Silica infiltrated zirconia obtained through the sol-gel method for dental applications

Abstract

Silica infiltration of zirconia used for biomedical application has already been proved to prevent low temperature degradation. In the present study, we will investigate the mechanical and bonding properties (to resin cements and porcelain) of a zirconia infiltrated by silica using a sol-gel method, which has the benefits of being simple, low-cost and cold process.Lately, zirconia infiltration occurs after five day immersion in silica sol and water. In the present work a decrease of 95.5% of the infiltration time is proposed. Therefore, the flexural strength of specimens infiltrated at several times will be measured. The structural homogeneity of the new materials will be quantified by Weibull analysis (95% CI). Microstructure will be characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier Transform Infrared Spectra (FTIR). Additionally, the resistance to scratching (bonding) of veneered specimens, the fracture energy of resin bonded interfaces and the resistance to wear will be measured on infiltrated zirconia. (AU)
