[0002] The dental material wear simulation test apparatus is a specialized device used to evaluate the wear resistance of dental materials. It tests the wear resistance of dental materials by simulating the friction and wear that occur during chewing in the oral cavity.

[0003] For example, patent document CN218382215U discloses a dental material wear simulation testing device, including: a test chamber with a test cavity for placing a dental brace; and a temperature control component, which includes a heating mechanism and a temperature measuring probe. The heating mechanism is located in the test cavity and is used to heat the test cavity, while the temperature measuring probe is located below the clamping mechanism to clamp the dental brace and measure its temperature. This invention uses the temperature measuring probe on the upper clamp to monitor the temperature of the dental brace in real time, and simultaneously uses heating rods around the test cavity and heating pads installed on the lifting mechanism to regulate the temperature in the test cavity, thereby obtaining experimental data that more closely reflects clinical practice.

[0004] In existing technologies, most dental material wear simulation tests are conducted by constant pressure and rotational grinding. However, this test method cannot completely simulate the wear of dental materials during oral chewing. Therefore, a test device that simulates the oral environment and chewing method is set up.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, a dental material wear simulation testing device includes a main body, which includes a test chamber 101. An immersion tank 103 is installed inside the test chamber 101. A clamping mechanism is installed on one side of the immersion tank 103. A grinding mechanism is installed at the upper end of the test chamber 101. The grinding mechanism includes a lifting platform 301. A transmission rod 304 is hinged to the lifting platform 301, allowing relative rotation and relative lifting between the transmission rod 304 and the lifting platform 301. A friction block 305 is fixedly connected to the lower end of the transmission rod 304. A motor 306 is bolted to the top of the lifting platform 301. A grooved cam 308 is fixedly connected to the output end of the motor 306. The grooved cam 308 has a wavy annular groove. A lifting drive rod 309 is hinged to the grooved cam 308. The other end of the lifting drive rod 309 is hinged to the top of the transmission rod 304. A first gear 307 is fixedly connected to the bottom of the grooved cam 308. A bearing is located on one side of the top of the lifting platform 301. A second gear 310 is rotatably connected to the first gear 307. The second gear 310 drives the transmission rod 304 to swing through the linkage assembly. The friction block 305 is fan-shaped and is bolted to the transmission rod 304. In use, the motor 306 drives the grooved cam 308 to rotate. The grooved cam 308 drives the lifting drive rod 309 to rise and fall through the wave-shaped annular groove. The lifting drive rod 309 drives the friction block 305 to rise and fall. The friction block 305 abuts against the dental material test block. At the same time, the grooved cam 308 drives the first gear 307 to rotate. The first gear 307 drives the transmission rod 304 to swing back and forth through the linkage assembly. The transmission rod 304 drives the friction block 305 to swing back and forth. Thus, it is possible to simulate oral chewing and apply intermittent vertical load and reciprocating rubbing and polishing to the dental material test block. Furthermore, by placing the test block in the soaking pool 103 filled with artificial saliva, the oral environment is simulated.

[0030] The linkage assembly includes a first link 311 eccentrically hinged to the second gear 310, and a sliding pin 312 hinged to the other end of the first link 311. A second link 313 is fixedly connected to the top of the transmission rod 304, and the other end of the second link 313 is fixedly connected to the sliding pin 312. The second gear 310 drives the first link 311 to move, and the first link 311 drives the second link 313 to rotate through the sliding pin 312. The second link 313 drives the transmission rod 304 to swing. The sliding pin 312 ensures that the transmission between the first link 311 and the second link 313 is always continuous during the lifting and lowering of the transmission rod 304.

[0031] The front side of the test chamber 101 is rotatably connected to a flip door 102, and a glass observation window is provided on the flip door 102. A liquid injection pump 104 is fixedly connected inside the test chamber 101. An artificial saliva source is connected to the outside of the liquid injection pump 104. The soaking pool 103 contains artificial saliva. When in use, the staff opens the flip door 102 and places the dental material test block between the two clamps 205. Then, before polishing, the artificial saliva is injected into the soaking pool 103 through the liquid injection pump 104.

[0032] The clamping mechanism includes two elastic telescopic columns 202 bolted to the test chamber 101. A clamping platform 201 is bolted to the top of each elastic telescopic column 202. Two symmetrically arranged clamping blocks 205 are slidably connected within the clamping platform 201. A V-groove 206 is formed on one side of each clamping block 205. Two symmetrically arranged side supports 203 are bolted to the test chamber 101. Guide grooves 204 are provided on the side supports 203, and the guide grooves 204 are Z-shaped. One end of each clamping block 205 is slidably connected to the guide groove 204. Two symmetrically arranged side supports 203 are fixedly connected to the test chamber 101. The hydraulic telescopic rod 302 has its output end fixedly connected to the lifting platform 301. The bottom of the lifting platform 301 is fixedly connected to the abutment plate 303, which abuts against the top of the clamping platform 201. In use, the hydraulic telescopic rod 302 drives the lifting platform 301 to descend, the lifting platform 301 drives the abutment plate 303 to descend, the abutment plate 303 forces the clamping platform 201 to descend, and the clamping platform 201 drives the clamping block 205 to descend. Under the action of the guide groove 204, the two clamping blocks 205 are aligned and clamp the dental material test block, and at this time the dental material has been immersed in artificial saliva.

[0033] Working principle: The operator opens the flip door 102 and places the dental material test block between two clamping blocks 205. Before polishing, artificial saliva is injected into the immersion tank 103 via the injection pump 104. The hydraulic telescopic rod 302 lowers the lifting platform 301, which in turn lowers the contact plate 303. The contact plate 303 forces the clamping platform 201 to descend, which in turn lowers the clamping blocks 205. Under the action of the guide groove 204, the two clamping blocks 205 align and clamp the dental material test block. At this point, the dental material is immersed in the artificial saliva. The motor 306 drives the grooved cam 308 to rotate. The grooved cam 308 rotates through a wave-shaped annular groove... The groove-driven lifting drive rod 309 rises and falls, which in turn drives the friction block 305 to rise and fall. The friction block 305 abuts against the dental material test block. Simultaneously, the groove cam 308 drives the first gear 307 to rotate, and the second gear 310 drives the first connecting rod 311 to move. The first connecting rod 311 drives the second connecting rod 313 to rotate through the sliding pin 312. The second connecting rod 313 drives the transmission rod 304 to swing, and the transmission rod 304 drives the friction block 305 to swing back and forth. Thus, it is possible to simulate oral chewing and apply intermittent vertical load and reciprocating rubbing and polishing to the dental material test block. Furthermore, by placing the test block in the soaking pool 103 filled with artificial saliva, the oral environment is simulated.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
