Abstract:
A plastic layer polymerized on the surface of denture base material in a thickness of, in average, 40 microns by means of visible light was significantly harder with respect to industrial acrylic surfaces. At an irradiation time of 90s according to factory prescription no harder surface appeared even in case of multiple covering. The surface became significantly harder with an irradiation of 150s. Of the denture base material products the Trevalon and the QC-20 products showed the forming of significantly harder surface.
