Surface detail reproduction of hydrophillic polyvinyl siloxane impression materials, dental stone and liquid media

ABSTRACT

The aim of the study was to evaluate surface detail reproduction of hydrophilic poly vinlysiloxane impression materials and dental stone mixed with different liquid media. Four systems were arranged in order that each system contained impression material and dental stone mixed with three different liquid media. Experiments were carried out in accordance with ADA specification No. 19 for elastomeric impression materials and surface detail reproduction was evaluated by means of a traveling microscope. Analysis of data revealed that, large main effect variations caused by differences between impression materials and by differences between dental stones while no significant main effect variation was found to be caused by differences between liquid media
