Description

TECHNICAL FIELD

[0001] The utility model relates to the field of implant quality detection technology, more particularly, the utility model relates to a dental implant dynamic fatigue testing device. BACKGROUND

[0002] In the field of dental implantation, the quality of the implant directly relates to the success rate of the implant surgery, as well as the user experience and oral health of the patient. Dental implants need to withstand complex chewing forces in the oral cavity for a long time, which puts high requirements on the fatigue performance of the implant. Therefore, it is crucial to conduct accurate and effective dynamic fatigue testing before the implant is put into clinical use.

[0003] Currently, manufacturers and testing institutions conduct fatigue testing on dental implants to evaluate the mechanical properties of the dental implants, but they cannot accurately simulate the complex chewing movements in the oral cavity, resulting in a large deviation between the test results and the actual use. For example, some devices can only load pressure in a single direction and cannot simulate the relative sliding friction during tooth occlusion, so that problems that may occur in the actual use of the implant cannot be revealed in the test. Some test devices have limited means for monitoring the state of the implant, making it difficult to real-time and comprehensively grasp the wear, deformation, and cracking of the implant during the test process, affecting the accurate evaluation of the quality of the implant. In addition, some test devices are not accurate enough in load force control, which cannot meet the needs of different implants for different load force testing, thereby reducing the reliability and effectiveness of the test.

[0004] Therefore, a dental implant dynamic fatigue testing device is proposed. UTILITY MODEL CONTENT
