Compression-Torsion-Fatigue Test on Dental Products Under Physiological Environmental Conditions

In this test up to five specimens are placed in a water bath at the same time and are loaded at a testing frequency of up to 25 Hz axially, torsionally or with a transverse motion via an intermediate test piece. The forces are recorded by a load cell between the actuator piston and test die, or by 3-component load cells below the water bath.

• According to ISO 14801-07
• Controlled axial preload (50 N)
• Dynamic torsion (angle control ± 3°)
• Temperature conditioning 37°C
• Test frequency up to 25 Hz
• Six specimens simultaneously
• Saline solution, temperature conditioning
• Visual evaluation: the quality of the surface is evaluated after the test
