Linear distortion and compatibility of an antimicrobial irreversible hydrocolloid impression material and improved dental stones.

Blueprint Asept Type I irreversible hydrocolloid impression material is claimed by the manufacturers to contain an internal disinfecting agent that is effective within 10 minutes from contact with pathogens. This study examined the accuracy of the material compared with a conventional impression material and its compatibility with two type III and one type IV dental stones. This study did not evaluate the effectiveness of the disinfecting agent.
