The purposes of this preliminary study were to investigate the effect of increased Ca contents (5–10 wt% Ca) in Mg-Ca alloy on the mechanical properties and osseous healing rate in a standard rat defect model. Mechanical tests were performed using a compression system followed by qualitative histological analysis using the hemotoxylin and eosin (H&E) staining method and quantitative reverse transcriptase...
Nano hydroxyapatite (HAp) more closely mimics the size of HAp crystals in natural bone and teeth. Due to high surface energy, nano-sized HAp powder can result in better sinterability and, therefore improve mechanical properties. In this present work, nano particle hydroxyapatite was prepared using two methods, wet chemical method and ammoniacal method. The as prepared powder and calcined powder was...
The purpose of this study was to prepare a 3D nanocomposite bone substitute prepared from gelatin (GEL) and synthesized hydroxyapatite (HAP) in order to mimic natural bone feathers through a novel layer solvent casting combined freeze-drying technique. The adhesion between superimposed layers was ensured by applying a GEL solution. Furthermore, samples were cross-linked with 1% glutaraldehyde (GA)...
