Mouth-Motion Cyclic Fatigue Testing
Crown specimens are subjected to mouth-motion cyclic fatigue testing which is able to mimic the forces found while chewing. The test is performed by loading the crown specimens through several thousand cycles at a predetermined load. After being examined for cracks, the specimens are then tested for several thousand more cycles at a higher load. This process is repeated until failure occurs.
