Introduction: INTRODUCTION Posterior spinal fusion is a well-known, procedure in spinal surgery. The golden standard to achieve fusion remains autologous bone grafting. Although the exact mechanism of bone formation after grafting is unclear, there are some clues on the processes involved. New bone is originating and progressing from the decorticated processes by (a combination of ) osteoconduc...

Objective- To determine the effect of selected bone graft on the compression properties of radialbone in rabbit.Design- Experimental in vivo study.Animals- A total of 45 adult male New Zealand white rabbits.Procedures- The rabbits were anesthetized and a one-cm-full thickness piece of radial bone wasremoved using oscillating saw in the all rabbit. The rabbits were divided into 5 groups on theba...

Background: Fluoride (F&minus) is a trace element that is incorporated into bone mineral during bone formation. This study assessed the effect of increasing Fluoride doses on the bone formation and microarchitecture on the Femur of rats by histological, and histometrical methods. Materials and Methods: A total of 16 rats was divided into one group of control and three groups of animals that re...

BACKGROUND Statin can induce the gene expression of bone morphogenetic protein-2. Red yeast rice (RYR, Hongqu), i.e. rice fermented with Monascus purpureus, contains a natural form of statin. This study demonstrates the effects of RYR extract on bone formation. METHODS Bone defects were created in the parietal bones of two New Zealand white rabbits. In the test animal, two defects were grafte...

introduction in spite of multiple applications of bioactive glasses, these materials have not been evaluated yet for ridge augmentation. due to the large number of patients who need ridge augmentation and the benefits of nova bone, in comparison with other alloplasts, this study was fulfilled for evaluation of nova bone ability in ridge augmentation. methods the samples of this experimental stu...
