Submitted by Assist. Lect. Muntadher Saleh Mahdi . <br /> The nanotechnology entails the investigation and technological advancement of materials, devices, and systems within the size range of 0.1–100 nm, with the primary objective of producing goods that are more durable, affordable, and accurate. Nanotechnology aims to improve the efficacy of medical implants (like bone-anchored prosthesis) by modifying their surface topography to increase biocompatibility, altering their composition to enhance mechanical properties, and influencing tissue responses to accelerate healing and enable immediate loading by modulating bone formation. When the material is nano-sized, the surface area is larger than when it is micro-sized, which increases the adhesive area. Bone tissue cells are a mixture of micro- and nano-sized, with the majority being nano-sized.<br />The attached figure is a FE-SEM image of one of the prosthetic implants, showing the surface topography within the nanoscale range after coating it with a nano-composite.
