Simulated tooth brushing apparatus used for testing wear resistance of oral restoration material

Abstract

The invention discloses a simulated tooth brushing apparatus used for testing the wear resistance of an oral restoration material. The apparatus comprises a shell, the inner cavity of the shell is sequentially provided with a solvent storage device, a slide rail and a chute from top to bottom, the solvent storage device is fixedly connected with the top end of the shell, the top of the solvent storage device is provided with a cover plate, the cover plate is positioned at the upper side of the shell, the slide rail is sequentially provided with a left slide block and a right slide block in a fitting manner from left to right, the left end of the left slide block is connected with the inner wall of the left side of the shell through a telescoping rod 2, a polishing motor is arranged in the left slide block, the shaft end of the polishing motor is a spline shaft, the spline shaft and a spline shaft sleeve are arranged in a fitting manner, the lower end of the spline shaft sleeve is connected with a polishing wheel, and the spline shaft sleeve is connected with the lower end surface of the left slide block through a telescoping support 2. The above novel practical apparatus realizes a fully-automatic unmanned experiment process, effectively avoids influences of extraneous environment on experiment results through adopting fully sealed experiment environment, and is helpful for improving the credibility of the experiment result.

Description

technical field [0001] The invention relates to the technical field of material testing, in particular to a simulated brushing device for testing the wear resistance of oral restorative materials. Background technique [0002] Oral diseases occur frequently, and dental diseases are the most common. Among them, oral and systemic diseases induced by caries seriously affect human health. The incidence of caries in my country is as high as 80%, and the prevalence rate of the elderly is as high as 98.4%. Dental care and Treatment is urgent. According to the degree of caries, the repair methods mainly include fillings to repair caries (such as composite resin, silver amalgam, etc.) and whole teeth to replace carious teeth (such as ceramics, metal implants, etc.), and the key to restoration is oral restoration materials, research and development of feasible materials , improve product performance, and provide a direct and effective solution to meet clinical needs and solve dental p...

Problems solved by technology

The brushing process is another important form of friction of oral restorative materials during service. According to the calculation of brushing three times a day, the average number of frictions on the teeth is 200 times. The long-term brushing process will inevitably cause wear and tear on the materials. There are few reports on the test equipment and research evaluation system for the loss of oral restorative materials during the process
