Description

Technical Field

[0001] This utility model relates to the field of dental material testing technology, specifically to a resin tooth testing device. Background Technology

[0002] Resin teeth are dental restorations made of methyl methacrylate (MDMA) and are widely used in the field of dentistry. Resin teeth require a base material during use. The main function of the resin base is to fix and stabilize the artificial tooth (i.e., denture), ensuring that the denture will not fall out or shift during use. Through the resin base, the artificial tooth can fit snugly against the alveolar bone in the oral cavity, providing stable support. Resin tooth testing is a crucial step in ensuring the quality and safety of resin tooth materials. Resin teeth, especially composite resin materials used for dental restorations and fillings, require testing and evaluation to guarantee their durability.

[0003] Existing resin tooth testing devices place two resin teeth into a wear resistance testing assembly. By pulling the handle up and down, the two resin teeth are clamped and tilted against each other, rubbing against each other repeatedly to test the wear resistance of the resin teeth. The above devices control the frictional contact by moving the resin teeth back and forth. However, in actual use, when the resin teeth are in the biting state, there are often different occlusal contact scenarios between the upper and lower jaws due to different chewing habits and usage scenarios. Testing the frictional performance in a single direction has the problem of poor simulation of the actual usage environment, and there is room for improvement. Summary of the Invention

[0004] This invention addresses the problem that single-direction reciprocating friction performance testing has poor simulation of actual usage environments in scenarios involving bite contact in different directions during testing.
