Abstract
Introduction: Titanium is an optimal choice for dental implants. However, lack of surface bioactivity is limiting its use, especially in medically compromised patients, among whom insufficient osseointegration is more prevalent. Coating by bioactive glass can improve their efficacy leading to better implant-to-bone bonding, particularly 70S30C being the most bioactive among the binary calcium silicate glass systems. Nanoparticle coatings induce osteoblastic cell attachment and proliferation, have good affinity to bone and possess stronger interfacial bonding to substrate. Objectives: The aim of the current study was to develop a surface coating of sol-gel 70S30C bioactive glass nanoparticles on titanium dental implants, and to characterize the resultant coating from the standpoint of nano-roughness. Methodology: Bioactive glass (BAG) was prepared using modified sol-gel technique, then milled into nanoparticles. Particle size of resultant milled powder was measured by Transmission Electron Microscope. Grit-blasted/acid-etched titanium dental implants were coated with bioactive glass nanoparticles via electrophoretic deposition. Average surface nano-roughness of BAG coated implants was analyzed by Atomic Force Microscope. Results: Bioactive glass nanoparticles showed particle size of
