title: Effect of surface modified fillers on the water absorption of a (RTV) silicone denture soft lining material.
abstract: OBJECTIVE
  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.
