Description

Technical Field

[0001] The invention relates to the technical field of load fatigue monitoring, and in particular to a dental implant fatigue tester and a test method. Background Art

[0002] The dental implant fatigue tester is based on the principles of material mechanics and biomechanics. It simulates the stress conditions of dental implants in the oral cavity during chewing, biting and other actions, and conducts long-term, continuous and repeated loading tests on the implants. By precisely controlling the size, frequency and direction of the loading force, the deformation, stress distribution and fatigue damage of the dental implants can be monitored in real time.

[0003] After searching, the Chinese invention patent with publication number "CN117517054A" discloses "a dynamic load fatigue test device and test method for dental implants". This application realizes forward and backward or left and right movement and horizontal rotation through adjusting components, so that the force block on the dental implant sample can be parked at the center position below the loading block of the fatigue tester. At the same time, it can heat the liquid medium and the air in the container to meet various medium and temperature environment requirements;

[0004] In addition, the Chinese invention patent with publication number "CN111198141A" discloses a "method for predicting fatigue life of polymer-based composite materials based on micromechanics". The application calculates the microscopic stress in each component (fiber and matrix) of the composite material by using a typical equivalent volume unit model (RVE), and then converts the microscopic multiaxial fatigue stress into a uniaxial equivalent average stress and equivalent stress amplitude. Combined with the creep rupture dynamics theory, a equivalent life diagram (CLD) is established to predict the creep / fatigue life. At the same time, the model introduces the linear dependence of the fatigue parameters of each component of the composite material on temperature, which can predict the fatigue life of the composite material at different temperatures, which is conducive to people's effective prediction of the service life of equipment made of polymer-based composite materials.

[0005] Finally, the Chinese invention patent with publication number "CN106593970 A" discloses "a hydraulic loading device for fatigue testing of rigid materials". The application controls the oil cylinder through a loading pump station and can cyclically apply tension and pressure to the tested material. The loading pump station includes a plunger pump I, a plunger pump II, an eccentric wheel, a cam and a reversing valve. The cam coaxial with the loaded plunger pump controls the reversing valve to switch the hydraulic system oil circuit, and the working reliability is very high.

At the same time, the circuit in the electric control cabinet 101 and the servo motor 102 should be cleaned and inspected to ensure its long-term stable operation.

[0055] like Figure 1-Figure 9As shown, the present invention provides a technical solution: a dental implant fatigue tester, comprising: an energy supply component 1, used to provide intermittent rotation driving force, a placement plate 4, installed on the top surface of the energy supply component 1, used to install a carrying component 5 and a control terminal 6, and a plurality of test components for dental implant fatigue testing are installed on the top of the carrying component 5.

[0065] As a preferred embodiment, this embodiment is a supplement to all the above embodiments. In this embodiment, the method of using the dental implant fatigue tester includes: placing the dental implant to be tested on the placement block 807 of the pressurizing component 8 through the filling tube 805 to ensure that the dental implant is firmly placed in the groove formed by the threaded teeth, closing the cover bolt 806 to seal the filling tube 805 and the threaded channel 804 to prevent accidental falling off or contamination during the test, starting the control terminal 6, and controlling the servo motor 102 in the energy supply component 1 to start working, the servo motor 102 drives the connecting shaft 505 to rotate, and then drives the transmission arm 504 to move in the transmission slide 502 and the trigger slide 503 in the disc table 501, so that the pressurizing component 8 and the heating component 7 are alternately in contact with the trigger component 9 as the transmission arm 504 moves, and in the pressurizing component When the gear 802 of the component 8 is meshed with the half-wall toothed disc 902 of the trigger component 9, the gear 802 drives the plug-in tube 808 and the internal placement block 807 to rotate, and at the same time, the telescopic rod 803 produces a telescopic movement under the action of the internal spring or mechanical structure, applying periodic pressure changes to the dental implant, simulating the chewing force in the oral environment, and performing a part of the fatigue test.

Specifically, the intelligent feedback module includes a high-precision sensor network. These sensors are distributed in the pressurizing component 8, the heating component 7 and the triggering component 9, and can accurately capture multi-dimensional information such as pressure, temperature, displacement and microscopic morphology changes on the surface of the dental implant, and transmit the data collected by the sensor in real time through a high-speed data transmission interface. The built-in processor of the control terminal 6 performs algorithm analysis. When the analysis result shows that the current test conditions deviate from the preset standard, the adaptive adjustment module is immediately started. For example, if it is detected that the dental implant has abnormal stress concentration or deformation acceleration under a specific pressure cycle, the adaptive adjustment module automatically adjusts the output power of the servo motor 102, slows down or speeds up the movement speed of the transmission arm 504, and thus fine-tunes the loading frequency and amplitude to adapt to the actual tolerance of the dental implant. At the same time, the heating tube 701 of the heating component 7 can also intelligently adjust the heating power according to the feedback from the temperature sensor to ensure that the test environment temperature is always maintained within the preset range to simulate a more realistic oral environment.
