Objectives:
The purpose of the present study was to modify the filler content of an experimental room-temperature vulcanizing (RTV) lining material that demonstrated high water sorption in order to produce a material with low sorption properties.
Methods:
Three new formulations were prepared, each containing different hydrophobic silane-treated silica fillers. Water sorption properties for specimens obtained from these formulations were determined using standard experimental techniques.
Results:
All formulations demonstrated greatly reduced water absorption and low volume change.
Conclusions:
An experimental RTV poly(dimethylsiloxane) denture soft lining material having low water sorption properties has been produced.
