摘要

Titanium (Ti) and its alloys are the most used materials in dental applications due to their favorable biocompatibility, mechanical, and morphological properties. However, clinical failures are observed in these properties, which can be improved by reinforcing Ti nanoparticles (NPs). In this research work, different percentages of silver nanoparticles (AgNPs) and zirconia nanoparticles (ZrO2NPs) have been experimentally reinforced with Ti to develop nanocomposite samples using the sintering method. The developed nanocomposites have been characterized by hardness, surface morphology, Fourier Transformed Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and X-ray diffraction (XRD) tests, and due to the increase of silver content in the samples, hardness and surface roughness increased. Increased surface roughness improves the osseointegration properties of the materials. Different functional groups, such as Ti-OH, C-H, and O-H, were identified in the FTIR analysis. The NPs were uniformly distributed in the samples observed by FESEM images. Microcracks and microcavities were also observed. Crystallinity was observed in the XRD analysis due to the formation of sharp peaks. However, the intensity of peaks decreases significantly due to the increased percentages of AgNPs.
