Synthesis and Characterization of Zirconia-Silica PMMA Nanocomposite for Endodontic Implants.

This study aimed to enhance the mechanical properties of PMMA composites by introducing various types of fillers, including ZrO, SiO, and a mixture of ZrO-SiO nanoparticles, which were prepared as prototypes for an endodontic implant. The ZrO, SiO, and mixed ZrO-SiO nanoparticles were synthesized using the sol-gel method and the precursors Tetraethyl Orthosilicate, Zirconium Oxychloride, and a mixture of both precursors, respectively. Before polymerization, the as-synthesized powders were subjected to the bead milling process to obtain a well-dispersed suspension.
