Problems solved by technology

[0002] In the known technical field, the teeth and fixed restorations in the oral cavity will wear and tear under the repeated action of masticatory force. After a long period of accumulation, they may suddenly break due to fatigue stress. The measurement of fatigue life has many positive meanings. In clinical practice, many patients are very concerned about the service life of restorations, but prosthodontists cannot accurately estimate according to the actual situation due to the lack of corresponding experimental basis. How to simulate the oral environment and perform fatigue tests on restorations is of great significance. Significant significance

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 with figure 2 The oral restoration fatigue testing machine shown includes a left side plate 1 and a right side plate 2 which are arranged oppositely, and a fixed bottom plate 3 and a movable bottom plate 3 are respectively arranged at the bottom and the middle of the area between the left side plate 1 and the right side plate 2. The prosthesis test piece platen 4 that moves vertically up and down reciprocatingly, on the sample platen 4, there are two rows of prosthetic test piece mounts 5 evenly arranged in the shape of “one”. An elastic expansion mechanism 7 driven by an eccentric wheel mechanism is provided above the body test piece mounting seat 5, and an elastic telescopic mechanism 7 corresponding to the prosthesis test piece mounting seat 5 is provided at the bottom end of the elastic expansion mechanism 7. The punch 8 w...

Abstract

The invention discloses a fatigue testing machine for dental prosthesis, which comprises a left side plate and a right side plate which are oppositely arranged, and a fixed base plate and a vertically upper , The restorative test piece platform that reciprocates down and down, on the sample platen, there are multiple rows of prosthetic test piece mounting seats that are evenly arranged in the shape of a "one", and above the prosthetic test piece mounting seats, there are The elastic telescopic mechanism driven by the eccentric wheel mechanism is provided with a punch corresponding to the mounting seat of the prosthetic specimen at the bottom of the elastic telescopic machine, and is applied with a sine wave cyclic load. The invention is simple in structure and reasonable in design, uses the principle of cam mechanism and eccentric wheel mechanism to simulate the chewing conditions in the human oral cavity, and has an artificial saliva circulation device with alternating and variable temperature to simulate the moist oral saliva environment and the different saliva that occurs after eating. Temperature changes, able to conduct scientific fatigue tests on restorations to obtain accurate data for clinical reference.

Description

technical field [0001] The invention relates to a fatigue testing machine, in particular to a fatigue testing machine for oral prosthesis. Background technique [0002] In the known technical field, the teeth and fixed restorations in the oral cavity will wear and tear under the repeated action of masticatory force. After a long period of accumulation, they may suddenly break due to fatigue stress. The measurement of fatigue life has many positive meanings. In clinical practice, many patients are very concerned about the service life of restorations, but prosthodontists cannot accurately estimate according to the actual situation due to the lack of corresponding experimental basis. How to simulate the oral environment and perform fatigue tests on restorations is of great significance. important indications. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fatigue testing machine for dental prostheses, which can...
