摘要: Abstract Different analytical methods have been used to investigate the chemical composition of crown and bridge veneering materials. High-performance liquid chromatography with diode array detection system was for identification quantification monomers in resin systems. In addition, gas chromatography, infrared spectroscopy combined chromatography/mass spectrometry were applied purposes. Characterization an oligomeric compound performed using gel permeation chromatography. The weight fraction inorganic fillers determined by combustion analyses total filler content removing soluble part Great variations commercial materials demonstrated.
