background: ligament reconstruction is a common procedure in orthopedic surgery. although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. purposes: we sought to introduce our new technique of bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (acl) reconstruction and to compare ...

The aim of this study was to evaluate the regeneration bone defects created in femoral condyle osteoporotic rats, following intravenous (IV) zoledronate (ZA) treatment three settings: pre-bone grafting (ZA-Pre), post-bone (ZA-Post), and pre- plus (ZA-Pre+Post). Twenty-four female Wistar rats were ovariectomized (OVX). After 12 weeks, left condyle. All grafted with a particulate inorganic cancel...

BACKGROUND Despite the causal association between variant Creutzfeldt - Jakob disease and bovine spongiform encephalopathy (BSE), bovine origin graft materials are widely used during dental surgical procedures. The aim of this study was to assess the risk of BSE transmission through anorganic bovine bone substitutes. METHODS Electronic database of MEDLINE was searched to identify relevant stu...

Bovine and caprine Monterey Jack cheeses were produced unfortified (cheese) or fortified with milk calcium (Ca-cheese). Five groups of male rats were fed a control diet or one of four experimental diets: bovine cheese diet, bovine Ca-cheese diet, caprine cheese diet, and caprine Ca-cheese diet to test their effects on calcium absorption as well as bone mineralization. Significant differences (P...

The study compared the mechanical properties of human bone, fresh bovine bone and a new highly purified bone xenograft: T650 (Lubboc-Laddec). Destructive, compressive tests were performed to determine Young's modulus and ultimate strength, with a constant deformation rate of 0.025 mm min-1. The stress-strain curves obtained from all the non-human specimens especially the T650, did not differ si...

INTRODUCTION The use of bone grafts in orthopedic, maxillofacial and dental surgery has been growing. Nevertheless, both fresh autografts and frozen allografts have limitations, and therefore, alternative synthetic or natural biomaterials, such as processed and lyophilized bovine bone graft have been developed. OBJECTIVE To evaluate in vitro and in vivo biocompatibility of lyophilized bovine ...

Bone morphogenetic protein (BMP) is the only cytokine that induces heterotopic new bone. BMP has been classified as a subfamily of TGF superfamily. The most important and essential aspect for clinical application replenishment reinforcement bone defects fragile areas with However, it difficult to ascertain long term results. In this study, we examined osteogenic potential in mouse femoral fasci...

Background :
 The use of Bone Graft in the management Defect is a challenge world orthopedics. Recently, eggshell containing hydroxyapatite has become new hope an economical and efficient bone graft treatment defects. aim this systematic review was to explore available literature on clinical performance eggshells as grafts guided regeneration.
 Method Two databases (PubMed Cochrane) w...

62 INTERNATIONAL DENTISTRY – AUSTRALASIAN EDITION VOL. 7, NO. 1 Abstract The purpose of this study was to evaluate the repair process in the reconstruction of the anterior wall of the frontal sinus of monkeys with bovine bone matrix. Four adult Cebus apella monkeys underwent an ostectomy of the anterior wall of the frontal sinus. The frontal sinus mucosa and the nasofrontal duct were not manipu...

This study evaluated the morphological and chemical composition of the following bone substitutes: cancellous and cortical organic bovine bone with macro and microparticle size ranging from 1.0 to 2.0 mm and 0.25 to 1.0 mm, respectively; inorganic bovine bone with particle size ranging from 0.25 to 1.0 mm; hydroxyapatite with particle size ranging from 0.75 to 1.0 mm; and demineralized freeze-d...
