Fatigue test machine for denture base polymers.
A description of a single station fatigue test machine suitable for denture base polymers is given. This machine has been especially designed for dental purposes. A group of representative denture base polymers has been tested, which includes dental poly(methylmethacrylate) of the standard heat polymerized type, autopolymerizing pour type and a heat polymerized rubber graft polymer. These materials were compared and some preliminary results are given. These show that the rubber demonstrated the most satisfactory fatigue life and the pour types were least satisfactory.
