[Acrylic denture base materials in dentistry. The influence of immersion of bases on the palatal gap].

The method of experimental design, we used, is versatile enough to allow the study of immersion in water at 37 degrees C during 15 days after curing, as a new parameter able to influence the deformation of denture bases, without any additional experiment. According to the experimental conditions used to make up denture bases, this parameter can, in some cases, modify appreciably the deviation in the palate region.
