their optimal 3D architecture. METHODS In this study, we has systematically compared four types of β-TCP bone graft substitutes with different 3D architectures, including two types of por...
BACKGROUND Endosseous dental implants with rough surfaces have been designed to improve early healing, especially in areas of poor bone or insufficient bone quantity. The aim of this study was to histomorphometrically assess the bone-to-implant contact on 3 different rough-surfaced implants following guided bone regeneration. METHODS Mandibular premolars and first molars were extracted in 12 ...
background cleft palate (cp) is a common congenital defect. it makes serious difficulties for cleft-affected children. the gold standard of care is autogenous bone grafting which may cause additional problems in donor site along with disappointing results. tissue engineering is a promising solution for a widespread range of defects and disorders. it is reasonable to utilize this novel technolog...
Abstract Background and Aim: Allografts are a group of grafting materials in two types of DFDBAs and FDBAs with various applications in restoration of osseous defects. Considering high price of foreign brands of these materials, we decided to launch a study and compare 2 types of FDBA and DFDBA osseous powders manufactured by Faravardehaye Peyvandi Iran Company and their application in restora...
