Dynamic Fatigue Tests on Dental Implants to ISO 14801

  • Dental implants are used to replace teeth. The implant is embedded in the bone, acting as the root of the missing tooth. The test device for dental implants (chewing simulator) applies an oscillating/pulsating compressive load as specified in ISO 14801. This test enables a comparison of dental implants of different designs or sizes. 
  • Flexible adjustment (between 0° and 50°) of the angle of the implant axis to the test axis, together with a quick-adjust 30° setting, allow this device to be used for testing dental implant systems with and without angled connectors. Embedding the dental implants in a pot allows differences in thread designs to be compensated for and implant lever ratios to be adjusted. The pot with the implant is fixed in the test device with the aid of a clamping device.

The tests can optionally be performed under physiological (in vivo) conditions using the ZwickRoell temperature-conditioning bath. Also available from ZwickRoell is the SAFD (Statistical Analysis of Fatigue Data) program. This technical/scientific software enables practical statistical evaluation of tests in the high-cycle fatigue and long-life fatigue ranges.

The Amsler HC Compact dynamic testing machine features a compact design and extremely low noise, providing an optimal solution for fatigue tests on dental implants in any laboratory when used in conjunction with the test fixture for dental implants (chewing simulator).

Method for compliance with ISO 14801 -07 – Fatigue tests on dental implants

Determination of an S-N curve with a minimum of eleven dental implants:

  • Number of cycles: 5 million or 2 million
  • Test frequency up to 15 Hz or 2 Hz
  • Signal shape: Sine
