title: Dimensional contour stability of acrylic resin bases for complete dentures before and after water sorption.
abstract: OBJECTIVE
  To evaluate the dimensional contour variations of acrylic resin denture bases before and after storage in water.
  
  
  METHODS
  The fit of 40 bases was evaluated by measuring the thickness of a layer made with silicone placed between the bases and the casts. The measurements were repeated on a new set of silicone layers after having stored the bases in water for 42 days.
  
  
  RESULTS
  Significant differences were found both for the maxillary and the mandibular bases.
  
  
  CONCLUSIONS
  Water sorption had an important effect on the contour of the prosthetic bases.
