Hollow silica reinforced magnesium nanocomposites with enhanced mechanical and biological properties with computational modeling analysis for mandibular reconstruction.

ABSTRACT: The present study investigates Mg-SiO₂ nanocomposites as biodegradable implants for orthopedic and maxillofacial applications. The effect of presence and progressive addition of hollow silica nanoparticles (0.5, 1, and 1.5) vol.% on the microstructural, mechanical, degradation, and biocompatibility response of pure Mg were investigated. Results suggest that the increased addition of hollow silica nanoparticles resulted in a progressive increase in yield strength and ultimate compressive strength with Mg-1.5 vol.% SiO₂ exhibiting superior enhancement. The response of Mg-SiO₂ nanocomposites under the influence of Hanks' balanced salt solution revealed that the synthesized composites revealed lower corrosion rates, indicating rapid dynamic passivation when com
