<p>The present invention relates to a dental impression material composition. The dental impression material composition includes organopolysiloxane, an organic-inorganic hybrid composite, a filler, a curing agent, a curing retardant, a crosslinking agent, and a surfactant. The organic-inorganic hybrid composite has a structure wherein organopolysiloxane including a vinyl group is grafted and polymerized in fumed silica in the nano-size dispersed in polyvinylsiloxane. The dental impression material composition includes 5-50 wt% of the organic-inorganic hybrid composite with respect to the total weight of the dental impression material composition. Therefore, the present invention provides the dental impression material composition with high strength which solves problems of coagulation of the filler and decease in fluidity resulted from increase in viscosity.</p> |
