Testing of fatigue strength – Astra EV vs. BioniQ

4. July 2014

Bionix machine LASAK company added the next item to fatigue strength of the implant-abutment connection tests (ISO 14801). Astra OsseoSpeed™ EV 3.6S implant, new on the market, failed stength test by load 180 N. Level of strength is about 25 % less than BioniQ® S3.5 implant, which resisted load 240 N. Comparations to the other commercial implant systems is in the graph bellow.
More implant-abutment test information is on Q-Lock connection page.
