This study aimed to develop the new denture resin material which is consist of the bisfunctional siloxane oligomer-MMA copolymer and to investigate the effect of doughing time by changing the composition of the liquid and powder. The powder of the new denture resin material which contain the 0, 10, 30, 50, and 70-mol% ratio of bisfunctional siloxane oligomer and liquid which was MMA, acetone, and MMA with 10 or 20-mol% ratio of bisfunctional siloxane oligomer were mixed under the condition of 25 or 60℃ according to powder-liquid method and measured the doughing time. The powder of the new denture resin material was not changed to dough by any conditions. This study suggested that the powder of the new denture resin material has resistance against MMA and acetone.
