The raw materials for dental implants are TC4 rods, and the final products are completed through machining, cutting, cleaning, disinfection and sterilization. When implants are implanted in the human mouth to replace natural teeth, long-term chewing in the oral environment will eventually cause fatigue and cracks in the implants until they break. In order to fully understand the quality standards for oral implants, according to the current national medical industry standard YY / T 0521-2018 dynamic fatigue test requirements for intraosseous dental implants, the implants are fixed at a certain angle and distance on the fixture, and the durability and stability of the implant system are evaluated by simulating various mechanical stresses in the oral environment to ensure safety during long-term use; how to conduct effective and accurate fatigue testing is a problem that needs to be solved.
