[Water absorption and water solubility of prosthetic materials].

Denture base materials investigated with using surface coating polymers fulfilled requirements of ISO Standards 1567 for water sorption and water solubility. The heat-cured polymer gave up water in a greater extent comparing to the cold-cured one. Further amount of water was retained by the surface treatment of coating. A five times increase of water solubility in samples of cold-cured resin was found comparing to the heat-cured ones. A significant decrease of water sorption was measured by using the surface coating.
