Synthesis of organic-inorganic hybrid compounds based on Bis-GMA and its sol-gel behavior analysis using Taguchi method.

Objectives: The aim of this study was the synthesis of organic-inorganic hybrid compounds based on Bis-GMA and incorporation of them into conventional Bis-GMA/TEGDMA dental resins. This was achieved by the synthesis of Bis-GMA bearing two -Si(OEt)3 reactive groups (a bridged monomer) and subsequent hydrolysis-condensation reactions with TEOS, in TEGDMA media.

Methods: The structure of the bridged monomer was characterized by using FTIR technique.
