Oral environment simulation test machine

Abstract

The invention discloses an oral environment simulation test machine comprising a stomatognathic two-free-degree motion unit, intraoral liquid spouting units, an intraoral temperature adjusting unit and a control unit. The stomatognathic two-free-degree motion unit, the intraoral liquid spouting units and the intraoral temperature adjusting unit are respectively connected with the control unit and arranged in an integral framework of the test machine. The stomatognathic two-free-degree motion unit is arranged at the front end of the integral framework of the test machine for observers to observe simulation states of stomatognathic two-free-degree chewing movements in a window form. The intraoral liquid spouting units are arranged on the rear end and the lower end of the integral framework of the test machine. The intraoral temperature adjusting unit is arranged on the front end of the integral framework of the test machine. The control unit is arranged between the stomatognathic two-free-degree motion unit and the intraoral liquid spouting unit. The oral environment simulation test machine achieves frictional wear and fatigue test between extra-oral dentures and natural teeth, and oral environment simulation of a service life forecast experiment under a simulate real oral environment.

Description

technical field [0001] The invention belongs to a device which can be applied to carry out friction and wear, fatigue test and life prediction test between extraoral dentures and natural teeth under the simulated real oral environment, in particular to an oral environment simulation testing machine. Background technique [0002] Dentures replace natural teeth in the mouth to perform the occlusal function for a long time, and inevitably wear and tear with natural teeth or dentures themselves. Whether natural teeth are worn or dentures are worn, it will affect the restoration effect. At the same time, it is easy to cause problems such as the failure of chewing function, the increase of the interdental space, and the decrease of the vertical distance of occlusion, and even have a certain impact on the chewing muscles of the human body. Especially the problem of wear matching between dentures and natural teeth has been the focus of attention of dentists and researchers in r...

AI Technical Summary

Problems solved by technology

A good oral environment simulation testing machine must be an electromechanical system based on the knowledge of stomatology, but often due to the lack of professional mechanical and control knowledge of researchers engaged in the research of friction and wear of dentures and natural teeth, the authenticity of the simulation of occlusal movement is not enough. It is not possible to directly use dentures and natural teeth for friction and wear research, and the degree of automation is not high; at the same time, due to the lack of ready-made denture processing equipment (expensive), most testing machines cannot directly conduct friction and wear tests between dentures and natural teeth.
