Design of an innovative fatigue test bench for dental implants
Nowadays, dental implant fatigue tests are commonly performed in direct stress fatigue test benches. Even though the accuracy of these machines is very high, they can only test one specimen simultaneously. Besides, taking into account that each test may last several days, a dental implant fatigue characterization may become a very costly task. Furthermore, the technological complexity of these test benches is very high, so the acquisition and maintenance usually have a large cost.
In this sense, the aim of this work is to develop an innovative and efficient test bench based on a cam-follower mechanism. The load that the specimen with-stands, is generated by the compression of a spring caused by the rotation of a cam. Moreover, the new test bench is able to test several specimens at the same time while fulfilling the ISO 14801 standard. As a result, a simple and affordable patent-pending test bench is obtained which is able to obtain dental implants S-N curves in a more efficient way.
