In Vitro Assessment of New Niobium Phosphate Glasses and Glass Ceramics

Article Preview

Abstract:

Niobo-phosphate glasses were produced in order to assess the citotoxicity of samples with different compositions. Different P2O5/Ca ratios were studied in an attempt to correlate the biological behavior of new niobo-phosphate bioactive glasses with conventional bioactive calcium phosphate glasses. The most biocompatible glass composition was chosen to produce glassreinforced hydroxyapatite composites.
