Abstract: For improvement of dental services, quality control of dental material such as denture resins seems to be necessary. By quality enhancement of these products, both patient and dentist will be satisfied. The purpose of this study was to assess some practical properties of Stellon QC-20 denture base resin (made by Dentsply Co.) according to ISO 1567. This research was an experimental study according to ISO 1567. Test methods and number of samples were determined in ISO. Assessed parameters were: homogeneity, packing plasticity, color stability, translucency, porosity, bonding to synthetic teeth, residual monomer and flexural strength. Acryl in homogeneity, packing plasticity and translucency passed the experiments. But, the color wasn’t stable according to ISO 7491. Also, it was failed in bonding to synthetic teeth. Residual monomer content of 8 sample solutions was more than 2.2%. So, it was failed in this property. The manufacturer should improve the properties of this material which were failed in the experiments.
