Title

Preparation and Enhancement of ( Hydroxyapatite/Bioactive glass ) Composite by Mg Nanowires for Dental and bone implants

Pages

  425-431

Abstract

 In this study, some mechanical and physical properties of the composite resin were improved by adding weight percentages of a nano-material, magnesium nanowire, at rates (0-4) %. Some of the techniques that were used, such as X-ray diffraction examination to find out the components of the composite resin from Bioactive glass and Hydroxyapatite, in addition to the scanning electron microscope examination and through it the good distribution of magnesium nanowire material was observed in the composite resin, where the examination shows the homogeneous distribution and full of pores in the composition. By analyzing the results of the research, it can be observed that the compressive strength property improved at 4% magnesium nanowire (208 MPa) and (50 MPa) at 0% magnesium nanowire. Also, an improvement in the wear rate, as the weight loss values decreased with the increase in the percentage of the nano-added material, and the best value was at 4% magnesium nanowire. As for the Thermal conductivity property, its best values were at the highest value of the addition of the strengthening material, and all values were within the permissible range for clinical dental implant applications. As for the examination of the micro-hardness, it was decreasing as the values of addition increased until it reached the lowest hardness at 4% and the highest values of hardness at 0%, which is also within a close range and is allowed in dental implant applications.
