How to Perform ISO 14801 Dental Implant Testing

Home / Testing Standards / ISO 14801 Dental Implant Testing

Summary of Test

ISO 14801 centers on fatigue testing of dental implants and their prosthetic elements. The test has been used to compare differently designed implants or those of varying size.

Testing should be only performed on a finished specimen. The endosseous dental implant should be assembled according to its intended use. Prior to conducting ISO 14801, it is important to read the entire specification in the relevant publication.

Testing Procedure

If there is evidence of corrosion fatigue, testing should be carried out in a saline bath at a temperature specified in the standard. Otherwise, testing can be conducted in air at 20C.
Mount the specimen in the test fixture in accordance with the standard.
Apply compressive loads sinusoidally to the implant until failure as described in the standard. Perform tests in saline to 2 million cycles. Perform tests in air to 5 million cycles.

Calculations:

Generate a load vs. cycle diagram by showing for each value of applied peak load the number of cycles to failure
