Evaluation of friction in different oral restoration materials and its influencing factors

This research uses nanotechnology and molecular assembly technology, using biocompatible hydroxyapatite material as the inorganic filler, organically compound and assemble with the organic resin matrix to achieve the performance shear of the composite material, thus developing strength High-resistance, easy-to-process and good biocompatibility composite resin dental restoration materials, and the nano-composite resin material flexural strength, compressive strength and water absorption value were characterized in laboratory stage, the performance fully reached the current clinical use Various indicators of imported composite resin. This study analyzed the differences in the effects and friction properties of different prosthetic materials in oral repair. In order to better simulate the friction and wear performance of dental restoration materials in the oral environment, this paper studied under two conditions of oil lubrication and artificial saliva lubrication, and the wear mechanism from the macro aspects of friction coefficient, wear rate, wear resistance, etc. The research results show that the abrasion performance of the nanocomposite resin is closely related to its surface morphology and characteristics. The comparison with the performance of ceramic and composite resin restoration materials shows that nanocomposite resin materials have better mechanical properties and resistance than other dental restoration wear performance.
